Rivero's contract was selected by the Royals on Friday.

The Royals obviously like Rivero's defense at catcher, but he isn't very appealing in dynasty leagues. He hit .212/.270/.278 in 91 games at High-A in 2019 and should open the year at Double-A.

Garcia was designated for assignment Friday.

He occasionally worked as the Giants' second or third catcher in 2018 and 2019, but never had much success. Garcia also missed time this past year with a hip injury that he is likely fully recovered form at this point.

Feliciano was added to the Brewers' 40-man roster Friday.

Feliciano spent the 2020 season on the Brewers' 60-man roster, but he failed to make his major-league debut. He'll now be protected from the upcoming Rule 5 draft, and he should begin the 2021 season at the Double-A or Triple-A level.

Wong's contract was purchased by the Red Sox on Friday.

Acquired from the Dodgers in the Mookie Betts trade, Wong is Boston's top catching prospect. He spent the summer at the alternate training site after finishing 2019 at Double-A, so he should open the year at Triple-A. Wong has significant right-handed power, but needs to improve his approach at the plate.

Adams was added to the Blue Jays' 40-man roster Friday.

Adams didn't make an appearance in the majors as part of the Blue Jays' 60-man roster in 2020, but he'll be protected from the upcoming Rule 5 draft. The 24-year-old progressed to the Double-A level in 2019, slashing .258/.349/.439 with 11 home runs and 39 RBI.

Herrera's contract was selected by the Cardinals on Wednesday.

Herrera will join the Cardinals' 40-man roster in order to protect him from the upcoming Rule 5 draft. Even if the team doesn't bring Yadier Molina back during the offseason, the 20-year-old has mainly worked in the lower levels of the minors and is unlikely to be considered for a major-league roster spot in 2021. Herrera slashed .284/.374/.405 with nine home runs and 47 RBI between the Low-A and High-A levels in 2019.

Shaw was designated for assignment Friday.

Shaw has essentially mastered Triple-A at this point, but the Giants seem to think he is a Quadruple-A hitter, as he has never been given much of a chance at the big-league level. He will offer organizational depth going forward if he goes unclaimed on waivers.

Alonso announced his retirement on his personal Instagram page Friday.

Alonso called it quits after failing to earn any big-league playing time in 2020. He'll finish his decade-long career with exactly 100 homers, 28 of which came during his uncharacteristically strong 2017 campaign for the Athletics and Mariners. He also spent time in the big leagues with the Reds, Padres, Indians, White Sox and Rockies, grabbing 872 hits while slashing .259/.332/.404.

Schwindel signed with the Athletics as a non-roster invitee Friday.

The 28-year-old was at the Tigers' alternate training site in 2020 after failing to make the Opening Day roster, and he'll now join the A's for spring training. Schwindel had a strong showing at Triple-A in 2019 with a .327/.361/.628 slash line and nine homers in 28 games.

Dixon was released by the Tigers on Thursday in order for him to head to Japan.

The Tigers did not announce which NPB club Dixon will be signing with. Dixon fits the typical profile of a player heading overseas, as he's a 28-year-old with a respectable 197 big-league games under his belt but a generally unimpressive showing in those games. He's hit 20 career homers at the highest level and owns a .228/.271/.410 slash line.

Voit (foot) is no longer experiencing pain after receiving a platelet-rich plasma injection in his foot, Brendan Kuty of The Newark Star-Ledger reports.

Voit doesn't expect his plantar fasciitis to be an issue during the upcoming season after seeing positive results from the PRP shot. This is great news for the Yankees, who will have their slugger back at full strength for the start of spring training.

Freeman was named the 2020 National League Most Valuable Player on Thursday.

Freeman is Atlanta's first MVP since 1999 as he received 28 of 30 first-place votes, while Mookie Betts received the other two votes and finished in second in the voting. Freeman appeared in all 60 games during the shortened 2020 season, slashing .341/.462/.640 with 13 home runs, 53 RBI, 45 walks and 37 strikeouts.

Castro's contract was selected by the Pirates on Friday.

Castro is best known for posting some pretty elite exit velocity readings in the lower levels by middle infielder standards. He hit 14 home runs in 61 games at Low-A in 2019 as a 20-year-old, which is quite the feat, but he fell flat after a promotion to High-A. Castro will likely open the year at High-A or Double-A and could reach the majors in 2022.

Boswell was added to the Rockies' 40-man roster Friday.

Boswell's production dipped at the Double-A level in 2019, but he was part of the team's 60-man roster in 2020. His addition to the 40-man roster will protect him from the upcoming Rule 5 draft.

Marcano was added to the Padres' 40-man roster Friday.

The move means Marcano won't be available for selection in the upcoming Rule 5 draft. It may have been a stretch for any team to select him, given that he's never played above Low-A, but the Padres evidently believe he has enough potential that they didn't want to take the risk.

Leyba was outrighted to Triple-A Reno by the Diamondbacks on Friday.

The 25-year-old missed the entirety of the 2020 campaign while serving an 80-game suspension after testing positive for PEDs, and he's now been removed from Arizona's 40-man roster. Leyba made his major-league debut in 2019 and went 7-for-25 with two doubles, a triple, six runs and five RBI.

Cano tested positive for a performance-enhancing drug Wednesday and will be suspended for the entire 2021 season, Jeff Passan of ESPN.com reports.

Cano was suspended while he was with the Mariners in 2018, and he'll now miss the entire 2021 season while also forfeiting his $24 million salary after testing positive for Stanozolol. With the 38-year-old sidelined, Jeff McNeil, Luis Guillorme and Andres Gimenez (oblique) could see increased time at second base for the Mets.

LeMahieu will decline the Yankees' one-year, $18.9 million qualifying offer for 2021 prior to Wednesday's deadline, Mark Feinsand of MLB.com reports.

The 32-year-old has been one of the best hitters in baseball for New York over the past two seasons with a .922 OPS, so it's not much of a surprise he'll be testing the open market in search of a longer-term deal. LeMahieu signed a two-year, $24 million deal with the Yankees in January 2019, and he should be able to exceed those figures this time around in free agency.

Jones was added to Cleveland's 40-man roster Friday.

Jones is one of Cleveland's top prospects, so it's not surprising to see him protected from the Rule 5 draft. The 22-year-old trained at the alternate training site in 2020, but he's yet to advance past the Double-A level. He hit .253 with eight home runs and 22 RBI with Double-A Akron in 2019.

Arias was added to Cleveland's 40-man roster Friday.

Arias was traded from San Diego to Cleveland at the end of August last year, and he'll unsurprisingly join the 40-man roster to protect him from the Rule 5 draft. The 20-year-old flashed his power at the High-A level in 2019, hitting .302 with 17 home runs and 75 RBI.

Welker was added to the Rockies' 40-man roster Friday.

Welker will unsurprisingly join the 40-man roster to protect him from the Rule 5 draft. The 23-year-old had a .721 OPS with 10 homers and 53 RBI in 2019 and was able to continue his development with the 60-man player pool last season.

Vosler signed a major-league deal with the Giants on Tuesday.

The 27-year-old spent the shortened season at the Padres' alternate training site and had a .291/.367/.523 slash line with 20 home runs and 63 RBI in 116 games at Triple-A in 2019. Vosler has yet to make his major-league debut, but he's now on the 40-man roster and would seem to stand a strong chance of cracking San Francisco's Opening Day roster next year.

Sanchez (Achilles) re-signed Thursday with the Nationals on a minor-league contract that includes an invitation to big-league spring training, Brittany Ghiroli of The Athletic reports.

A mainstay on the Washington bench from 2017 through 2019, Sanchez didn't see any action in 2020 after suffering a torn right Achilles' tendon in summer camp that required season-ending surgery. Though the Nationals haven't provided a clear timetable for his recovery, Sanchez's rehab program is expected to extend into the 2021 campaign. Once healthy, Sanchez will likely report to either Triple-A Fresno or Double-A Harrisburg.

Freeman elected free agency Saturday rather than accept an outright assignment to Triple-A Columbus.

Freeman filled a bench role for Cleveland during the abbreviated 2020 campaign, hitting a modest .237/.302/.316 in his 43 trips to the plate. That slash line looks a whole lot like his career .232/.315/.330 career marks, meaning the 33-year-old will almost certainly be searching for a minor-league deal this winter.

Maton was added to the Phillies' 40-man roster Friday, Meghan Montemurro of The Athletic reports.

Maton continued his development at the Phillies' alternate training site in 2020, and he'll now be protected from the Rule 5 draft as part of the 40-man roster. The 23-year-old advanced to Double-A Reading late in 2019, but he struggled a bit, hitting .210 with two home runs and 14 strikeouts over 62 at-bats.

Devers was added to the Marlins' 40-man roster Friday.

Devers was part of the Marlins' 60-man player pool in 2020, and he'll now be protected from the Rule 5 draft. The 20-year-old is one of the best defensive shortstops in the organization, but he'll need to demonstrate more production at the plate in 2021.

Vargas was added to Cleveland's 40-man roster Friday.

Vargas has yet to advance past the Rookie level, and the canceled minor-league season in 2020 didn't allow him to continue his development. He could spend the 2021 campaign with the Low-A or High-A club, and he'll now be protected from the upcoming Rule 5 draft.

Clement was added to Cleveland's 40-man roster Friday.

Clement advanced to Triple-A Columbus in 2019, and he spent the 2020 season at the alternate training site as part of the 60-man roster. He'll now be protected from the Rule 5 draft and could contend for a major-league roster spot in 2021.

Potts' contract was purchased by the Red Sox on Friday.

The headliner in the trade that sent Mitch Moreland to San Diego, Potts could have really used a traditional minor-league season to work on his approach against upper-level pitchers after struggling at Double-A in 2019 (93 wRC+, 28.6 percent strikeout rate). Even so, he just turned 22, so he wouldn't even be old for the level if he were sent back to Double-A at the start of the 2021 season. He still possesses plus right-handed pop and has a chance to handle third base.

Perdomo was added to the Diamondbacks' 40-man roster Friday.

Perdomo was part of Arizona's taxi squad in 2020, but he failed to make his major-league debut during the abbreviated season. As one of the team's top prospects, it's unsurprising to see him protected from the upcoming Rule 5 draft as part of the 40-man roster.

Arozarena was detained in Mexico on Tuesday following a domestic incident, Jeff Passan of ESPN.com reports.

Arozarena allegedly attempted to take his daughter away from her mother and assaulted the woman's father. MLB is investigating the matter and could potentially issue him a suspension under the league's domestic violence policy depending on its findings.

The Rays released O'Grady on Monday.

After being dropped from the Rays' 40-man roster Friday, O'Grady will now part ways with the organization entirely after going unclaimed off waivers. O'Grady saw limited action in a deep Rays outfield in 2020, appearing in only two games.

Osuna was released by the Pirates on Tuesday, Kevin Gorman of TribLive.com reports.

Osuna went unclaimed on waivers after being designated for assignment Friday. He's expected to sign with a team in Asia, which could be a good fit for a player whose career .241/.280/.430 slash line in 705 career big-league plate appearances isn't terrible but isn't good enough for a corner infielder or outfielder at the highest level.

Schebler signed a minor-league contract with the Angels on Saturday, Bob Nightengale of USA Today reports.

The deal will pay the outfielder $900,000 if he's able to earn a big-league job. Things haven't gone well for Schebler in recent seasons, as he received just a single plate appearance for the Braves in 2020 after hitting a miserable .123/.253/.222 in 95 trips to the plate for the Reds in 2019. He's still just 30 years old and owns a respectable enough 98 career wRC+ though, so there's at least a chance he turns things around and earns a bench spot.

Lee's contract was selected by the Royals on Friday.

In a system flush with pitching prospects, Lee is one of the better hitting prospects with any upper-level experience, so he was always going to get protected from the Rule 5 draft. He has the power and speed to be a fantasy asset some day, but he needs to increase his launch angle and improve his approach.

Canario's (shoulder) contract was purchased by the Giants on Friday.

Canario getting protected from the Rule 5 draft was a forgone conclusion, but the bigger news is that he is recovering from mid-November surgery to repair a torn labrum and dislocated left shoulder. He may not be available for the start of the season and his production could be negatively affected when he initially returns. That said, few players in the minors have as much power potential as Canario, so his future remains bright as long as he can cut down on the strikeouts.

Morton agreed Tuesday with the Braves on a one-year, $15 million contract, Mark Feinsand of MLB.com reports.

As the 37-year-old prepares for what could be his final season in the big leagues, he'll return to the organization that originally drafted him back in 2002. While Morton never found success at the MLB level during his time in Atlanta, he's quietly emerged as one of baseball's more reliable starters over the back nine of his career, submitting sub-4.00 ERAs and sub-1.20 WHIPs in three of the past four seasons. While missing time with a shoulder injury in the pandemic-shortened 2020 campaign, Morton finished with a 4.74 ERA and 1.39 WHIP across 38 innings, but the underlying peripherals (18.8 K-BB%, 0.9 HR/9, 3.89 xERA) were generally encouraging. After having his $15 million club option declined by the Rays earlier this offseason, Morton will end up taking home the same payday while he moves on to Atlanta.

Martinez (oblique) was not arrested Monday for violating social-distancing protocols in the Dominican Republic, contrary to previous reports, Anne Rogers of MLB.com reports.

Initial reports indicating that Martinez would be facing legal trouble for hosting a large gathering in violation of the country's COVID-19 protocols, but both the pitcher's agent and the Cardinals denied those allegations. He does appear to have taken part in the event but is not facing any charges. The incident appears to have disappointed his team, which put out a statement which reads, in part, "Certainly, we would not condone anyone from our organization knowingly violating community laws or health regulations," but he doesn't appear to be facing any long-term consequences.

Martinez (oblique) was taken into custody Monday by National Dominican Police in Puerto Plata, Dominican Republic for violating the country's social-distancing protocols, Hector Gomez of Deportivo Z 100 reports.

Martinez returned to his native country for the offseason following an injury-shortened 2020 campaign in which he posted a 9.90 ERA and 2.10 ERA over his five starts. The 29-year-old isn't expected to face any punishment from MLB for his arrest, but he'll presumably still have to resolve the legal issue before he's cleared to return to North America for spring training. The Cardinals haven't decided whether Martinez will continue to work as a starter in 2021 or prepare for a move back to the bullpen.

File was added to the Brewers' 40-man roster Friday.

File continued his development at the Brewers' alternate training site in Appleton during the 2020 season, and he'll now be protected from the Rule 5 draft. The right-hander posted a 2.79 ERA and 1.11 WHIP over 80.2 innings with Double-A Biloxi in 2019, and he could make his major-league debut at some point in 2021.

Solis was added to the Astros' 40-man roster Friday, Jake Kaplan of The Athletic reports.

One of Houston's most talented prospects, Solis missed the 2019 season after undergoing Tommy John surgery but he shouldn't be overlooked in dynasty leagues. Prior to the injury, Solis' fastball projected as a 70-grade pitch and he also has a plus curveball. He could shoot up rankings if he impresses early in 2021, likely at High-A or Double-A.

Whitley (arm) was added to the Astros' 40-man roster Friday, Jake Kaplan of The Athletic reports.

General manager James Click told Chandler Rome of the Houston Chronicle that Whitley has been working out and the team expects him to be healthy for the start of spring training, but as with any pitcher who ended the season with an arm injury, we should wait until he is throwing in spring games before taking that as gospel. Whitley was an obvious player to protect from the Rule 5 draft, but he is coming off a pretty disappointing season, as he was looking as good as he has in years before coming down with an arm injury early at the alternate training site. Health permitting, this could be the year that he finally makes his big-league debut.

The Padres released Perdomo (elbow) on Monday.

Perdomo is set to miss the entire 2021 season while recovering from Tommy John surgery. Once healthy, the 27-year-old will likely have to settle for a minor-league contract with another organization.

The Diamondbacks released Guerra on Monday.

Guerra's release came three days after the Diamondbacks cast him off their 40-man roster. As he heads to free agency, Guerra will likely be in the market for a one-year deal or a minor-league contract after posting a 3.04 ERA, 1.35 WHIP and 21:15 K:BB in 23.2 innings with Arizona in 2020.

Law announced Monday via his personal Twitter account that he agreed to a minor-league contract with the Twins that includes an invitation to big-league spring training.

According to Darren Wolfson of Channel 5 Saint Paul, Law's deal is worth $750,000 at the big-league level and contains an opt-out clause. Law didn't receive a call-up to the majors at any point in 2020 after being included in the Rangers' 60-man player pool, but the reliever made 58 appearances for the Blue Jays in 2019, compiling a 4.90 ERA and 1.66 WHIP.

Sparkman (forearm) was released by Kansas City on Monday.

Sparkman was designated for assignment Friday, and he'll hit the open market after the Royals requested unconditional release waivers. He appeared in just four games in 2020, surrendering three runs on nine hits and a walk over five innings of work. Sparkman ended the year on the shelf with a strained forearm, which is likely the primary reason the Royals decided to move on.

Tillo (elbow) was added to the 40-man roster Friday, Jeffrey Flanagan of MLB.com reports.

With Tillo likely to miss the entire 2021 season recovering from August 2020 Tommy John surgery, he will be easy to stash on the 60-day injured list now that he is on the 40-man roster. The Royals think the left-handed Tillo could be electric in a bullpen role as early as 2022.

Adams was outrighted to Triple-A Omaha on Friday.

Adams made six relief appearances during his first season with the Royals in 2020, but he was inefficient once again, allowing nine earned runs on 15 hits and no walks while striking out six over 8.2 innings. He'll be cast off the 40-man roster to make room for several prospects who will be protected from the Rule 5 draft.

The Orioles released Nunez on Monday after he cleared waivers.

Since Nunez was arbitration-eligible for the first time in his career and would have been due a hefty salary increase, the Orioles opted to cut ties with the 26-year-old and reserve his 40-man roster spot for another player. After slugging 43 home runs across the past two seasons, Nunez could find a home elsewhere as a bench bat or designated hitter option.

Nunez was designated for assignment Friday, Joe Trezza of MLB.com reports.

While Nunez offers fantasy value when he is playing every day, the rebuilding Orioles would prefer to use his 40-man roster spot to protect prospects from the Rule 5 draft. Nunez is a first baseman/designated hitter, so his real-life value is minimal. He was worth 0.9 fWAR in 203 games over the past two seasons.

Mayfield was claimed off waivers by the Braves on Friday.

The 30-year-old was designated for assignment by the Astros earlier in the week, and the Braves opted to scoop him up off waivers. Mayfield appeared in 47 games over the past two seasons and had a .170/.198/.283 slash line with two homers and 30 strikeouts in 112 plate appearances.

Ohtani has been throwing for approximately a month and has reached 120 feet, Jeff Fletcher of The Orange County Register reports.

Ohtani remains somewhat limited but has been able to throw at 75 to 80 percent effort. The Angels expect him to enter spring training as a two-way player. Of course, he was expected to be a two-way player this year as well, but he wound up allowing seven runs while recording just five outs over a pair of starts before the Angels shut him down from throwing. The team will hope that putting his Tommy John surgery another year in the rearview mirror and going through a normal offseason and spring buildup process will bring different results this time around.

Martinez will not opt out of the remaining two years on his contract with the Red Sox, Jon Heyman of MLB Network reports.

This seemed like a forgone conclusion, especially with Martinez coming off a down year. He is due $38.75 million over the next two years. The designated hitter, who turned 33 in August, slashed .213/.291/.389 with seven home runs in 54 games this season.

Cron will play the 2021 season in Nippon Professional Baseball in Japan, Nick Piecoro of the Arizona Republic reports.

Cron was released by the Diamondbacks on Friday after struggling over his first two seasons in the majors, and his rights were apparently sold to a club in Japan. While it's unclear what team he'll play for in the NPB, the 27-year-old will attempt to turn things around overseas in 2021.
