Mac Williamson: Headed to KBO
by RotoWire Staff | RotoWire

Williamson is nearing an agreement to sign with the Samsung Lions of the Korea Baseball Organization, Sung Min Kim of The Athletic reports.

WIlliamson's rights remain with the Mariners after he recently accepted an outright assignment to Triple-A Tacoma, but he'll likely be released from his obligations to the organization while he pursues what's presumably a more lucrative opportunity overseas. The 29-year-old Williamson has posted some eye-popping numbers in the Triple-A ranks over the past three seasons, but his 28.8 percent career strikeout rate has prevented him from finding much sustained success in the majors. He could emerge as one of the KBO's top power hitters while having the luxury of teeing off against pitchers who typically work at lower velocities than their MLB counterparts.

Mariners' Mac Williamson: Outrighted to Triple-A
by RotoWire Staff | RotoWire

Williamson was sent outright to Triple-A Tacoma on Wednesday, Greg Johns of MLB.com reports.

Williamson will remain in Seattle's organization after being designated for assignment by the Mariners and subsequently passing through waivers unclaimed. The outfielder is slashing just .156/.250/.258 with four home runs and two stolen bases in 144 big-league plate appearances this season.

Mariners' Mac Williamson: DFA'd by Seattle
by RotoWire Staff | RotoWire

Williamson was designated for assignment by the Mariners on Tuesday.

Williamson hasn't found his stroke at the dish since being called up June 5, hitting just .182 with three homers and 10 RBI over 25 games. He'll head to the waiver wire after getting booted from the 40-man roster.

Mariners' Mac Williamson: Playing time slips
by RotoWire Staff | RotoWire

Williamson is out of the lineup for Sunday's game against the Astros, Greg Johns of MLB.com reports.

Williamson will head to the bench for the third time in four games in favor of Dylan Moore, who may have temporarily displaced Williamson as manager Scott Servais' preferred option in left field. Though Williamson joined the big club with a bang in his first game following his June 5 callup from Triple-A Tacoma, slugging a three-run, pinch-hit homer, he's managed a .197/.303/.288 slash line in his subsequent 19 contests.

Mariners' Mac Williamson: Another productive start
by RotoWire Staff | RotoWire

Williamson went 1-for-3 with an RBI double play, a two-run home run and three runs overall in a win over the Orioles on Sunday.

Williamson's tenure as a fill-in for Mitch Haniger (groin) continues to be a productive one, with the veteran outfielder now having driven in five runs over his last four games. Williamson also boasts a seven-game hitting streak, a stretch during which he's slugged a pair of round trippers overall. While Haniger's eventual return will relegate Williamson to a bench role, he's currently paying off to an extent for those who plucked him off the wire in their leagues.

Mariners' Mac Williamson: Swats solo homer
by RotoWire Staff | RotoWire

Williamson went 1-for-5 with a solo home run in Friday's 10-9 win over the Orioles.

Williamson has hit safely in his last five games, going 5-for-19 in that span. The left fielder has hit only .204 with two homers and seven RBI in 14 games since signing with the Mariners after posting a .118 average in 15 games with the Giants earlier in the season. Williamson should continue to see regular playing time with Mitch Haniger (groin) out.

June 15, 2019 01:16 PM
Mariners' Mac Williamson: Productive from bottom of order
by RotoWire Staff | RotoWire

Williamson went 2-for-4 with a run in a win over the Athletics on Friday.

Williamson drew the start in left field and offered solid production out of the last spot in the order, posting his first multi-hit effort since arriving in Seattle earlier in June. The 28-year-old continues to log regular playing time for the time being while Mitch Haniger (groin) and Braden Bishop (chest) remain on the injured list.

Mariners' Mac Williamson: Retreats to bench
by RotoWire Staff | RotoWire

Williamson is not in the lineup Wednesday against the Twins, Greg Johns of MLB.com reports.

Williamson has started four straight games since Mitch Haniger (groin) landed on the IL, going 2-for-16 with a 37.5 percent strikeout rate in those contests. Three of those starts came against left-handed pitchers, and with Shed Long starting in left field and hitting eighth against right-hander Jose Berrios on Wednesday, it appears Williamson could be headed toward the short side of a platoon.

June 9, 2019 04:00 PM
Mariners' Mac Williamson: Gets third straight start
by RotoWire Staff | RotoWire

Williamson will start in left field and bat eighth Sunday against the Angels.

Williamson will be making his third straight start and looks like he could be in line for a full-time role while Mitch Haniger (groin) and Braden Bishop (chest) are on the 10-day injured list. The 28-year-old already showcased some power potential by slugging a three-run home run in his first plate appearance with the team Wednesday, but making consistent contact has proven to be a more elusive skill for Williamson over parts of five seasons in the majors. With a 28.6 percent career strikeout rate and a 56.1 percent career groundball rate, Williamson profiles as a major risk in the batting-average category.

Mariners' Mac Williamson: Homers in debut
by RotoWire Staff | RotoWire

Williamson launched a solo home run in his only at-bat during Wednesday's 14-1 win over the Astros.

Williamson came out with a bang in his Mariners debut by swatting a home run off Brady Rogers in the eighth inning as a pinch hitter for Daniel Vogelbach. The outfielder had just signed a minor-league contract prior to the game and got called up immediately after Braden Bishop landed on the injured list with a lacerated spleen. Williamson played 15 games for the Giants earlier this season and batted just .115 before getting released. However, his Mariners tenure could hardly have gotten off to a better start.

Mariners' Mac Williamson: Contract selected by Mariners
by RotoWire Staff | RotoWire

Williamson had his contract selected from Triple-A Tacoma by the Mariners on Wednesday, Ryan Divish of The Seattle Times reports.

Williamson signed a minor-league deal with the Mariners earlier Wednesday and didn't have to wait long before moving to the majors with Braden Bishop (spleen) landing on the injured list. Williamson struggled during his 15-game stint with the Giants earlier this season, slashing .118/.211/.196 with a 31.6 percent strikeout rate in 57 plate appearances.

June 1, 2019 02:56 PM
Mac Williamson: Elects free agency
by RotoWire Staff | RotoWire

Williamson cleared waivers Saturday and elected free agency, Maria I. Guardado of MLB.com reports.

Williamson has appeared in 135 games over his five-year big-league career, hitting an unimpressive .207/.283/.359. He'll almost certainly be looking for a minor-league contract.

May 25, 2019 02:20 PM
Giants' Mac Williamson: DFA'd again
by RotoWire Staff | RotoWire

Williamson was designated for assignment for the second time this year Saturday.

Williamson went unclaimed when he was DFA'd at the end of spring training, and there's a good chance the same thing happens this time around, as his poor showing in 15 games for the Giants brought the 28-year-old's career slash line down to .207/.283/.359 over parts of five seasons. Mike Yastrzemski's contract was selected in a corresponding move.

Giants' Mac Williamson: Strikes out five times
by RotoWire Staff | RotoWire

Williamson went 0-for-5 with five strikeouts in Thursday's 5-4 loss to Atlanta.

Williamson's line may end up being one of the worst single-game performances of the 2019 season. The 28-year-old is struggling to hit major-league pitching yet again, slashing .128/.226/.213 through 14 games after crushing Triple-A pitching (.378/.459/.756). The Giants have been playing Williamson regularly since his callup, but he is in danger of losing playing time to platoon bat Tyler Austin, who homered for the second time in as many days Thursday.

Giants' Mac Williamson: Out of lineup
by RotoWire Staff | RotoWire

Williamson is not in the lineup Tuesday against Atlanta, Henry Schulman of the San Francisco Chronicle reports.

Williamson had started 11 straight games after getting called up in early May but hit just .154/.250/.256 over that stretch. Stephen Vogt gets the start in left field.

May 15, 2019 06:44 PM
Giants' Mac Williamson: Doubles in loss
by RotoWire Staff | RotoWire

Williamson went 2-for-3 with a walk, a double and an RBI in Tuesday's 7-3 loss to the Blue Jays.

Williamson finally turned in a solid fantasy day after going 1-for-17 following his 2019 debut home run. It has been a small sample, but the 28-year-old seems like the same hitter we have seen in previous seasons; a powerful slugger who will strike out more than he provides hits. Williamson does appear to have an everyday job, and that alone can keep him relevant in deeper formats, especially for owners who need a boost in power.

Giants' Mac Williamson: Homers in big-league return
by RotoWire Staff | RotoWire

Williamson went 2-for-4 with a walk, a home run, two runs scored and four RBI in Tuesday's 14-4 rout of the Rockies.

There's no better ballpark in which to make an impressive return to a big-league lineup than Coors Field, and Williamson took full advantage. The 28-year-old was tearing up the PCL prior to his promotion, slashing .378/.459/.756 with nine homers in 23 games for Triple-A Sacramento, and he should get a long leash in left field for the Giants.

May 7, 2019 05:40 PM
Giants' Mac Williamson: Starting in left field
by RotoWire Staff | RotoWire

Williamson will start in left field and bat sixth Tuesday night against the Rockies, Kyle Newman of The Denver Post reports.

Williamson had his contract selected from Triple-A Sacramento earlier in the day, and he'll be immediately forced into duty. He hit .378 with nine homers and 22 RBI over 23 games with the River Cats before getting the call.

May 7, 2019 10:12 AM
Giants' Mac Williamson: Will get call to majors
by RotoWire Staff | RotoWire

The Giants plan to select Williamson's contract from Triple-A Sacramento ahead of Tuesday's game against the Rockies, Alex Pavlovic of NBC Sports Bay Area reports.

Williamson was designated for assignment coming out of spring training after the Giants elected to enter the regular season with Gerardo Parra, Connor Joe and Michael Reed as their corner-outfield options. All three players have since been removed from the 40-man roster, while Williamson has earned his way back onto it on the strength of his stellar power production in the Pacific Coast League. After slugging three more home runs Monday in Sacramento's 12-6 win over Reno, Williamson is sporting a .378/.459/.756 slash line across 98 plate appearances. With Mike Gerber offering little impact as the Giants' primary left fielder, Williamson could unseat him for a full-time role right away and may make for an appealing option in DFS and leagues with daily moves as San Francisco begins a three-game set at Coors Field.

April 4, 2019 06:56 PM
Giants' Mac Williamson: Clears waivers
by RotoWire Staff | RotoWire

Williamson cleared waivers and will report to Triple-A Sacramento, Ken Rosenthal of The Athletic reports.

Williamson will stick in the Giants organization after passing through waivers untouched. The 28-year-old outfielder owns a career .222/.295/.386 line across parts of four big-league campaigns (120 games).
