Rockies' Jairo Diaz: Poised for high-leverage role
by RotoWire Staff | RotoWire

Diaz made four Cactus League appearances and allowed one run on four hits with one strikeout and one walk over four innings before the suspension of spring training.

The 28-year-old made his return to the majors in 2019 and recorded five saves and seven holds while posting a 3.69 FIP in 56 outings for Colorado. Diaz and Carlos Estevez are in line to work as two of the Rockies' top bullpen options behind Scott Oberg and closer Wade Davis once play resumes, per Thomas Harding of

Rockies' Jairo Diaz: Earns extra-inning win
by RotoWire Staff | RotoWire

Diaz (6-4) tossed a perfect 10th inning and earned the win in Saturday's 3-2 triumph over the Brewers.

Diaz did his part in the top of the tenth, and Trevor Story made him a winner with a walkoff homer. Diaz owns a 4.53 ERA and 1.30 WHIP with five saves and seven holds in 57.2 innings this year.

Rockies' Jairo Diaz: Perfect inning for fifth save
by RotoWire Staff | RotoWire

Diaz pitched a perfect ninth inning, striking out two, to earn his fifth save of the season in Saturday's 4-2 win over the Dodgers.

Diaz was tasked with protecting a two-run lead, and he made no mistakes in doing so. It was a strong bounce-back effort after he allowed four runs in a blown save versus the Mets on Wednesday. For the season, Diaz has posted a 4.42 ERA and 1.30 WHIP in 53 innings.

Rockies' Jairo Diaz: Nabs fourth save
by RotoWire Staff | RotoWire

Diaz gave up a hit and struck out one in a scoreless ninth inning Friday to record his fourth save of the season in a 10-8 win over the Padres.

The right-hander has settled in nicely as the Rockies' new closer, posting a 0.00 ERA, 0.91 WHIP and 7:1 K:BB through 7.2 innings in September while converting all four of his save opportunities. Wade Davis has one more season left on his contract and Scott Oberg should be healthy next spring, but Diaz and his 97 mph fastball will continue to get a head start on staking his claim to the role in 2020 down the stretch.

Rockies' Jairo Diaz: Records third save
by RotoWire Staff | RotoWire

Diaz earned the save against the Cardinals on Wednesday, firing a scoreless ninth inning while allowing one hit and striking out one.

Diaz entered the ninth inning tasked with protecting a 2-1 lead. After giving up a leadoff single to Paul DeJong, Yadier Molina reached first on a throwing error by Nolan Arenado. Diaz then induced a double play, allowing DeJong to advance to third. The threat extended when Diaz issued a free pass to Matt Carpenter, but luckily, he finished things off for good by forcing Rangel Ravelo to line out. The save was the third of the year for the right-hander, who owns a 4.01 ERA and 1.26 WHIP across 49 appearances. Diaz should continue to garner save opportunities as part of Colorado's closer committee.

Rockies' Jairo Diaz: Picks up second save
by RotoWire Staff | RotoWire

Diaz picked up the save against the Cardinals on Tuesday, tossing two scoreless innings to close out Colorado's 2-1 victory. He struck out two and walked none.

It was the second save of the season for the right-hander, who needed 21 pitches over two innings to successfully protect a one-run advantage. He figures to continue to see rotational save opportunities in Colorado's committee setup, and has a 4.10 ERA, 1.24 WHIP and 57:14 K:BB across 48.1 innings in 2019.

Rockies' Jairo Diaz: Earns first save
by RotoWire Staff | RotoWire

Diaz picked up the save against the Padres on Friday after tossing a scoreless ninth frame with one strikeout.

Summoned to protect a 3-2 lead in the ninth, Diaz did so in order to pick up his first major-league save. The right-hander, who was promoted back in May, has worked his way up the depth chart into higher-leverage situations. He should continue to see save opportunities as part of Colorado's closer committee. Through 46 appearances, Diaz owns a 4.37 ERA and 1.28 WHIP.

Rockies' Jairo Diaz: Earns victory against blown save
by RotoWire Staff | RotoWire

Diaz (5-3) earned the win against the Braves on Monday despite also being charged with a blown save, allowing one run on one hit and a walk with two strikeouts in the ninth inning.

Diaz struck out the first hitter he faced but then yielded a triple to one of the newest Braves, Francisco Cervelli. A pinch runner scored on a sacrifice fly a couple batters later. Diaz finished the frame and then got the victory after the Rockies won with a walk-off homer, but this doesn't bode well for Diaz continuing to receive save chances in the future. He has yet to earn a save and has blown two chances with a 4.75 ERA, 1.32 WHIP and 50 strikeouts in 41.2 innings this season.

Rockies' Jairo Diaz: Will get look in save situations
by RotoWire Staff | RotoWire

Manager Bud Black said Monday that he's not ready to anoint a new closer, but he made it clear that Diaz and Carlos Estevez will see save chances over the remainder of the season, Patrick Saunders of the Denver Post reports.

Scott Oberg landed on the IL on Sunday with a blood clot in his right arm and will miss the rest of the season. It was Estevez who cleaned up for Wade Davis later in the day Sunday, going two scoreless innings for the win after Davis blew the save chance. Estevez now has a 3.97 ERA and 67:21 K:BB in 56.2 innings following that outing, but Diaz also throws 97 mph with his fastball, and Diaz has been making quite an impression on the field of late with only two earned runs allowed and a 13:1 K:BB in August (2.16 ERA). It remains to be seen who will emerge as the primary option.

Rockies' Jairo Diaz: Collects fourth win
by RotoWire Staff | RotoWire

Diaz (4-2) pitched two scoreless innings Friday, allowing just one hit while striking out three to earn the win in a 5-4 win over the Giants.

He became the pitcher of record when Ian Desmond hit a go-ahead double in the seventh inning. Diaz has now tossed five consecutive scoreless innings since imploding for five runs in two-thirds of an inning versus the Nationals on July 23. The right-hander has a 5.13 ERA and 1.35 WHIP in 33.1 innings overall this season, but 25 of his 34 appearances have been scoreless and 10 of his 19 runs allowed have come in just two outings.

Rockies' Jairo Diaz: Picks up relief win
by RotoWire Staff | RotoWire

Diaz (2-2) allowed two hits and struck out two in a scoreless eighth inning Friday, earning the win in a 3-2 victory over the Reds.

Diaz became the pitcher of record when David Dahl and Daniel Murphy hit solo home runs in the bottom of the eighth to put the Rockies ahead. Diaz has allowed three runs on 10 hits and four walks over his last 7.1 innings while striking out 11 in that span. The right-hander has a 4.94 ERA and 1.31 WHIP with 26 strikeouts through 23.2 innings for the season.

Rockies' Jairo Diaz: Takes second loss
by RotoWire Staff | RotoWire

Diaz (1-2) allowed two runs on a hit and a walk in two-thirds of an inning, taking the loss Friday as the Rockies fell 4-2 to the Dodgers.

Diaz struck out Enrique Hernandez and got Cody Bellinger to ground out to begin his appearance, but things fell apart when the right-hander walked Max Muncy and then allowed a walkoff homer to Matt Beaty. It's Diaz's second loss in the last week, and he now has a 5.51 ERA and 1.04 WHIP through 16.1 innings.

Rockies' Jairo Diaz: Charged with loss in relief
by RotoWire Staff | RotoWire

Diaz (1-1) was charged with the loss Friday against the Padres after surrendering five runs on five hits with no walks or strikeouts in one inning.

Diaz came into the 12th inning with the score tied, 11-11. Unfortunately, he did little to keep the Rockies in the game as the Padres lit him up for five runs, including a 432-foot, two-run homer to Hunter Renfroe. Diaz has a 5.40 ERA, 1.05 WHIP and 14:2 K:BB this season.

Rockies' Jairo Diaz: Climbing bullpen depth chart
by RotoWire Staff | RotoWire

Diaz struck out two as part of a perfect seventh inning in Monday's 6-5 win over the Cubs.

After missing two of the previous three seasons with serious arm injuries, Diaz was forced to settle on a minor-league with Colorado in January. The right-hander dazzled early in the campaign at Triple-A Albuquerque to earn a promotion to Colorado in May and has continued to dominate, gaining the trust of manager Bud Black in the process. Summoned Monday late in a 4-4 ballgame, Diaz needed only nine pitches to retire the side. With only two runs allowed to go with a 13:2 K:BB and three holds over his 10.1 innings with the Rockies, Diaz looks to have emerged as one of the top candidates to close in the event Wade Davis requires another trip to the injured list at any point.

Rockies' Jairo Diaz: Earns first career win
by RotoWire Staff | RotoWire

Diaz (1-0) pitched a perfect seventh inning to earn the win in Tuesday's 6-2 win over the Diamondbacks.

After giving up runs in each of his last two appearances, Diaz was able to maintain a 2-2 tie in the top half of the seventh inning before catcher Chris Iannetta knocked a two-run homer in the bottom of the frame. Diaz is up with the Rockies in place of Wade Davis (oblique), and the 28-year-old has a 3.86 ERA and four strikeouts over 4.2 innings so far.

May 22, 2019 03:52 PM
Rockies' Jairo Diaz: Promoted to majors
by RotoWire Staff | RotoWire

Diaz was recalled from Triple-A Albuquerque on Wednesday, Patrick Saunders of The Denver Post reports.

With Wade Davis (oblique) landing on the injured list, Diaz's contract was selected from Triple-A to take the vacancy in the bullpen. The hard-throwing righty had given up one earned run while striking out 22 in 20 innings for the Isotopes, logging six saves over that stretch. The big-league saves will likely go to a more experienced reliever, but Diaz is a reliever to keep an eye on in dynasty leagues.

Rockies' Jairo Diaz: Records save Monday
by RotoWire Staff | RotoWire

Diaz (forearm) picked up the save Monday against the Reds after firing a scoreless inning of relief. He struck out one and allowed one hit.

Diaz isn't in big-league camp; he joined the Rockies for Monday's exhibition simply to provide an additional arm out of the bullpen. It's encouraging to see the 27-year-old back to full health after a forearm injury limited him to just 12.1 minor-league innings last season.

January 3, 2019 11:56 PM
Rockies' Jairo Diaz: Returns to Rockies
by RotoWire Staff | RotoWire

Diaz (forearm) returned to the Rockies on a minor-league deal Wednesday, the Denver Post reports.

Diaz has 29.2 major-league innings and a 3.64 ERA to his name, but a forearm issue limited him to just 12.1 minor-league innings last season. He reportedly hasn't been extended an invitation to big-league spring training.

June 18, 2018 06:00 PM
Rockies' Jairo Diaz: Re-signs with Rockies
by RotoWire Staff | RotoWire

Diaz (forearm) signed a minor-league contract with the Rockies on Monday, Nick Groke of The Athletic Denver reports.

Diaz has linked back up with the Rockies after being cut loose by the team last week. The right-hander has been sidelined since April with a forearm injury, but he isn't expected to be out much longer. Prior to suffering the injury, Diaz compiled a 9.82 ERA across 3.2 innings with Triple-A Albuquerque, where he figures to report once healthy.

June 13, 2018 02:28 PM
Jairo Diaz: Released by Colorado
by RotoWire Staff | RotoWire

The Rockies released Diaz (forearm) on Tuesday.

The Rockies were unable to find a trade partner for Diaz and the right-hander apparently wasn't keen on accepting an assignment to Triple-A Albuquerque, so he'll depart the organization in pursuit of an opportunity elsewhere. Diaz has been sidelined since mid-April with a sore right forearm, but recent reports suggested that the injury isn't anything that will likely sideline him for much longer. Assuming other teams are comfortable with where he's at on the health front, Diaz shouldn't have to wait long before landing a minor-league deal.
