Rockies' Jairo Diaz: Clears waivers
by RotoWire Staff | RotoWire

Diaz cleared waivers and was outrighted to Colorado's alternate training site Monday.

Diaz failed to draw interest on waivers after being designated for assignment Thursday. He'll aim to stay sharp at Colorado's alternate training site until called upon by the big-league club.

Rockies' Jairo Diaz: Designated for assignment
by RotoWire Staff | RotoWire

Diaz was designated for assignment by the Rockies on Thursday, Patrick Saunders of The Denver Post reports.

The Rockies officially signed right-hander Jhoulys Chacin to a major-league contract Thursday, and Diaz was removed from the 40-man roster in a corresponding move. Diaz posted a 10.24 ERA and 2.17 WHIP in 9.2 innings during nine relief appearances this spring and will likely report to the team's alternate training site if he goes unclaimed on waivers.

Rockies' Jairo Diaz: Tosses scoreless frame
by RotoWire Staff | RotoWire

Diaz allowed two hits and no walks while striking out one over one scoreless inning in Saturday's spring loss to the White Sox.

Diaz allowed three runs during his last outing, but he was able to keep the White Sox in check during the fourth inning Saturday. The right-hander has posted a 10.24 ERA and 2.17 WHIP over 9.2 relief innings this spring. Diaz has recorded nine saves across the past two seasons but should serve as a setup man and late reliever in lower-leverage situations to begin the 2021 campaign.

Rockies' Jairo Diaz: Avoids arbitration with Colorado
by RotoWire Staff | RotoWire

Diaz agreed to a one-year contract to avoid arbitration with the Rockies on Tuesday, Mark Feinsand of reports.

The 29-year-old had a chance to secure the closer's role in 2020 and picked up three saves with a 1.35 ERA in his first seven appearances, but he posted a 10.80 ERA in 17 games the rest of the season. Still, Colorado decided to give the right-hander the chance to get back on track in 2021, avoiding arbitration in the process.

Rockies' Jairo Diaz: Rough campaign continues
by RotoWire Staff | RotoWire

Diaz (1-2) took the loss against the Giants on Tuesday, allowing three runs on three hits while registering only one out (via strikeout).

Diaz entered the contest in a 2-2 tie and immediately allowed the Giants to take the lead on an Alex Dickerson homer. The right-hander allowed two more hits prior to being pulled, and both runners came around to score after Diaz departed the game. Diaz had logged five straight scoreless appearances but still owns an unsightly 8.50 ERA on the campaign.

Rockies' Jairo Diaz: Hit hard by Giants
by RotoWire Staff | RotoWire

Diaz retired two hitters -- both via strikeout -- and surrendered seven runs on six hits and a walk Tuesday in the Rockies' 23-5 loss to the Giants.

After beginning August with three saves in as many appearances to emerge as the Rockies' preferred closing option, Diaz has been on a downward slide ever since. Not only has Diaz failed to pick up a save in his subsequent nine appearances, but he's torched his fantasy managers' ratios with a 17.55 ERA and 3.90 WHIP over 6.2 innings. It's safe to say that Diaz won't re-enter the Colorado closing picture anytime soon, with the likes of Daniel Bard, Carlos Estevez and the newly acquired Mychal Givens all representing better bets for saves at this point.

Rockies' Jairo Diaz: Earns win in relief
by RotoWire Staff | RotoWire

Diaz (1-1) earned the win Tuesday against the Diamondbacks after pitching a scoreless inning, allowing one hit and fanning one.

Diaz entered the game in the bottom of the sixth and allowed a leadoff double to Nick Ahmed, but he settled down afterward and retired Jon Jay, Carson Kelly and Kole Calhoun in order to complete his fifth straight scoreless inning. Diaz might have lost the ninth-inning role earlier this month, but he still owns a respectable 2.45 ERA in 13 appearances this season.

Rockies' Jairo Diaz: Loses hold on ninth-inning duties
by RotoWire Staff | RotoWire

Diaz allowed two runs (zero earned) on one hit and three walks while striking out one over 0.2 innings in Sunday's win against the Rangers. He didn't factor into the decision.

Even with the Rockies holding a comfortable 10-4 lead in the ninth inning, Diaz was called on to finish the game in Colorado. However, he struggled mightily with command, walking in two runs while only 12 of his 27 pitches went for strikes. He was unable to record the final out as he was pulled with the bases loaded and two outs in the final inning. Manager Bud Black said after the game that the Rockies won't use a "designated closer" role for now after Diaz's rough outing, Patrick Saunders of The Denver Post reports. While Diaz could still be used in some save situations, the uncertainty significantly hinders his fantasy value. Daniel Bard could be a strong candidate to handle ninth-inning duties in the coming games.

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

Diaz allowed one hit and one walk but pitched 1.1 innings to earn the save Thursday against the Giants.

Diaz was brought in with two outs in the eighth inning after the Giants scored a run to bring the Rockies' lead to 6-4. He walked the first batter he faced, but induced a groundout to close the frame. Diaz remained in the game for the ninth inning, and closed out the game with little drama. Diaz has now recorded three of the team's last four saves, and appears to be in line to continue to see save opportunities.

Rockies' Jairo Diaz: Records save in shaky outing
by RotoWire Staff | RotoWire

Diaz allowed two runs (one earned) on two hits Monday, earning a save in the win over the Giants.

After Diaz allowed a run on a sacrifice fly, the Giants scored a second run after a wild pitch and later a throwing error by Ryan McMahon. With Wade Davis (shoulder) stashed on the injured list, Diaz has now notched a save in two straight games.

Rockies' Jairo Diaz: Gets one-out save
by RotoWire Staff | RotoWire

Diaz was called upon to get the last out Sunday against the Padres while protecting a three-run lead with a runner on second, and he got the save on one pitch, retiring Manny Machado on a flyout to get the save.

Diaz was already the leading candidate to take the closing role, with both Wade Davis and Scott Oberg on the IL. Carlos Estevez began the ninth inning, but first entered the game with two outs in the eighth and the score 9-2, and promptly allowed a bases clearing triple, so this wasn't a save situation for Estevez. The contrast in results bodes well for Diaz.

Rockies' Jairo Diaz: Top candidate to close
by RotoWire Staff | RotoWire

Diaz is among the top candidates to step in as the Rockies' closer after Wade Davis (shoulder) was placed on the 10-day injured list and Scott Oberg (arm) was placed on the 45-day injured list Sunday, Thomas Harding of reports.

Oberg will likely be out for the season after developing a blood clot on his right arm, while Davis' timeline to return is more uncertain as he battles through a right shoulder strain. While manager Bud Black is unlikely to formally name a new closer and could even opt to play matchups in the ninth inning, Diaz probably represents the best of the team's relief options from a skills standpoint. Blessed with a mid-to-high-90s fastball, Diaz has already filled a key late-inning role for the Rockies, collecting three holds while striking out seven over four scoreless innings entering Sunday's series finale with the Padres. Carlos Estevez could also garner a look in save scenarios, while James Pazos could also see late-inning action against lefty-heavy lineups.

Rockies' Jairo Diaz: Makes summer camp debut
by RotoWire Staff | RotoWire

Diaz (undisclosed) made his first appearance in an intrasquad game Saturday, Thomas Harding of reports.

Diaz gave up a double to David Dahl and induced a soft popout from Trevor Story in the relief outing. Per Nick Groke of The Athletic, Diaz didn't report to the Rockies' summer camp until July 10 after being delayed by a week due to what manager Bud Black said were travel issues. Diaz is currently behind the Rockies' other relievers as a result of the delay, but he's expected to be included on the 30-man roster when Colorado opens its season Friday in Texas.

Rockies' Jairo Diaz: Yet to report
by RotoWire Staff | RotoWire

Diaz is yet to join his teammates at camp as he waits to finish clearing MLB's coronavirus protocols, Nick Groke of The Athletic reports.

There's been no indication that Diaz has tested positive for the virus himself, so his delayed arrival isn't necessarily cause for significant concern. He won't have much time to build up to game shape once he eventually arrives, but he's eventually expected to fill a high-leverage role for the Rockies.

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.

September 22, 2019 12:44 AM
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.

September 14, 2019 07:40 AM
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.
