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.

Rockies' Jairo Diaz: DFA'd Sunday
by RotoWire Staff | RotoWire

Diaz (forearm) was designated for assignment Sunday, Thomas Harding of reports.

Diaz, who is on the 7-day disabled list with forearm tightness, has been cast off the 40-man roster in order to make room for the contract selection of reliever Jerry Vasto, who joined the Rockies' bullpen Sunday. Diaz owns a 9.82 ERA over 3.2 innings of relief with Triple-A Albuquerque this season.

Rockies' Jairo Diaz: Optioned to minors
by RotoWire Staff | RotoWire

Diaz was optioned to Triple-A Albuquerque on Sunday, Thomas Harding of reports.

Diaz was in competition for a back-end bullpen role this spring, but the Rockies have decided to option the 26-year-old to Triple-A after he posted a 3.72 ERA over 9.2 innings of spring ball. Diaz has just 29.2 innings of major-league work under his belt during his eight-year professional career.

February 27, 2018 01:48 PM
Rockies' Jairo Diaz: Tosses two scoreless innings to start spring
by RotoWire Staff | RotoWire

Diaz (elbow) has two scoreless innings under his belt this spring.

Diaz appeared in just four games with the Rockies last season and missed a chunk of time with elbow inflammation. He's in line to compete for a back-end bullpen role, but he'll need to stay healthy and perform well throughout spring training if he wants to overcome competitors like Carlos Estevez (oblique) and Scott Oberg.

Rockies' Jairo Diaz: Comes off disabled list
by RotoWire Staff | RotoWire

Diaz (elbow) was reinstated from the 60-day DL on Friday.

Diaz was placed on the shelf in early September with inflammation in his pitching elbow and only wound up playing in four games with the Rockies this past season. Barring any setbacks, he should be ready for action come spring training.

Rockies' Jairo Diaz: Hits disabled list
by RotoWire Staff | RotoWire

Diaz was recalled from Triple-A Albuquerque on Sunday and placed on the 60-day disabled list with elbow inflammation.

Diaz last pitched in mid-August but has seemingly been bothered by an elbow injury since. He threw five innings over four games in the majors this season. Diaz struggled in that time, as he allowed five runs on 12 hits and five walks.

July 25, 2017 04:40 PM
Rockies' Jairo Diaz: Optioned to Triple-A
by RotoWire Staff | RotoWire

Diaz was optioned to Triple-A Albuquerque on Tuesday, Patrick Saunders of The Denver Post reports.

He has electric stuff when he's on, but in five big-league innings this season he has given up five runs on six hits and five walks, so more seasoning is likely needed against Triple-A hitters. Carlos Estevez was promoted as a corresponding move.

July 17, 2017 07:20 PM
Rockies' Jairo Diaz: Returns to big leagues
by RotoWire Staff | RotoWire

Diaz was recalled from Triple-A Albuquerque on Monday, Thomas Harding of reports.

Diaz struggled in his first cup of coffee in the big leagues, but he's dominated Triple-A hitters to the tune of a 2.13 ERA and an 11.8 K/9. He'll look to carry that success into the Rockies' bullpen as he replaces Zac Rosscup, who was optioned to Triple-A in a corresponding move.

June 28, 2017 02:04 PM
Rockies' Jairo Diaz: Sent back to minors
by RotoWire Staff | RotoWire

Diaz was optioned to Triple-A Albuquerque on Tuesday.

Diaz made just one appearance before being sent back to the minors; he allowed three runs (two earned) on four hits in just one inning of work. The 25-year-old will head back to Triple-A until the Rockies find themselves in need of a fresh arm in the bullpen.

June 27, 2017 02:20 PM
Rockies' Jairo Diaz: Promoted to majors
by RotoWire Staff | RotoWire

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

The righty started the season on the disabled list after undergoing Tommy John surgery in March of 2016, and he compiled a 3.52 ERA and nine strikeouts in 7.2 innings for Albuquerque before being promoted. He'll likely start out in low-leverage roles, but the 25-year-old could work his way up into higher-leverage innings if he pitches well.

Rockies' Jairo Diaz: Makes rehab appearance at High-A
by RotoWire Staff | RotoWire

Diaz (elbow) tossed a scoreless inning during a rehab appearance Monday with High-A Lancaster, conceding one hit and striking out one batter.

It was Diaz's first appearance in a game in more than a year following Tommy John surgery in March of 2016. The right-hander will likely require several more rehab outings at multiple minor-league affiliates before the Rockies activate him from the 10-day disabled list, perhaps at some point in May. He'd likely be ticketed for low-leverage work initially upon rejoining the big club, but could move up in the bullpen pecking order if he performs well.
