Jairo Diaz impressed in his first cup of coffee with the Rockies in 2015, raising hope that he could become a major cog in the bullpen very quickly. Those plans were quickly sidetracked, however, after he tore the UCL in his right elbow early in spring training, keeping him out for the entirety of the 2016 campaign. The right-hander's rehab seems to be going as scheduled, and considering the fact that his Tommy John surgery occurred so early in 2016, there's a decent chance he'll be ready to go by midseason. Diaz is only 25 years old, so if he can continue to throw in the upper-90s following the surgery and operate at the high level he displayed at the end of 2015, he could work his way into a prominent back-end role.
Diaz (elbow) pitched two-thirds of an inning in his first Cactus League appearance Monday, giving up five runs on five hits and a walk. The appearance is definitely a step in the right direction for the fireballer, and although the results are somewhat cringe-worthy, some positives can be taken away from the outing. Diaz's fastball touched 98.8 miles per hour, showing the high-octane delivery that has Rockies fans drooling. He also got the first two outs of the inning relatively quickly, one of them even being a strikeout. His rust became apparent afterward, however, as his inability to command his changeup and slider led to a home run and a premature exit from the contest. Diaz appears to be pretty healthy as of now, although he'll likely need some more work in game situations prior to being fully cleared for major league innings. His return to full-time work appears to still lie in early May.
Diaz (elbow) pitched an inning in a simulated game versus minor leaguers, Nick Groke of the Denver Post reports. The right-handed flamethrower continues to progress through his Tommy John rehab program at a good pace. Diaz will need to throw in regular game situations before he even sniffs the major leagues, but this development keeps him on pace for a potential return to the Rockies' bullpen sometime around early May.
Diaz (elbow) threw a bullpen session Friday, his first since undergoing Tommy John surgery this offseason, Nick Groke of The Denver Post reports. Diaz progressed steadily through rehab this winter, and bullpen coach Darren Holmes noted the young reliever "looks healthy." The 25-year-old started strong in the Rockies' bullpen last year, posting a 2.37 ERA over 21 games before being sidelined with an elbow injury. Diaz is on pace for a return closer to May, but this is a positive step on the road back.
Diaz (elbow) began a throwing regimen at the Rockies' facilities in the Dominican Republic over the offseason, Nolan Lees of Fansided reports. The flame-throwing 25-year-old was expected to settle into the Rockies bullpen full-time last season, but he was forced to undergo Tommy John surgery after tearing his UCL in early March. However, it seems like he's been progressing well through his rehab, and given the timing of his surgery, it's not completely out of the question for Diaz to return to the bullpen in the first month of the season. Not much further is known about his rehab progress beyond the limited throwing program, but things should become clearer as spring training approaches.
Diaz (elbow) has been placed on the 60-day disabled list by the Rockies. Considering Diaz will miss the entire 2016 campaign after tearing the UCL in his right elbow early in March, it shouldn't come as a surprise the club will open up a 40-man spot by placing him on the 60-day disabled list. Following an impressive stint with the Rockies after being recalled in August of last season (2.37 ERA, 1.16 WHIP), Diaz was expected to compete for a bullpen spot out of spring training. The 24-year-old Venezuelan will now shift his focuses to recovering for a run at the 2017 Rockies bullpen.
