Right-handed reliever Hansel Robles has been promoted to the Mets to fortify the team’s bullpen after Jerry Blevins’ forearm fracture.
The 24-year-old Robles was off to a terrific start for Triple-A Las Vegas. In 7 2/3 innings over five outings, he had not allowed a run, while striking out 10 batters and walking one of the 30 opposing hitters he had faced. Two of the six hits he had allowed were doubles, but he had not allowed a hit to lefties in nine at-bats.
The Mets moved Robles out of the Double-A starting rotation in 2014 and into the bullpen at midseason, and his results have been excellent ever since.
As a starter, he ran a fairly pedestrian 4.86 ERA in Double-A with a 9 percent walk rate and 21 percent strikeout rate. However, as a reliever between Double-A and Triple-A he owns a 1.30 ERA in 27 2/3 innings with 34 strikeouts against eight walks, good enough for a strikeout rate of 30.6 percent and a walk rate of 7 percent. As a starter, in Double-A, his fastball was below average — often in the 89-91 range, although he would reach back for more at 93. However, his velocity has jumped in of the bullpen and multiple reports had him working off a 93-96 mph fastball.
