It looks like the Diamondbacks and Aaron Heilman might have erred in trying the veteran setup man as a starter this spring. The 32-year-old right-hander was placed on the DL for the first time in his career Friday due to a case of shoulder tendinitis.
Replacing him on the roster will be 25-year-old righty Josh Collmenter.
Heilman, who lost out to Armando Galarraga for the last spot in Arizona’s rotation, had allowed nine runs in 6 2/3 innings out of the pen this season. Six of those runs came Wednesday in Arizona’s 15-5 loss to the Cardinals, when he was struggling to touch 90 with his usual 91-94 mph fastball.
Heilman is one of just four relievers to make at least 60 appearances and pitch at least 60 innings each of the last five years, joining Jonathan Broxton, Francisco Cordero and Mariano Rivera. And that’s actually setting the bar low for him: he was over 70 appearances and 70 innings in each of the five seasons, something none of those closers did. Only two other pitchers (Matt Guerrier and Jon Rauch) matched those marks over four of the last five seasons.
