The Mariners have released Aaron Heilman from their minor league camp, according to Larry Stone of the Seattle Times (on Twitter).
Heilman, 33, signed a minor league deal with the Mariners this past January after posting a 6.88 ERA, 8.4 K/9, and 2.8 BB/9 in 35 1/3 innings for the Diamondbacks last season. He struggled to keep the ball on the ground, with a 38.5% groundball rate, which resulted in a whopping eight homers allowed.
The FrontLine Sports client has a career 4.40 ERA, 7.8 K/9, 3.7 BB/9, and 43.1% groundball rate in 630 innings as both a starter and reliever for the Mets, Cubs, and Diamondbacks.
