The Texas Rangers have signed reliever Aaron Heilman to a minor league deal, reports Anthony Andro of Fox Sports SouthWest.
The 33-year-old right-hander had signed a minor league contract with the Mariners in January but was released on Sunday after throwing just four innings this spring.
He appeared in 32 games for the Diamondbacks last season, amassing an unsightly 6.88 ERA and 1.670 WHIP in 35 1/3 innings.
Heilman had a solid three-year stint from 2005-2007 as a reliever for the New York Mets, putting up a 3.27 ERA, 7.8 K/9 and 1.128 WHIP in an average of 94 innings, but has struggled in the four seasons since then.
For his career, which now spans nine seasons, Heilman has a 4.40 ERA, 3.7 BB/9, 7.8 K/9 and a 1.362 WHIP.
He has been assigned to the Rangers' Triple-A affiliate in Round Rock, Texas.
