PHOENIX (AP) -- The Diamondbacks have reinstated reliever Aaron Heilman from the disabled list and optioned struggling starter Barry Enright to Triple-A Reno.

The team announced the moves before Thursday night's game against Colorado.

Enright was 1-3 with a 6.49 ERA and 15 walks against 19 strikeouts in six starts. He gave up six runs and four walks in five innings of Wednesday night's 6-4 loss to Colorado.

Heilman went on the DL for the first time in his nine-year major league career on April 15 with right shoulder tendinitis. He missed 18 games.

Since 2006, the 32-year-old Heilman is the only relief pitcher to post five straight seasons of at least 70 relief appearances. He made the transition to the bullpen in May 2005.
