PHOENIX — Randy Wolf’s career as a Diamondback is over before it ever truly began.
The Diamondbacks on Wednesday granted the veteran left-hander his release after Wolf exercised the out clause in his minor league contract.
Shortly after the D-backs announced his release, Wolf signed with the Miami Marlins to bolster a pitching staff dealing with the season-ending loss of ace Jose Fernandez.
Wolf signed a minor-league deal with the Diamondbacks on April 11. He was assigned to Triple-A Reno, where he went 5-1 with a 4.50 ERA in 34 innings over six starts. He struck out 35 batters.
Wolf came to spring training with the Seattle Mariners after a year out of baseball while recovering from Tommy John surgery. He pitched well enough to earn a rotation spot but was released after refusing the Mariners’ request to sign a 45-day advance-consent clause, which would have allowed the team to released him within 45 days of opening day without obligation to pay his salary.
Wolf seemed likely to have an opportunity with the D-backs when the team’s rotation struggled early in the season. Instead, the D-backs moved reliever Josh Collmenter to the rotation and gave opportunities to rookies Mike Bolsinger and Chase Anderson.
