The Diamondbacks have signed left-hander Randy Wolf to a minor league contract, reports Jon Heyman of CBSSports.com. He will earn $1 million while in the big leagues.
Wolf, 37, won a rotation spot with the Mariners in spring training, but he opted out of his contract when the team tried to renegotiate the terms. Wolf missed all of 2013 following Tommy John surgery. He went 5-10 with a 5.65 ERA with the Brewers and Orioles in 2012, his last healthy season.
Arizona's starters have a 6.57 ERA so far this year, the worst in the NL by more than a full run. As a result, manager Kirk Gibson said the team is considering making changes to the rotation. Here is his quote, courtesy of MLB.com's Steve Gilbert:
"We've had discussions," Gibson said. "Obviously things have not been going as we planned. We're better than this and we can't keep going on in this fashion. Nothing is concrete at this time. We'll continue to talk about it. We'll get through this road trip and we'll probably talk about it on a daily basis. Obviously we want to try to make it better. We need to get more innings out of our starters, No. 1."
Long reliever Josh Collmenter (2.25 ERA) is a candidate to move into the rotation. He worked four innings on Wednesday as the team tries to stretch him out. Wolf would also be a candidate, obviously. Top prospect Archie Bradley does not appear to be an option at this point.
Randall Delgado (10.13 ERA) and Trevor Cahill (7.90 ERA) appear to be most at risk of losing their rotation spots, according to Gilbert. Brandon McCarthy (7.82 ERA) hasn't been much better overall, but he has a big money contract. Same with Bronson Arroyo (4.82 ERA). Lefty Wade Miley (4.05 ERA) has pitched well. The team lost ace Patrick Corbin to Tommy John surgery in spring training.
The D-Backs made a run at Masahiro Tanaka over the winter before he signed with the Yankees. They eventually settled on Arroyo. Another free agent veteran like Freddy Garcia could be a rotation option as well.
Arizona has had a poor start to the season, losing eight of their first 12 games.
