UPDATE: Jayson Stark of ESPN.com reports that Wolf has immediately signed with the Marlins and will presumably step into Jose Fernandez’s vacant rotation spot.
For the second time this season veteran left-hander Randy Wolf has opted out of a minor-league contract, asking for his release from the Diamondbacks after signing with Arizona a month ago.
Wolf previously asked to be released by the Mariners at the end of spring training despite securing a spot in their Opening Day rotation because he balked at agreeing to a 45-day release waiver request. And now the 37-year-old is a free agent again while trying to make a successful comeback from Tommy John surgery that knocked him out for all of 2013.
Wolf started six games at Triple-A for the Diamondbacks and struck out 35 batters in 34 innings, but he also walked 18 and posted a 4.50 ERA. His best shot to get back to the majors might be shifting to the bullpen.
