A few minutes ago on Twitter Mike Vassallo posted the following:
Wolf had posted a 5.69 ERA as a Brewer this season and led all major leaguers with 179 hits allowed. His 90 earned runs allowed were also the NL's highest total.
Wolf was in the final year of a three-year contract with the Brewers, who will still owe him roughly $2.9 million for the remainder of this season plus the $1.5 million buyout of his contract for 2013. They could recoup a little of that money if another team signs him before the end of this season, but not much.
It's worth noting that Wolf had actually been relatively good in his first two seasons as a Brewer, posting a 3.93 ERA and throwing over 420 innings. This year, however, the results just weren't there. Wolf's turn in the rotation was scheduled to come up this weekend but now will likely be filled by Shaun Marcum.
Jeff Bianchi, meanwhile, rejoins the Brewers after a 4-for-4 night in Nashville last night.
