Looks like there are going to be some spots open at OKC, now that the Orioles have signed Ross Wolf to a minor-league deal.
Wolf appeared in 56 games for OKC in 2011, with a 4.76 ERA and 1.49 WHIP. Wolf came to the Astros' system from Baltimore in 2010, after he was traded to the Orioles by the A's for Jake Fox.
