The Pirates announced that they designated right-hander Tim Wood for assignment to create space for Ross Ohlendorf on the 40-man roster. The Pirates recalled Ohlendorf from rehab, reinstated him from the 60-day DL and optioned him to Triple-A.
Wood, 28, has appeared in 13 games for the Pirates this year. He has spent most of the season with Pittsburgh's Triple-A affiliate, where he has a 2.84 ERA with 23 saves, 6.5 K/9 and 2.4 BB/9 in 44 1/3 innings. The former Marlin has a 4.50 ERA with 7.3 K/9 and 3.6 BB/9 in nine minor league seasons. It won't be surprising if he gets claimed within ten days.
