After being nasty weathered out last night, the Stros wasted another strong pitching performance from Roy O and lost to the Pittsburgh Pirates on Wednesday night, 4-2. The loss was the Astros’ fifth in their last seven games. Andy Pettitte comes off the disabled list on Thursday afternoon to pitch the final game of the series in Pittsburgh before the Stros come back to Minute Maid Park on Friday night behind the Rocket to begin a four game set with the Cincinnati Reds. Ricky Stone was sent down to AAA New Orleans to make room for Pettitte on the 25 man roster.
