Astros pitcher Roy Oswalt will start his eighth straight opener for the club next month. Oswalt will extend his own franchise record. "I know it's kind of a foregone conclusion for everyone, but we're making it official," Houston manager Brad Mills said Saturday morning. "He's throwing the ball so well all spring long. "He's been healthy. He's gone about his business the way a No. 1 should and he's throwing the ball like a No. 1 should. Each time he goes out there it seems to be icing on the cake."
