FILE - In this May 21, 2012, file photo, Houston Astros' Bud Norris follows through with a pitch during a baseball game against the Chicago Cubs in Houston. After a 6-11 season in 2011, Norris approached Astros manager Brad Mills and said he wanted to be a different pitcher. Now he's proving he was serious about a turnaround. He's won each of his four starts in May and his 0.35 ERA this month is a major-league best for a starter. (AP Photo/Pat Sullivan, File)
