HOUSTON, Tex. -- Bartolo Colon's 50-game performance-enhancing drug suspension concluded after Friday's game. He was on the mound in Houston on Saturday and it looked like he hadn't lost a step, especially early on. Colon's fastball topped out at 93 MPH as he held the Astros to three runs on eight hits and no walks over six innings. He threw 83 pitches and helped the A's win 6-3, their fourth victory in a row .
