The Houston Astros have traded Luke Scott, Matt Albers, Troy Patton, Dennis Safarte, and Michael Constanzo in exchange for Miguel Tejada. Tejada is very reliable, and hit .296 last year with 18 HRs and 81 RBIs. Since the Astros have Ty Wigginton, I think they will keep Tejada at shortstop. Although this trade should improve their offense, they weakened their pitching so much that it still has them behind the Cubs and Brewers. Scott, Albers, and Patton should find spots in the Orioles lineup right away, and it gives them a chance to improve on their record from 2007.
