That's how you turn a mild downer into an exciting trade. Unable to acquire Jonathan Singleton from the Phillies, the Astros instead flipped Anthony Gose to the Blue Jays for first base prospect Brett Wallace. That means this deal plays out in full as Roy Oswalt plus $11M for LHP J.A. Happ, 1B Brett Wallace, and SS Jonathan Villar.
Brett Wallace is one of the top first base prospects in the minor leagues, and he is major league ready right now. He has enough lefthanded power for the position, projecting to hit around 20-30 homers per year, and he should hit for average as well, enough to get on base at a respectable rate. Although he used to play third base, questionable defense forced him to first, where he should be fine. While he has a good approach at the plate, he hasn't drawn many walks in the minor leagues. His approach should be similar to Chris Johnson's, and he should have the bat to carry first base next year and down the road.
