Wallace, acquired by the Astros from the Blue Jays last week, was plugged into the starting lineup Saturday in his Major League debut as a replacement for Lance Berkman, who was traded to the New York Yankees after 11 years with the club.
Wallace, who was in the starting lineup Monday at St. Louis, is certainly familiar with Busch Stadium, having worked there when he signed his contract. He also played a few innings during last year's Futures Game.
"This is a great park and there's so much history, and all the fans here come out every night and support that team," Wallace said. "Getting to come back is pretty awesome. I thought I'd have a chance to play on the other side, but coming back here to the big leagues and playing against them is going to be a lot of fun."
Wallace has remained friends with several of the players currently on the Cardinals' roster, including Jon Jay, Tyler Greene and Nick Stavinoha.
"It's going to be fun to play against them and have a chance to see them," he said.
