The Cardinals scored early and often on Wednesday, exploding for a 15-2 win at Milwaukee. Scott Rolen led the way for St. Louis with two home runs, a double, three runs scored and four RBI. Mike Matheny drove in three runs for the Cardinals. Albert Pujols, Eli Marrero and Eduardo Perez had two RBI each. Pitcher Matt Morris even got in on the fun. He scored three runs and had two hits, including his first major league home run. Morris also picked up his first victory of the season, as he gave the Brewers just one unearned run in six innings of work. The Cardinals are off Thursday. They return home to host Arizona over the weekend.
