Adam Wainwright credits a more rigorous pregame warmup routine as part of the reason for his May rebound. Wainwright hit a two-run homer off Brandon McCarthy and pitched six innings of four-hit ball, leading the St. Louis Cardinals over the Los Angeles Dodgers 2-0 on Thursday for a four-game split. ''Earlier in my career it was a little different when I took the mound, my first pitch of the game I was hot and I was ready to rock,'' the 35-year-old Wainwright said.
