Ross Stripling was in a celebratory mood and Michael Wacha was going to pay for it a second time after losing to his former college roommate. Stripling earned his first victory in his seventh major league start and got his first big-league hit in his initial at-bat off Wacha, Yasiel Puig homered and the Los Angeles Dodgers defeated the St. Louis Cardinals 8-4 Friday night in the series opener. Stripling squared off against Wacha, his former teammate at Texas A&M who - as the loser - was on the hook for a postgame dinner with their girlfriends.
