Jeff Karstens was pitching for his major league job and Jason Jaramillo had three hits to lead the Pirates over the St. Louis Cardinals 2-0 on Saturday night.

Karstens (1-1) combined with four relievers on a four-hitter. Jaramillo, the Pirates’ backup catcher, tied a career high with his third three-hit game and had an RBI single.

The Pirates won for the fourth time in their last five games and beat St. Louis for just the fourth time in the last 14 meetings. The Cardinals lost their fourth in five games
