ST. LOUIS (AP) – Michael Wacha worked six innings of three-hit ball in his fifth rain-delayed start of the season and Oscar Taveras homered in his second career at-bat for the St. Louis Cardinals in a 2-0 victory over the San Francisco Giants on Saturday.

Yusmeiro Petit (3-3) gave up two hits in six innings for the Giants, but one of them was Taveras’ 418-foot drive in the fifth. Petit subbed for injured Matt Cain, placed on the 15-day disabled list with a hamstring injury, for the second straight start.

The Cardinals have piled up 6 hours, 30 minutes of idle time in Wacha’s starts, with delays of 51 and 47 minutes Saturday. The total includes a 61-minute weather delay before the first pitch against the Yankees his last start for a storm that failed to materialize, and the Cardinals lost in 12 innings.
