ST. LOUIS — Michael Wacha wasted no energy pondering the weather. The Cardinals pitcher concentrated on shutting down the opposition, waiting for the big swing that decided the outcome.
"I felt good going out there and felt good going back out there after the rain delay," the 22-year-old right-hander said after a 2-0 victory over the Giants on Saturday. "It's pretty crazy how much it rains, actually. I'm pretty used to it."
The experience was brand new for rookie Oscar Taveras, who made the Giants pay for a hanging curveball then made a curtain call during his major-league debut.
"What a great day for him, one I'm sure he'll never forget, and neither will we," manager Mike Matheny said. "For him to come up and do it in that situation, it's kind of mind-boggling."
Wacha pitched six three-hit innings in his fifth rain-delayed start this season, and Taveras homered in his second career at-bat.
"Everybody knows it's gone," Taveras said. "That was a good swing right there. I'm so happy right now."
Yusmeiro Petit gave up two hits in six innings for San Francisco, but one 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.
"Our guy did a good job," Giants manager Bruce Bochy said. "We just didn't do anything offensively."
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 in his last start for a storm that failed to materialize, and the Cardinals lost in 12 innings.
Wacha's debut a year ago against the Royals was delayed more than 41/2 hours after the bullpen gave up the lead and finished at 3:14 a.m.
"This guy's going to be tough as nails, if he's not already," Matheny said of last fall's NLCS MVP. "You can't put a young pitcher through much more than what he's been put through."
St. Louis ended a three-game losing streak.
