Yadier Molina got the loudest boos during pregame introductions. The five-time All-Star catcher got booed again as he rounded the bases for his game-turning homer.
On opening day, he was driving them batty in Cincinnati again.
Molina broke a seventh-inning tie with a home run and made a pair of slick defensive plays on Monday, leading the defending National League champion St. Louis Cardinals to a 1-0 victory over the Reds.
Everyone knew the star of this one.
"Matt Holliday said it best when we were coming in shaking hands: 'Yadi wins,'" starter Adam Wainwright said.
It wasn't all Molina. The Cardinals' impeccable pitching was in top form, too.
The Reds were blanked on opening day for the first time since 1953, ending the second-longest streak of scoring in at least one run in season openers in major league history. The Phillies went 62 years without being blanked in an opener from 1911-72.
Wainwright used his refined sinker to finally get the best of the Reds, who have hit him like no other team. Wainwright allowed three hits in seven innings, fanning nine.
"I've never pitched great against the Reds," said Wainwright, who threw 105 pitches. "Today I wanted to make the emphasis on executing pitches. I tried to simplify it as much as possible."
Brewers 2, Braves 0: Brewers star Ryan Braun drew a standing ovation in his return from a drug suspension, then was ruled out in the first call overturned under baseball's expanded replay system as Milwaukee beat visiting Atlanta.
Braun went 1 for 4 and stole a base in the fourth inning that helped set up a two-run double by Aramis Ramirez.
A smattering of boos during Braun's first at-bat was easily drowned out by the overwhelming applause. The former MVP was suspended for the final 65 games last year in the Biogenesis doping scandal.
Later, Braun had his infield single to lead off the sixth overturned to out after the call was challenged by Braves manager Fredi Gonzalez under Major League Baseball's new replay format.
The review took 58 seconds.
Yovani Gallardo (1-0) tossed six shutout innings for the win.
Making his first opening day start, Julio Teheran (0-1) allowed two runs and seven hits in six innings.
