ATLANTA – After Mike Minor pitched like a rising ace, he tipped his cap to the injured leader of the Atlanta Braves’ rotation.

Minor allowed only one run to give the depleted staff a lift, Jason Heyward homered, and the Braves beat Adam Wainwright and the St. Louis Cardinals 4-1 in a matchup of division leaders Friday night.

Minor (10-5) gave up four hits with no walks in seven innings. His sharp performance came two days after Tim Hudson was lost for the season with a broken right ankle.

Minor, who became the first Braves pitcher to reach 10 wins, lowered his ERA to 2.89. His strong start was especially important after Hudson’s season ended.

Asked if he felt he needed to step up as staff ace, Minor said, “That’s not really my role. I go out every fifth day and just try to pitch.

“With Huddy going down, that was our ace. That was our best guy. We just need everybody else to step it up a little bit.”

The Atlanta rotation also is without lefty Paul Maholm, who is expected to miss at least one start because of a bruised left wrist.

Braves Manager Fredi Gonzalez also resisted suggestions that Minor is emerging as the ace on a young staff that also includes rookies Julio Teheran and Alex Wood.

“Mike Minor doesn’t have to do anything,” Gonzalez said. “He’s been this good for a while. We saw him growing up and getting better and better about this time last year. Let’s let him dictate his own career.”

Wainwright (13-6), the NL leader in wins, took his first loss since a 2-1 decision to Texas on June 23.

Yadier Molina gave St. Louis a 1-0 lead with his eighth homer in the second inning. The Braves answered with two runs in the bottom of the inning.

Wainwright complimented the Braves’ hitters on their patience in trying for opposite-field hits.

“I think I just have to tip my hat,” Wainwright said. “I think they had a great approach from the first pitch of the game on.”
