Still adjusting to the way breathing feels different, he returned Sept. 21, going 0-2 in three starts totaling 17 innings, so it wasn’t clear how he'd fare Wednesday.
Carpenter allowed seven hits and walked two across his 5 2-3 innings to improve to 10-2 over his career in the postseason. That includes a 4-0 mark while helping another group of wild-card Cardinals take the title in the 2011 World Series, when he won Game 7 against Texas.
The 10 victories tie Carpenter for seventh-most, behind Andy Pettitte’s record 19.
‘‘If the baseball world doesn’t know what an amazing competitor he is by now, they haven’t been paying any attention,’’ Cardinals left fielder Matt Holliday said.
Carpenter collected a pair of hits, including a double off the wall in the fifth that was about a foot or two away from being a homer. When he reached second base, he raised his right fist.
Earlier, Carpenter stepped to the plate for his first at-bat and chatted with umpire Joe West.
‘‘I say hello to him. And he said hello back, and he talked about what a beautiful day it was to play a baseball game. And I was like, ‘You ain’t kidding,'’’ Carpenter recounted. ‘‘Beautiful weather. The crowd is going crazy. ... There’s no question you take time to reflect on that.’’
NOTES: Holliday fouled a ball off his left leg in the eighth, stayed in to deliver a two-run single, then left for a pinch runner. ... Lohse beat the Braves in the wild-card game. ... Detwiler will be making the first postseason appearance of his career. His last regular-season start also came against the Cardinals, and he went only 2 1-3 innings, giving up seven runs. ... Wednesday was the 88th anniversary of Washington’s only World Series championship, won by the Senators on Oct. 10, 1924.
