ST. LOUIS (AP) The St. Louis Cardinals used power to tie the game, and took advantage of a mistake by the Chicago Cubs to win it.
Greg Garcia hit first career home run - a pinch-hit blast in the eighth inning - and Peter Bourjos scored the winning run from third on a bases-loaded, no-out, throwing error by Mike Baxter to help the Cardinals to a 3-2, 10-inning win in a battle of NL Central rivals.
It was St. Louis' fourth win in a row and seventh straight at home, and the Cardinals improved to a major-league best 27-7 at home.
With the game tied in the 10th, Jhonny Peralta slapped a routine grounder to second base, where Baxter - the right fielder - had come in to play with the bases loaded, giving the Cubs five infielders. Baxter cleanly fielded the ball and had plenty of time, but threw wildly to the third-base side of the plate.
''I threw it away, I didn't make the play,'' Baxter said. ''It's something I'm very capable of doing.''
Bourjos began the 10th inning with a double off reliever Justin Grimm (1-2). Kolten Wong followed with a single off the second base bag and Matt Carpenter was walked to load the bases.
Seth Maness (2-0) picked up the win in relief.
Chicago lost its third in a row after a four-game winning streak.
Garcia set up the Cardinals' sixth extra-inning win in nine tries with his homer off Pedro Strop leading off the eighth that tied it at 2. It was the Cardinals' first pinch-hit homer of the season - from an unlikely source.
''I'm not a power hitter by any means,'' Garcia said.
Garcia is 3 for 4 as a pinch-hitter since being recalled from Triple-A Memphis on June 19.
''I had a feeling he was going to throw me a fastball,'' Garcia said. ''I put a good swing on it. It was surreal. I can't even put it into words.''
St. Louis manager Mike Matheny was confident that Garcia would at least get on base.
''I figured he'd go up there and put a pretty good rip into it,'' Matheny said. ''I didn't expect to see the ball leave (the park). What a great surprise. He's done a nice job whenever we do get him an opportunity.''
Kris Bryant gave Chicago a 2-1 lead by driving in Dexter Fowler with a sacrifice fly to center in the seventh off Cardinals starter John Lackey, who gave up two runs on eight hits in seven innings. Fowler started the inning with a double.
''It was a tough one, they put some good at-bats on me,'' Lackey said. ''A lot of deep counts and I had to throw a lot of pitches. But for the most part, I was able to do some good damage control.''
Chicago starter Jake Arrieta allowed just one run on three hits over seven innings.
''I got into a groove and was able to hold them off,'' Arrieta said. ''But they did what they do, they fought back. This was a tough one. We were right there.''
Randal Grichuk gave St. Louis a 1-0 lead with a run-scoring triple in the second.
Chicago, which had scored just three runs over its previous three games, tied the game in the fourth on a RBI single by Baxter, who had three hits and helped Arrieta with a leap into the stands to snare a flyball by Peralta leading off the sixth.
The Cardinals are 27-18 against the Cubs over the last two-plus seasons.
''This one stings,'' Chicago first baseman Anthony Rizzo said. ''You can't give away a lead there.''
Cubs: Bryant returned to the starting lineup after being taken out of Thursday's game against the Los Angeles Dodgers with flu-like symptoms after the second inning. Fowler also returned after missing three games with a sore ankle suffered running the bases on Monday.
UP NEXT: Chicago RHP Donn Roach will make his first start of the season against RHP Michael Wacha (9-3, 2.85). Roach is replacing Tsuyoshi Wada, who suffered shoulder tightness in his previous start Monday. Roach was 7-1 with a 2.29 ERA for the Triple-A Iowa Cubs. Wacha began the season 7-0.
