Edmundo Sosa hit a tiebreaking single in the ninth inning, Tyler O'Neill made a running catch for the final out and the St. Louis Cardinals defeated the Los Angeles Dodgers 3-2 Tuesday night.

It was a rewarding victory for the Cardinals, who found out before the game that Jack Flaherty, their ace right-hander, will be sidelined for a while due to what manager Mike Shildt termed a ''significant'' oblique injury.

O'Neill led off the ninth with a single against Blake Treinen (1-2) and stole second base. He scored when Sosa hit a sharp grounder into left field. Dodgers third baseman Justin Turner was playing in near the infield grass and was unable to get a glove on the ball.

The Dodgers had a chance in the ninth after pinch-hitter Yoshi Tsutsugo drew a two-out walk and advanced to second on Cody Bellinger's single. Mookie Betts then lined a ball to the warning track in left, but O'Neill made a leaping grab to give Alex Reyes his 16th save.

John Gant threw six shutout innings, but the right-hander did not factor in the decision after Matt Beaty's two-run homer in the seventh off Giovanny Gallegos (3-1) tied it.

Tommy Edman and Dylan Carlson each had two hits and made great defensive plays in the sixth.

Edman made a leaping catch at second base to snag Max Muncy's line drive that had a hit probability of 91% according to MLB Statcast.

With runners on second and third, Carlson prevented Gavin Lux from tying the game when he made a sliding catch in center to end the inning.

St. Louis began the game with three straight hits off starter David Price. Edman led off with a double, advanced to third on a single by Carlson and scored when Paul Goldschmidt lined a ball into the corner in left field for a ground-rule double.

The Cardinals tacked on another run in the second when Carlson ended Price's night with a two-out single to drive in Jose Rondon.

The Dodgers finally broke through in the seventh to tie it. Albert Pujols drew a one-out walk before being lifted for a pinch-runner. Beaty then drove Gallegos' slider over the wall in right for his second home run of the homestand.

Gant allowed four hits with three walks and four strikeouts. It was only the second no-decision for the right-hander in his last nine starts.

arlos Martinez (3-4, 4.22 ERA) carried a no-hitter into the seventh inning in his last start on May 27 at Arizona before Ketel Marte broke it up with a single. Dodgers RHP Walker Buehler (3-0, 2.66) is 2-0 with a 2.00 ERA in his past four starts.
