Tyler O'Neill doubled home the tiebreaking run in the eighth inning and the slumping St. Louis Cardinals beat the Miami Marlins 4-2 on Monday night to halt a three-game slide.

Adam Wainwright tossed six effective innings and Paul Goldschmidt had two hits and an RBI as the Cardinals won for only the third time in 14 games.

Dylan Floro (2-4), the fifth Miami pitcher, began the eighth with a walk to Dylan Carlson before Goldschmidt singled. With one out, O'Neill hit his second double of the game to score Carlson, who had two singles.

Paul DeJong drove in Goldschmidt with a groundout to make it 4-2.

Giovanny Gallegos (4-1) pitched a hitless inning and Alex Reyes retired the side in the ninth for his 17th save.

Miami had won four of five.

The Cardinals tied it 2-all on an RBI single by Goldschmidt in the fifth when St. Louis knocked out 23-year-old rookie starter Braxton Garrett, who went 4 1/3 innings.

Jazz Chisholm Jr. singled with two outs in the third, scoring Jon Berti and Starling Marte, to give Miami a 2-1 lead. Wainwright loaded the bases on a single and two walks after retiring the first two batters.

Chisholm has reached base in 20 of the 22 games he's played since returning from the injured list May 16.

St. Louis scored its first run in the second on a single by Edmundo Sosa.

The 39-year-old Wainwright faced an opposing pitcher with fewer then 10 career appearances for the fourth straight start. He allowed two runs and four hits with six strikeouts, fanning Jorge Alfaro in the fourth for his 1,900th career punchout.
