Willson Contreras hit a tiebreaking single in the 10th inning to drive in his third run of the game, and the Chicago Cubs overcame a five-run deficit to be the St. Louis Cardinals 6-5 on Sunday.
St. Louis led 5-0 but starter Jack Flaherty left after two innings because of right shoulder tightness, and the Cubs tied the score with a five-run fourth. The Cardinals have lost three of their last four games and seven of their last 10.
Contreras hit a tying two-run single in the fourth and led off the 10th with a single off Zack Thompson (1-1) that scored automatic runner Nelson Velázquez.
David Robertson (2-0) retired three straight batters in the bottom half.
Flaherty was making his third start this season after missing the first 64 games while recovering from shoulder surgery. He gave up one hit, struck out two and walked two, throwing 49 pitches.
