ST. LOUIS (AP) — 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 afternoon.

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 Velazquez.

David Robertson (2-0) retired three straight batters in the bottom half, and the Cubs took two of three from their rival. Chicago has won four of its last five series in St. Louis.

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.

Nick Wittgren allowed four straight singles starting the fourth, including Alex Rivas’ RBI hit. Johan Oviedo gave up a one-out double to Rafael Ortega, and Contreras followed with the tying hit.

Nolan Arenado had a run-scoring single in the first, Tommy Edman grounded into a run-scoring forceout in the second and Brendan Donovan, Paul Goldschmidt and Juan Yepez homered in a 12-pitch span in the third off Alec Mills. Donovan and Goldschmidt hit back-to-back drives, with Goldschmidt’s his team-leading 18th.

UP NEXT: Cubs RHP Keegan Thompson (7-2, 3.10 will face Cincinnati RHP Luis Castillo (2-4, 3.71) on Tuesday in the first of a three-game set in Chicago. Thompson has allowed just one run over his last 12 innings.
