PHOENIX (AP) — Cliff Pennington’s sacrifice fly to deep left field drove in the winning run in the bottom of the 10th inning as the Arizona Diamondbacks beat the Colorado Rockies 4-3 on Friday night.

Welington Castillo led off the 10th against Yohan Flande (0-1) with a double off the fence in right field. Castillo moved to third on Chris Owings’ single and scored easily on Pennington’s fly ball.

Pennington had the game-tying hit in the sixth inning and earned the third walkoff win for Arizona this season. Andrew Chafin (5-0) got the win in relief after pitching a scoreless 10th.

The Rockies lost a chance to take the lead in the top of the 10th after getting the first two batters on base. Pinch-hitter Michael McKenry lined out to shortstop Nick Ahmed, who doubled off Wilin Rosario at second. Then Chafin struck out Drew Stubbs to end the inning.
