CHICAGO (AP) — After watching the Cubs waste a couple of leads, Kris Bryant felt a loss was almost inevitable.

That quickly changed with one swing by the Chicago slugger.

Bryant hit a go-ahead, two-run homer in the eighth inning to give the Cubs a 12-11 comeback victory over the San Francisco Giants in a wild, back-and-forth game Wednesday night at Wrigley Field.

“This is one of those games where you don’t feel like you’re going to win because you’re taking a lead and giving it back,” Bryant said. “But we came out on top, and definitely some good momentum here.”

Nicholas Castellanos and Kyle Schwarber also connected for Chicago, which has won four straight. The Cubs moved back into first place in the NL Central by a half-game over St. Louis, which lost to Milwaukee in a rain-shortened game.

Castellanos, who went 4 for 5, has homered in three consecutive games for the second time in his career — he also did it with Detroit in 2016 — and has eight in 19 games since being acquired in a trade before the July 31 deadline. He is batting .392 (31 for 79) with the Cubs.

Evan Longoria, Mike Yastrzemski, Stephen Vogt and Kevin Pillar homered for San Francisco, which has dropped three in a row.
