SAN FRANCISCO (AP) — Patrick Bailey hit a walk-off three-run homer, Kyle Harrison pitched six shutout innings and the San Francisco Giants beat the Pittsburgh Pirates 3-0 on Friday.

The game was scoreless until the ninth, when Michael Conforto walked and Matt Chapman singled to begin the inning off reliever David Bednar (1-2). Bailey then drilled a homer to right field, his second-career walk-off home run. The Giants catcher, off to a hot start this season, said he was looking for a fastball on the pitch and feels as if his swing is in a much better spot compared to this time last year.

“One thing this year I tried to build was just my confidence at the plate,” Bailey said. “I felt like I proved to myself last year that I could do it at this level, even with the struggles at the end. So that was my biggest thing this year was just going up confident every time — no matter what.”
