SAN FRANCISCO | Ty Blach had a pretty good idea he had exceeded his teammates’ wildest expectations of what he could do with a bat. The reaction he got from teammate Denard Span rounding third base sealed it.

“Denard’s look in the on-deck circle, that was pretty funny, he was just kind of like ‘Did you just do that?’” Blach said. “That was a great moment.”

Blach pitched eight strong innings and hit a three-run homer and Jarrett Parker had three hits and three RBIs in his first game back from the disabled list as the San Francisco Giants defeated the Oakland Athletics 11-2 on Thursday night.

The win gave the Giants a split of the four-game home-and-home Bay Bridge Series.

Blach (7-7) struck out four and gave up two runs, six hits and one walk. The 26-year-old left-hander threw 104 pitches. He’s pitched at least six innings in six straight starts.

Blach homered off Chris Smith in the fifth. His first career home run cleared the 399-foot sign in center field and extended an 8-1 lead.

“It was the Ty Blach show tonight,” manager Bruce Bochy said. “What a game he had. I think we were all just stunned with what happened there.”

The Giants combined for 13 hits as they spoiled the return of Oakland A’s starter Kendall Graveman (2-3).
