VIDEO: D-Backs' Pollock robs Parker of HR

San Francisco Giants right fielder Jarrett Parker thought he hit a home run Friday night.

Arizona Diamondbacks center fielder A.J. Pollock said, "I don't think so."

Pollock went up to bring the baseball Parker hit, destined to leave AT&T Park, back into the yard.

Yeah, that was nice. And Pollock's done it all year. He came into the game credited with 12 Defensive Runs Saved, according to FanGraphs.

Let's go ahead and make it 13.
