That Collin Cowgill hit a walk-off home run with two outs in the 14th inning to lift the Angels to a thrilling 2-1 victory over the Oakland Athletics on Tuesday night wasn’t all that surprising.

Despite his smallish 5-foot-9, 185-pound frame and limited big league resume, the 28-year-old reserve outfielder has shown some legitimate pop this season, with five homers in 142 at-bats.

What was truly stunning about Cowgill’s low liner into the left-field bullpen off Jeff Francis was that he somehow found a way to get a ball past Athletics left fielder Yoenis Cespedes, whose near superhuman defensive exploits are giving him a Paul Bunyan-like stature in the game.

“That was the only way we were going to score if we hit it to left field,” Cowgill said after the Angels extended their win streak to five and cut Oakland’s American League West lead to 2 1/2 games.

“Honestly, I was just hoping I got enough of it to get it over his head. He’s made some impressive plays against us. There’s no telling what that guy’s going to do in left field.”

That was never more true than in the eighth inning Tuesday night, when Cespedes, who threw out two Angels at the plate in the second inning of a May 31 game in Oakland, unleashed a throw that will be compared to some of the all-time great outfield plays.
