The West Coast seems to bring out the best in Giancarlo Stanton.

On Thursday, with family members on hand after making the drive down from his hometown outside Los Angeles, Stanton blasted a two-run home run in the 11th as the Marlins opened an 11-game road trip with a 3-1 victory over the San Diego Padres.

“It’s the Cali air,” Stanton said afterward with a smile. “I grew up breathing it.”

Stanton’s home run came on an 0-2 pitch from Padres reliever Dale Thayer just after second baseman Jedd Gyorko muffed an easy ground ball for an error to keep the inning going.

But it was not just any home run. It was hit on a line to right-center in a park where that seldom happens.

“That’s probably the best pitch (Thayer) threw,” said Padres catcher Yasmani Grandal. “He painted it. It was right on the spot. But there’s only one guy that can hit that, and he was at the plate. I guarantee you there’s not another player in this league who could hit that pitch.”

Stanton said Thayer made him “look silly” on the previous pitch, a high fastball that he swung at and missed. So he knew the pitcher would either waste one in the dirt, or come back with another high heater.

“That was just putting the barrel on it,” Stanton said. “It wasn’t a home run swing. But when you have an easy swing like that, good things happen.”

Stanton didn’t even think the ball was going out after it left his bat. But he thought it would perhaps hit the fence and enable Dietrich to score from first. The ball went out, though, continuing Stanton’s run of success out West.
