Pete Alonso took center stage Monday night, putting his record-shattering power on display by winning the Home Run Derby. In between his bat-flips and long-balls, many paid homage to his nickname: the “Polar Bear.”

Funny enough, the Mets star earned the label from a fellow Home Run Derby champion.

“Todd Frazier. In Spring Training, he said ‘You look like a big, damn polar bear.’ And then it just kind of stuck,” Alonso told reporters Monday night in Cleveland. “So if any of you guys know Todd Frazier, he’s a loud mouth from Jersey. He tells it how it is. But I love that guy. He’s a great teammate. But he’s quite the character. He’s a clown. But definitely got it from him.”

Noah Syndergaard was the first to bring the arctic moniker to the public, dubbing him “Pete the Polar Bear” after the Mets’ opening series win against the Nationals.

The nickname has followed the rookie phenom for most of the season, thanks to his raw strength and body shape that has led to 30 home runs (already Mets rookie record) and 68 RBIs in 89 games.

Before the Mets played the Braves in late June, Jeff McNeil and Dominic Smith brought a giant stuffed polar bear into the dugout to meet with the media, naming him Pete.

When asked about his new alias, Alonso at the time said “I’ll embrace it.”
