Pete Alonso of the Mets wins All-Star Home Run Derby

Cleveland – Pete Alonso took one final swing and flipped his bat high in the air. Another walkoff.

As the crowd roared, the New York Mets rookie headed toward the mound and tightly squeezed his cousin and pitcher Derek Morgan, who had helped him win the All-Star Home Run Derby and $1 million.

Alonso outlasted a worn-down fellow rookie Vladimir Guerrero Jr. in the final round Monday night to take home a prize that nearly doubled his 2019 salary.

With just seconds to spare, Alonso connected for a homer to left-center to edge Guerrero 23-22 after the Blue Jays' powerhouse put on a historic display by hitting 91 homers before he ran out of gas following an epic semifinal matchup against Dodgers outfielder Joc Pederson.

"There's so many guys that just put on a show, like Joc, he was amazing, Vladdy, they did such a good job," Alonso said. "Everybody put on a show. To me it didn't really seem like the jitters were there, because everyone was awesome."

After his last homer cleared the wall, Alonso was swarmed by the NL All-Stars. "This was surreal," Alonso said.

Alonso is the second rookie to win outright, following Yankees star Aaron Judge in 2017. He's also the first Mets player to win the Derby since Darryl Strawberry shared the title with Wally Joyner in 1986.

And he'll also give 10% of his prize money to charity — 5% each to the Wounded Warrior Project and to the Tunnel to Towers Foundation.

"I've been living a fantasy," Alonso said. "And I just want to use my platform … just reach out to people and just make people aware of these causes.."

Alsono showed some dramatic flair with two nail-biting wins to reach the final against Guerrero. He nipped Cleveland's Carlos Santana 14-13 in the first round and Atlanta's Ronald Acuna Jr. 20-19 in the second to set up a showdown with the 20-year-old Guerrero, whose Hall of Fame father won the event in 2007.

Guerrero figured to be a force but there was no way of predicting he'd hit 91 homers — 74 more than his dad's entire total 12 years ago.

"I was kind of scared he was going to beat me because he was hitting second," Guerrero said through a translator. "It was back-and-forth and back-and forth. It was really tiring."

"I gave all I had. I'm proud I hit 91 home runs," he said.

Guerrero defeated Pederson in a semifinal that was tied 29-all after their four-minute round and then again following a 60-second session. Guerrero and Pederson then each homered once when given three swings, forcing another best-of-three round.

Guerrero hit two, screaming at his second shot, which barely cleared the 19-foot wall in left. Pederson couldn't match up, hitting a grounder on his final cut before both players shared an exhausted embrace near home plate as the fellow All-Stars stood and applauded like regular fans.

The last Home Run Derby in Cleveland was also won by a New Yorker — Yankees first baseman Tino Martinez, who took the 1997 crown over a field that included Hall of Famers Ken Griffey Jr. and Jim Thome, who didn't clear the walls once.
