Pete Alonso slugs two home runs as Mets pummel Rockies to win series

DENVER — The Mets haven’t seen this version of Pete Alonso nearly enough this season but were reminded Thursday about their slugging first baseman’s potential to take over a game.

It’s Coors Field, so the ball was flying, but Alonso hit two shots with such authority that the setting was merely incidental.

With his bat providing the thunder, the Mets were afforded an easy afternoon before catching another flight after a 9-1 victory over the Rockies.

Alonso homered in the first and third innings, and Mark Vientos contributed a blast in the fifth to provide David Peterson, who grew up in nearby Aurora, Colo., plenty of support in his homecoming game.

The Mets (61-54) won their second straight and for the third time in four games to complete a series victory in the third leg of this four-city trip.

Along the way, they moved a half-game ahead of the Braves in the race for the NL’s third wild card.

On the road trip the Mets are 4-3, with a three-game weekend series in Seattle still awaiting. The Mets have bounced from Anaheim to St. Louis to Colorado over the last week.

Alonso, in his final months before free agency, hasn’t produced with a high level of consistency this season — most glaring is his .694 OPS with runners in scoring position — but still has a chance at reaching 40 homers for a third straight season.

Alonso’s two homers Thursday gave him 25 this season.

Alonso was asked if there’s still a surge in him that will allow him to reach 40 homers.

“For sure,” Alonso said. “I just think through the course of the season there are ebbs and flows, and ultimately, I just want to help the team win. I just want to be the best I can and help get this team to the playoffs.”

The Mets attacked quickly against lefty Austin Gomber.

Francisco Lindor, whose two-run single a night earlier put the Mets ahead for good in the ninth inning, led off the game with a double.

Jose Iglesias and J.D. Martinez each doubled to give the Mets a 2-0 lead before Alonso launched a 471-foot rocket to left-center for the second-longest homer of his career.

Alonso homered again leading off the third, giving him the 21st multi-homer game of his career and second this season. The other this year occurred April 13 against the Royals at Citi Field.

“We have been talking about how deep our lineup is and [Alonso] has been hot and cold at times,” manager Carlos Mendoza said. “But he can carry a team for quite a bit, and we saw it today. He hit two balls and he hit them pretty far, and that is who he is. I think a lot of people have seen it before and are hoping that he gets going here and can show us the type of hitter that he is.”

Alonso had to settle for a single and two strikeouts over his three remaining plate appearances for the afternoon. He was asked if he thought about a three-homer game.

“Honestly, I just want to keep having good at-bats and doing the best that I can, just stick to my plan and my approach,” Alonso said. “Homers can be happy accidents, just the result of swinging and capitalizing on a good pitch and hitting it hard to the big part of the field.”

Vientos’ two-run homer in the fifth buried the Rockies in a 7-0 hole. Alonso singled with two outs in the inning before Vientos cleared the left-field fence.

Peterson loaded the bases in the fifth but escaped with only one run scoring on Brenton Doyle’s sacrifice fly.

Peterson lasted five innings and allowed one earned run on four hits with five strikeouts and three walks. Adam Ottavino, Ryne Stanek and Danny Young combined to pitch the final four innings behind Peterson.

The Mets extended their lead to 9-1 in the eighth on Lindor’s RBI single and Iglesias’ sacrifice fly.

Tyrone Taylor doubled in the inning after Harrison Bader was hit by a pitch.

“We had good at-bats from the first pitch of the game,” Mendoza said.
