Pete Alonso coming up big for Mets in more ways than one

The spring of Pete Alonso continued Tuesday night, as the sizzling first baseman added another key run-scoring double in a 5-1 win over the Phillies at Citi Field.

And he added some excellent work with his glove — particularly in the top of the second, when Alonso picked a tough throw from Mark Vientos to prevent a run from scoring.

Afterward, Carlos Mendoza called Alonso “probably the best in the game” at scooping balls in the dirt at first base.

“For me, I want to be the best first baseman I can be,” Alonso said. “That’s part of my game and the position and I take immense pride in all of it.”

But Alonso’s calling card will always be his bat, and on Tuesday he came to the plate with two outs in the bottom of the seventh of a one-run game and the equally red-hot Francisco Lindor at third.

Alonso ripped a double to left to score Lindor, his 25th RBI of the young season — tied with Aaron Judge for most in the majors — as the Mets showed no signs of slowing down with a sixth straight win.
