Pete Alonso’s frustration finally boiled over Monday night at Fenway Park, and unfortunately, so did another throw.

After a pair of misplays in back-to-back games, the New York Mets first baseman was caught on camera in the dugout slamming his glove against the wall multiple times, then launching his helmet in disgust. It was the second straight night Alonso found himself at the center of defensive lapses.

The latest error came in the fourth inning against the Boston Red Sox. With two runners on and a full count, Jarren Duran hit a routine ground ball to first base. Alonso fielded it cleanly but sailed the toss well over pitcher Kodai Senga’s head. Duran reached second, Carlos Narvaez moved up to third, and the Red Sox continued to control momentum in what was finally a 3–1 win.

The frustration wasn’t just about Monday, though. It started the night before in the Bronx.

Pete Alonso Made a Costly Error Against the Yankees

In the eighth inning of the Subway Series finale, with the score tied 2–2 and the Yankees threatening with runners on second and third and one out, Jordan Vivas hit a sharp grounder to first. Pete Alonso came up firing toward the plate, but once again, the throw was off the mark. It sailed well over catcher Francisco Alvarez’s head, allowing Jasson Domínguez to score the go-ahead run.

That opened the floodgates. Paul Goldschmidt followed with an RBI single, Trent Grisham walked to load the bases, and after Genesis Cabrera struck out Aaron Judge, Cody Bellinger crushed a grand slam to right. A tight game unraveled into an 8–2 loss.

“I messed it up,” Pete Alonso admitted postgame. “I just made an awful throw. That whole inning, this game, it’s on me. After that throw, the momentum got out of hand and they had really good at-bats and this one’s on me.”

If Sunday was the tipping point, Monday was the outburst.

After his wild throw against Boston, Pete Alonso kept his emotions in check on the field but took it out on his gear once he reached the dugout, his glove bearing the brunt of it. Even a clean, routine 3–1 putout in the sixth inning came with a called-for celebration and visible relief. For once, the throw went where it was supposed to.

Still, the Mets fell again, and with it, their grip on the NL East lead. The Phillies now sit atop the division, with the Mets trailing by half a game. A challenging series against the Dodgers looms.
