"Bro thinks it's the world series" "Grown man deadlifting a plate???" - MLB twitter fans mock All-Star Pete Alonso's bizarre workout before Home Run Derby

Pete Alonso of the New York Mets was caught deadlifting 135 pounds while wearing his uniform just before taking the field at this year’s Home Run Derby. The video was posted shortly before Alonso took the field for his first-round showdown against Ronald Acuña Jr. of Atlanta Braves.

Alonso is a first baseman of the New York Mets. He defeated Acuna in the first round but lost to Julio Rodríguez in the second round, ending his two-year reign as Home Run Derby champion.

On the contrary, an Alonso fan defended the athlete and disclosed that “he’s competing for something bigger than himself.”

"If you didn't hear his interview, he's competing for something bigger than himself." - Evan Creager

When asked about the heavyweights, Alonso explained:

"That's not really heavy weights; it was just more me getting activated. I just wanted to get everything kind of firing the right way, get the body warmed up. That's typical for pregame and stuff like that." – PAlonso

Pete Alonso also revealed his rules to win a Home Run Derby. According to Alonso, staying hydrated is a success mantra.

“I always try and be the most hydrated person I can be because when you're out here sweating, especially now in the summer, it gets to be a lot. And then you start feeling fatigued if you're not [hydrated]. So I just want to be able for my body to bounce back, recover and be able to sustain a high energy output." – PAlonso

Alonso believes in laughing at the bad swings and enjoying the game to the fullest.

"I'm there to win. I'm doing it to win, and it'd be great, but ultimately I'm gonna be having a wonderful time. I'm gonna be able to help support some people in need. It's gonna be a blast." – PAlonso

All-Star events do allow players to relax a bit and enjoy the sport they love.
