After a historic afternoon for Pete Alonso at Citi Field, the Mets’ star first baseman walked across the street to the U.S. Open to celebrate. 

Jeff McNeil posted a photo to his Instagram story showing himself along with Alonso, David Peterson, Drew Smith and Tylor Megill inside a suite at Arthur Ashe Stadium to take in the action. The trip was Alonso’s second time over at the Open.

The U.S. Open had posted a video on X, formerly Twitter, on Thursday of Alonso trying to hit a tennis ball out of the stadium using a tennis racquet. 

On Sunday, Alonso helped power the Mets to a 6-3 win over the Seattle Mariners and in the process reached 41 homers and 100 RBIs. 

Alonso became just the fifth player in Major League Baseball history to hit 40 home runs three times through their first five seasons.

Additionally, he became the fourth player in franchise history to reach the 100-RBI milestone three times. 

“It’s kind of wild to think about,’’ Alonso told reporters. “It’s happened so fast. It seems like yesterday I was in my rookie season. It means a lot. This place has been extremely special to me.”

Alonso has endeared himself to Mets fans since he arrived on the scene in 2019. 

“He’s special. Through thick and thin, we know one thing and that’s that Pete will walk through the door the same guy every day,” Mets manager Buck Showalter said. “He’s a pleasure to be around. He never has a bad day. He cares about his teammates, he cares about the Mets and to see guys like him have success makes it even more enjoyable.” 

Alonso and his Mets teammates weren’t the only New York athletes at the US Open on Sunday. 

Jets star quarterback Aaron Rodgers was in Flushing along with teammates Randall Cobb and C.J. Uzomah.
