The song “September” by Earth, Wind & Fire played from the Camden Yards loudspeakers each time Pete Alonso stepped to the plate on Monday night. *“Do you remember, the 21st night of September?”* Alonso remembers the night of Sept. 21, 2025, quite well. It was when he became a father, with his wife, Haley, giving birth to their son, Teddy. “That was for him,” Alonso said of Monday’s musical shakeup. “That’s his birthday song.” Celebrating Teddy’s first birthday, Alonso should always remember the night of Sept. 21, 2026, as well. Alonso clubbed his 39th and 40th homers of his first season and lifted the Orioles to a series-opening 4-3 comeback win over the Blue Jays. The 31-year-old slugger’s second blast was a go-ahead two-run shot with two outs in the bottom of the eighth inning. Happy Birthday to Teddy, indeed. “It's obviously special,” Alonso said. “Hopefully, we can bookmark this game. I know it doesn’t matter now, because he’s not going to understand it for a couple years. But hopefully, a couple years down the line, I can kind of look back and just kind of bookmark this and keep it for the archives, and then hopefully, he appreciates it one day.”
