Phillies' Bryce Harper welcomed son Hayes Three on Oct. 2, then played in Game 1 of the NLDS on Oct. 4.

Phillies outfielder Bryce Harper and his wife Kayla welcomed their fourth child, son Hayes Three Harper, on October 2, 2025, just days before Game 1 of the NL Division Series against the Los Angeles Dodgers. The couple announced the birth via a joint Instagram post, joking about adding "more chaos to Red October." Harper, a two-time NL MVP, started in the Phillies’ playoff opener on October 4, continuing his season despite the personal milestone. The family already has three children: sons Krew and Hayes Three, and daughters Brooklyn and Kamryn. The announcement coincided with the Phillies’ postseason debut, highlighting Harper’s dual focus on family and baseball.
