Philadelphia Phillies star Bryce Harper and wife Kayla have welcomed their fourth child, Hayes Three Harper, ahead of Saturday's playoff opener. The Harpers shared the news on Instagram, announcing their son was born Thursday. Harper, a two-time National League MVP, was in the lineup for Game 1 of the NL Division Series against the Los Angeles Dodgers. Earlier in April, Harper used a blue bat for a gender reveal during a game. Harper and Kayla already have three children: a son named Krew and two daughters, Brooklyn and Kamryn.
