Phillies' Bryce Harper, Wife Kayla Announce Birth of Son Hayes in Photo Before NLDS

Philadelphia Phillies superstar Bryce Harper and his wife, Kayla, announced the birth of their fourth child, son Hayes Three Harper, on social media Saturday.

"Decided to add more chaos to Red October," Kayla Harper wrote in an Instagram post.

The news dropped as the Phillies are getting ready to host the Los Angeles Dodgers in the National League Division Series.

Harper, who is the father of a six-year-old son, a four-year-old daughter and a 17-month-old daughter, has made it a habit of hitting home runs after the birth of his children.

Harper helped lead the Phillies to a 96-win season and their second straight NL East title. The eight-time All-Star and two-time National League MVP hit 27 home runs to go along with a .261 average (.844 OPS) and 75 RBI.
