The Chicago Cubs have become the first team in Major League history to have five players record at least 20 home runs in their age-25 season or younger.

Ian Happ, 23, homered against the Pittsburgh Pirates on Wednesday to join Javier Baez (age 24), Kyle Schwarber (24), Willson Contreras (25) and Kris Bryant (25) in the club.

"That's pretty impressive. That's never been done, right? That's a long time," Joe Maddon said.
