Former professional baseball player Alex Rodriguez took to social media on Thursday to document his afternoon coaching Kim Kardashian and other members of her famous family in a friendly sports matchup.

Dubbed the “Calabasas Peaches,” Kim, Khloe Kardashian and Kris Jenner suited up in black, white and purple uniforms for the big game. Of course, it’s probably safe to assume KoKo cheered from the sidelines, as she’s eight months pregnant with her first child.

A-Rod shared multiple snapshots to Instagram Stories, one of which featured Jennifer Lopez’s beau showing Kris how to hold a bat as Kim watched intently. 

 “These Calabasas Peaches can hit! #runforyourlife,”  

Kim, Kourtney and Khloe Kardashian suited up for a baseball game in Calabasas. The sisters appeared to have a great time, shooting scenes for their show, Keeping Up With The Kardashians.  Expect to see the game on an upcoming episode of Keeping up with the Kardashians.
