Let the (mind) games begin!

The Yankees did some team bonding on Friday, getting in a group session with celebrity hypnotist Ricky Kalmon amid spring training in Tampa.

According to The Athletic, the activity was organized by manager Aaron Boone and director of mental conditioning Chad Bohling, with all the players, coaches and front-office personnel getting involved.

Though it appears the team did indeed get very, very sleepy, we just hope Boone took some notes on how to get the Red Sox to think they’re chickens at crucial points during games this season.
