Teel made his major league debut on Friday night for the Chicago White Sox and his former teammate Marcelo Mayer had a nice message for him on Instagram.

The Chicago White Sox have called up another one of their top prospects, catcher Kyle Teel. To make room, they've sent down another young catcher to AAA Charlotte, Korey Lee. Teel will start behind the plate while batting sixth on Friday night in his Major League Baseball debut against the Kansas City Royals.
