Somewhere, Koji Uehara is green with envy.

Koji’s reign as Boston’s high-five king might be in jeopardy after the slap that Stephen Drew dished out Monday. Drew went hand-to-flipper with a 20-year-old, 210-pound male harbor seal named Reggae at the New England Aquarium, according to The Boston Globe.

Drew and his family apparently became regulars at the aquarium during the shortstop’s first season in Boston. It’s unclear, however, whether Drew and Reggae have given each other daps before.
