Justin Bieber
This isn’t quite the worst pitch of all time, but the fact that the Biebs was on the mound waving off calls that the catcher wasn’t even giving him was pretty awkward. Mark Buehrle was confused behind the plate wondering if he should give him an actual sign or just wait to catch the ball. What may have also made this a bad pitch is that Justin is left-handed, but he tossed the pitch with his right hand instead.
Ambidextrous, maybe?
