With Joe Mauer at the plate in the 10th inning of Sunday's Twins-Tigers game, Jose Valverde practiced the pull-out method of pitching:

Valverde: And heeeere's the pitch
Valverde: Wait where did it go
Valverde: Oh my hand is still holding it
Valverde: Well played, Mauer

Valverde held on to the baseball, and there was no one on base, so it wasn't a balk or a ball. As far as the statistical record is concerned, it never happened. But we won't forget.
