In fact, this is the second year that all MLB teams are donning different looking uniforms for Players' Weekend. You'll also notice the names across players' shoulders - in many cases - isn't the player's actual last name. Instead it's a the player's nickname.

Sonny Grey, pitching in Baltimore on Saturday, had his nickname 'Pickles' across his back name plate.

The pinstripes - although they weren't wearing them - have taken the first three game of the four game series heading into Sunday's series finale with the O's.
