Junior Lake wore the wrong road jersey as the Chicago Cubs took the field for the first inning of Thursday's game against the Pittsburgh Pirates.

The Cubs have two gray road jerseys this year -- one with "Cubs" written across the front, the other with "Chicago" written on it.

They wore the "Cubs" jersey on Thursday, but Lake trotted out onto the field wearing a "Chicago" one.

"Bullpen guy [Justin Grimm] told me I had the wrong jersey. I looked and said [f---]," Lake said after the game.
