PITTSBURGH -- Chicago Cubs outfielder Junior Lake wore the wrong road jersey as his team took the field for the first inning of Thursday's 3-2 victory over 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 during their entire three-game series with the Pirates, but Lake took his place in left field for the final game of the series wearing the jersey that said "Chicago" on it.

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

After the Pirates' final out in the bottom of the first inning, Lake immediately went into the clubhouse to change. He said he got confused because both jerseys were hanging in his locker, and he chose the wrong one.

"Everyone looked at me," he said. "I see two gray, I take the wrong one."

Lake, who finished the game 1-for-4, batted in the top of the first inning wearing the wrong jersey. Manager Rick Renteria was unaware of the mistake until after the game.
