The outfielder could've blamed lack of sleep for his mistake. The Cubs were playing a few hours after a 16-inning marathon game that ended shortly after 1 a.m. ET Thursday. Lake headed to left field with a grey road top, but it said "Chicago" across the chest. The new version, which all his teammates were wearing, says "Cubs."
Grimm was in the bullpen, which is in left-center at PNC Park, and noticed Lake's fashion faux pas.
"[Grimm] said, 'Hey, you got the wrong jersey,' and I looked," Lake said. "I thought he was joking. When I looked, I saw everybody [wearing the other jersey]. I said, '[Darn].' I said, 'What the [heck] is going on?'"
The clubhouse staff normally hangs that day's game jersey in an obvious spot in the locker.
"I see two grey, and I took one," Lake said. "Everybody was in grey, and I took the wrong grey."
Was the problem a lack of sleep? Unfortunately, no.
"I slept seven hours," Lake said.
Lake dashed into the clubhouse after the first inning and changed into the appropriate top.
