Rory McIlroy has no idea how he wound up topless in a kilt after Ryder Cup win

Rory McIlroy’s memory of stripping down to his waist, donning a wig and a kilt, and partying with the U.S. team after he and his European mates vanquished their Ryder Cup opponents on Sunday is a tad hazy.

“Honestly, honestly, I don’t remember,” McIlroy, laughing, said Wednesday on the eve of the Alfred Dunhill Links Championship. “The time line sort of gets a bit fuzzy about midnight.”

Thanks to social media, the world No. 1 need look no further than Twitter to jostle the alcohol-depleted brain cells that apparently blocked out McIlroy’s recollection of how (perhaps more important, why) he put on the tartan duds and lovely red hairpiece.

McIlroy, who shanked his first post-Ryder Cup tee shot in Thursday’s opening round at Carnoustie (via Bernie McGuire), was better able to cobble together how he made his way into the opposition’s lair after the 16.5-11.5 rout and much liquid celebration. Seems the four-time major champion was whooping it up with his parents and pals in the bar when he received a message on his cell phone.

“I got a text from Keegan Bradley about 10:30 that was very funny, basically just inviting me to the U.S. team room,” McIlroy told reporters gathered for the European Tour event. “So I said, ‘Yeah, I’ll go in.’”

It’s unclear whether the kilt and wig adorned McIlroy’s buff body when he approached the area, though we’re guessing the costume party was Bubba Watson’s idea.

In any case, two security guards, who greeted the leader of the Euro squad at the door, told McIlroy they believed Tom Watson’s defeated band was not entertaining visitors at the moment. We’ll let Rory, who explained he was there at the invitation of the guys in the room, give the play-by-play from here:

“I said, ‘What are you talking about?’ He said, ‘Let me go in and check,” McIlroy said. “So I’m standing here at the U.S. team room door for five minutes, just felt so strange.

“He said, ‘No, they are not letting anyone in yet.’ I said, ‘Really?’ He said, ‘Yeah, Patrick Reed said’ ‑‑ I was like, ‘Patrick Reed,’” McIlroy said with a chuckle.

Turns out, McIlroy discovered when he returned to his own turf to find some Americans hanging about, that it was all a big gag.

“They had obviously planned it or whatever, had a good laugh about it,” McIlroy said. “We all piled into the U.S. team room and had a good time with everyone.”

What made him bare his chest and wrap a kilt around his hips will have to remain a mystery.

“I can’t remember much after that other than I ended up in the kilt,” McIlroy conceded, according to McGuire.
