2010 U.S. Open First Round Result: Tomas Berdych Falls to Michael Llodra

Frenchman Michael Llodra notched the biggest upset (so far) of the 2010 U.S. Open, beating No. 7 Tomas Berdych 7-6, 6-4, 6-4. Despite what looked like a nagging foot injury, Llodra served and volleyed effectively, winning 48 points at the net.

Afterward, Llodra was asked about his reputation as a practical joker in the locker room. He smiled big.

"It's just my secret," he said.

I think this 2005 story says it all:

Ivan Ljubicic was preparing for his third-round match at the Nasdaq-100 Open on Sunday when he found something totally unexpected in his locker, naked fellow player Michael Llodra.

The French prankster Llodra decided to surprise Ljubicic by taking off his clothes and squeezing into the Croatian's locker, much to the amusement of the other players in the changing rooms.

"I went to open the locker and I was completely shocked," 13th seed Ljubicic told reporters.

"He was looking at me, I was looking at him. I said, 'What the hell are you doing here?'"
