Tsitsipas locked himself in room, read books for days after Wimbledon

Stefanos Tsitsipas has revealed that he locked himself in his room, reading books for three days following his first-round exit at Wimbledon.

"I thought about this match a lot," he told press following a win in the first round of singles at this week's ATP event at Washington.

In addition to reflecting on his defeat, the 20-year-old Greek did some reading—a novel and a book on Roger Federer.

"One really interesting book about him," he said.

He's the top seed at Washington, D.C., and began with a first-round singles victory, defeating Tommy Paul in straight sets. Before that, Tsitsipas teamed up in doubles with Nick Kyrgios, an unlikely partnership the pair now plan to repeat in two weeks.

"I think that was very important to refuel, recharge my batteries coming in here. I think that released some pressure," Tsitsipas said, adding it might have helped him in singles. "I was a bit nervous in the beginning. Didn't know what to expect. I'm really happy that I got through that first match."

Tsitsipas is No. 6 in the rankings.
