Poland’s Jerzy Janowicz, who has reached his first Masters Series semifinal at the Paris Masters by upsetting Top 10 players Andy Murray and Janko Tipsarevic along the way, describes his remarkable roll.

“I slept very well two hours, so no problem to sleep whatsoever," the 6'8" Pole told reporters. "I stayed on my computer for a few hours. I went to sleep at 5 a.m. As I can see, it doesn't matter if I sleep. I don't eat. Right now I'm playing the best tennis my life."  
The 21-year-old came into the tournament ranked No. 69 after reaching his maiden quarterfinal in Moscow two weeks ago.  
"I was bad boy at school, primary school,” he said. “High school I was fighting with everyone, with teachers. I was a really bad guy. Somehow it's really not easy for me to explain why I'm that kind of guy.”
