Stanislas Wawrinka, who has reached the ATP World Tour Finals for the first time, tells ESPN.com that one of the reasons he has been so successful this year is because he has been playing the big points better.
“When I get into those points, I am not so nervous,” he said. “It's my career and my life these last few years, and I knew I could be better than a top-20 player every year… Physically, I am at my best; I think I have two, three years to be at my best. I’m really looking forward to next year to see where I can take myself.”
