Defending champion Stan Wawrinka avoided a repeat on Wednesday of his first-round scare, though he was still made to work hard in a straight-sets win over Japan's Taro Daniel. The Swiss third seed won 7-6(7) 6-3 6-4 and is now on a six-match winning streak on clay, having warmed-up for Roland Garros by winning the title in Geneva last week. Progress was by no means straightforward against a skilful opponent ranked 93rd in the world and Wawrinka has yet to switch to his A game. But he says it's there when he needs it. "If you look at the first two matches, for sure I'm not playing my best tennis, but I know I have my best tennis in me," the 31-year-old Wawrinka, playing in his 45th consecutive grand slam tournament, told reporters.
