Serena Williams Hurts Foot, Andy Murray Advances

Serena Williams needed treatment on her right foot while playing doubles Wednesday with sister Venus at the French Open, but the defending singles champion at Roland Garros didn't seem to be in pain or hampered in her movement.

The Williams sisters were on their way to a 6-2, 6-2 first-round win against Jelena Ostapenko and Yulia Putintseva when Serena took a medical timeout in the second set. The trainer taped up her foot and ankle.

The sisters broke serve the next game, with Serena hitting a smash to earn three break points, the first of which she converted with a winner from the net.

Andy Murray was forced to go the distance again at Roland Garros as he ground out a five-set win over French wild card Mathias Bourgue.

Having come back from two sets down to beat qualifier Radek Stepanek in an opening-round match stretched over two days, Murray pulled off another escape act on Wednesday to win 6-2, 2-6, 4-6, 6-2, 6-3.

The world No.2's victory in 3 hours, 34 minutes sets up a meeting with Ivo Karlovic -- the oldest player, at 37, to reach the third round of a Grand Slam for 25 years. Murray has never lost to the Croatian, but this will be their first meeting on clay.

"I need to go and rest, it's been a tough few days," Murray said on court postmatch. "I'm going to have to recover extremely well.

"If I'm to go far at this tournament, you can't play too many matches like this. I'm hoping in the next one, if I win, I can do it a little bit faster."
