Error-prone Serena Williams makes quarters at Indian Wells

Struggling with her serve and a rash of errors, Serena Williams overcame a slow start to beat Sloane Stephens 6-7 (3), 6-2, 6-2 in the fourth round at the BNP Paribas Open in Indian Wells, California, on Tuesday, extending her winning streak to 14 matches. Williams committed 52 unforced errors and had nine double-faults to go with 13 aces and 31 winners in the up-and-down match played in 90-degree heat. “I’m just trying to find my bearings,” the world’s top-ranked player said. “Little off this week.” Williams set up match point with a 128-mph ace and won when Stephens dumped a backhand into the net, one of her 36 errors. – AP
