Tennis: Serena Williams tops Ivanovic in US Open 4th round
AP, Monday 5 Sep 2011
Serena Williams needed just 74 minutes to return to the U.S. Open quarterfinals, beating 2008 French Open champ Ana Ivanovic in straight sets

Williams won 6-3, 6-4 on Monday to move on to face Anastasia Pavlyuchenkova in her first major quarterfinal since missing nearly a year with a series of health problems.

The 16th-seeded Serb actually had more winners Monday. But Williams minimized her mistakes on a windy afternoon in Arthur Ashe Stadium, with 14 unforced errors to Ivanovic’s 29.

Ivanovic had eight double-faults in the blustery conditions.

The 28th-seeded Williams is a three-time U.S. Open champion.
