Serena Williams into QFs of the bnp Paribas open 2016

INDIAN WELLS, CA, USA
 Top seed Serena Williams endured a few frustrating moments against a resurgent kateryna bondarenko, easing past the qualifier, 6-2, 6-2 at the bnp Paribas open.

Bondarenko came back to tennis just over 18 months ago after giving birth to a daughter, but has been playing some of the best tennis of either of her two careers in 2016, reaching the australian open third round as she slowly creeps back to her former career-high of No.29.

"It definitely wasn't an easy match," Williams told Andrew Krasny during her on-court interview. "She's obviously been a good player in the past, and she knows how to play on big courts against big players. So, it was a good match for me."

In complete control through the first six games, the American lost serve a game from the opening set, and battled through windy conditions and some evident angst through the 72 minute match. In the end, she hit 26 impressive winners to only 22 errors, while Bondarenko hit 13 winners to 21 unforced.
