NEW YORK - Serena Williams needed a medical time out in the second set of her 6-3 6-4 win over Petra Martic on Sunday to get treatment on her right ankle but recovered to advance to the U.S. Open quarter-finals.

Williams fell to the court at 2-2 in the second set after charging to the net to hit a volley that sailed long.

The 37-year-old America Serena Williams and eighth seed got treatment on her ankle during the changeover and appeared to be fine, smacking 38 winners on a sunny day at Arthur Ashe Stadium court.

Williams blasted her fourth ace on match point to see off 28-year-old Croatian Martic and reach the last eight, where she will face Wang Qiang of China for the first time.
