Women's second seed Agnieszka Radwanska won 10 straight games as she recovered to beat Carla Suarez Navarro of Spain 4-6 6-3 6-love in a second-round battle at the US Open Championship in New York.
The Wimbledon runner-up looked in trouble when world number 39 Navarro was serving at 3-2 in the second set but Radwanska hit back to claim victory after one hour and 57 minutes.
In a gruelling match containing a series of long rallies, Suarez Navarro took the attack to Radwanska and the Pole in trouble for a set and a half.
But when she broke back for 3-3, everything changed and she reeled off the next nine games to set up a meeting with former world number one Jelena Jankovic of Serbia.
