US Open: Day four

Radwanska through to third round

Radwanska 7-6 6-3 Broady

Agnieszka Radwanska speaking on court: "I'm so pleased I could come back in that first set. It was the key set. There was a lot of running and a lot of struggling but it was another two sets for me, so yay!

Radwanska on Broady: "She was serving unbelievable. 120mph serves are not easy to return."

Game, set and match Radwanska

That's it - Radwanska prevails. What a fight from Britain's Naomi Broady, though. 

Another speedy session on Radwanska's serve. 

She holds to love again, as Broady sends a skewed forehand way past the bottom corner of the court.
