Female Tennis Player, US Open 2011

In 1970, the US Open became the first of the Grand Slam tournaments to use a tiebreak at the end of a set. The US Open is also the only Grand Slam that continues to use the tiebreak in the 5th set. All the other three grand slams play it out with service games in the 5th set.
Jimmy Connors is the only individual to have won US Open singles titles on all three surfaces, while Chris Evert is the only woman to win on two surfaces.
