Coach and commentator Brad Gilbert on Twitter: "Ladies Day! Waza has been the form player - Vera Z is nothin' but great value. I'm leaning toward the guile of Waza in 2 tight sets. The Heavy Weight-2nd semi-final - Kimmie C vs Venus. At the start of the tourney I was worried about V with the knee... seems to have found her form."

1840: Chilly day at Flushing Meadows, I'm told. Fear not. The action WILL be red hot, trust me. First up we've got Wozniacki v Zvonareva and then it's Williams v Clijsters. At stake - a place in Saturday's showpiece. Excited? You ought to be.

1830: Caroline Wozniacki. Vera Zvonareva. Venus Williams. Kim Clijsters. Four women, two matches, one goal. By the end of tonight we will know the line-up for the US Open women's final. Who's it going to be? Time for some semi-final action...
