Serena Williams vs Agnieszka Radwanska

Head-To-Head: serena vs radwanska 8- 0

Serena is playing her milestone 30th Grand Slam semifinal.
And she's gone 25-4 in the first 29. The losses? Venus williams at 2000 Wimbledo, henin at the 2003 French open, clijsters at the 2009 US open and Roberta Vinci at the 2015 US open.

Nobody's done more winning since New York than Radwanska.
Radwanska has won more matches (27) and more titles (4) than anyone on the tour since the US open . She left New York ranked No.14 and is now No.4 - and she'll be No.2 if she makes the final.

Serena has never lost a semifinal here - or a final.
Serena is 6-0 in australian open semifinals and 6-0 in australian open finals, too. She did have to save match points in two semifinals though (Clijsters in 2003 and Sharapova in 2005).

Radwanska has beaten a World No.1 before.
In 2012, Radwanska defeated wozniacki in Sydney to become the first Polish woman ever to beat a reigning World No.1. She's 0-4 against Serena while the American's ranked No.1, though.
