Williams and Djokovic march on at U.S. Open

New York: Six months after she nearly died, Serena Williams is closing in on what could be the greatest achievement of her incredible career.

The former world number one stormed into the quarter-finals of the U.S. Open by beating Ana Ivanovic 6-3 6-4 Monday and suddenly the title looks to be at her mercy.

"I'm a person that really hates to lose," Williams said.

"It's really important for me just to look at the mountain and keep climbing it, not get discouraged."
