Serena Williams slugged her way to a sixth Wimbledon singles title Saturday morning, completing her second so-called "Serena Slam" and positioning herself for tennis history.
The 33-year-old American defeated Garbine Muguruza of Spain, 6-4, 6-4, to win her fourth consecutive Grand Slam tournament, beginning with last year's U.S. Open and including this year's Australian and French open titles. She accomplished a similar sweep in 2002-2003.
Williams is now poised to equal some of the greatest marks in tennis six weeks from now at the U.S. Open in New York:
- A calendar-year sweep of the major tournaments has only been accomplished three times and not since Steffi Graf did it in 1988.
- Williams can also match Graf's Open-era record of 22 Grand Slam singles titles.
- A seventh title would break a tie with Chris Evert for most U.S. Open wins.
The U.S. Open begins Aug. 31 in Flushing Meadows, New York.
