Serena Williams on Illustrated Sport Magazine cover issue

Serena Williams is on the front cover of Sports Illustrated Magazine, sixteen years after she first appeared.

For the first time in her career, the world No. 1, superstar who will turn 34 years old a month from Wednesday, is in the running for a chance to win a calendar Grand Slam, which would make her the first player to accomplish the feat since Steffi Graf in 1988.

If Serena takes home the U.S. Open title, it would mark her FIFTH straight Grand Slam title and her FOURTH consecutive U.S. Open title.
