WATCH: Serena Williams Does Split in U.S. Open Match

Serena Williams was chasing down a shot by Taylor Townsend along the baseline during Tuesday night’s first-round U.S. Open match when the 18-time Grand Slam champ showed off some flexibility while going into a split.

Williams is favored to win the women’s draw after winning the Western & Southern Open in Cincinnati to break out of a summer-long slump.
