Maria Sharapova will take the court Friday night at the U.S. Open in New York, the latest step in a return to the court for the five-time Grand Slam champion following a 15-month ban by the International Tennis Federation (ITF) for taking the banned substance meldonium.

Sitting in the Russian tennis star’s personal box will be Fox Rothschild litigation co-chair John Haggerty, who was also in attendance on Monday when Sharapova beat No. 2 ranked Simona Halep in her first official match in 19 months.
