After more than two years off the calendar, the J.P Morgan Tournament of Champions is back, live from New York's Grand Central Station.
Home player, Sabrina Sobhy opens the tournament as she faces England's Millie Tomlinson on the glass court. Sobhy reached the last 16 in this event last time and will be looking to build on that performance in this year's event.
The two winners of the J.P Morgan Tournament of Champions Challenger event will be in action on day one as USA's Timothy Brownell and Hong Kong's Chan Sin Yuk will take on Karim El Hammamy and Zeina Mickawy for a place in round two.
