Leylah Fernandez will be trying to win her first WTA title of the season, and Anna Kalinskaya will seek the first of her career when they meet each other in the final of the hard-court DC Open.

Three hours 12 minutes later, Leylah Fernandez, glistening with sweat from the marathon she had survived, could finally throw her arms in the air. She had been pushed to the brink and somehow returned from it.

Leylah Fernandez battled back to upset Elena Rybakina and Anna Kalinskaya ousted a resurgent Emma Raducanu to set up the DC Open final.
