Emma Raducanu could face four-time Grand Slam champion Naomi Osaka in the second round of the Washington Open if the pair win their opening matches.
Raducanu is playing for the first time since her agonising third-round Wimbledon defeat to Aryna Sabalenka and will play Ukraine's Marta Kostyuk in the first round, which begins on Monday - live on Sky Sports Tennis.
Fellow Brit Katie Boulter has a tough draw against Greece's Maria Sakkari, then would play second seed Emma Navarro in the next round.
Raducanu and Boulter are in line to meet in the quarter-finals, should they reach that stage of the WTA 500 tournament, and are building up to the final Grand Slam of the year - the US Open, which is live on Sky Sports from August 24 to September 7.

The top four seeds - Jessica Pegula, Navarro, Elena Rybakina and Clara Tauson - have received a bye to the second round.
Venus Williams is back on the tour after 16 months out of the sport and has accepted a wild card for the Washington Open.
Williams, the older sister of 23-Grand Slam winner Serena, will play compatriot Peyton Stearn in her first match since March 2024.
The 45-year-old won seven Grand Slam titles between 2000 and 2008, five of which came at Wimbledon.
Paula Badosa will not defend her Washington Open title due to a lower back injury.
Evans and Norrie lead British men's hopes
Dan Evans has also been given a wild card after winning the 2023 Washington event and will play Belgium's Zizou Bergs in the first round.
Evans is back in the top 150 on the ATP rankings after re-finding some good form on the grass, despite being thrashed by Novak Djokovic in the second round at Wimbledon.
Cameron Norrie made the quarter-finals at the All England Club and will play a qualifier in Washington, before facing second seed Lorenzo Musetti if he wins.
The men's draw features 48 players, compared to the women which has 28, so the top 16 seeds, led by Taylor Fritz, get a bye into the second round.
Holger Rune, Ben Shelton, Andrey Rublev, Frances Tiafoe, Alex de Minaur and Daniil Medvedev make up the top eight of those seeds along with Musetti and Fritz.
