Alex de Minaur De Minaur deserves plenty of attention as the top seed and defending champion in Washington. However, his recent form and confidence have been below his usual standards, making it interesting to see whether a return to a tournament where he enjoyed success last year can spark a turnaround.
Ben Shelton
Shelton has enjoyed a strong season and should once again be a major threat on home soil. His powerful serve and aggressive game are well suited to hard courts, and he has the quality to remain in contention deep into the tournament.
Taylor Fritz
Fritz has been one of the strongest American performers on home hard courts in recent years and comes into Washington after showing signs of rediscovering his best form. If he can maintain that level, the third seed should be firmly among the title contenders.
Learner Tien
Tien's rapid rise continues, with the young American now seeded fifth in Washington. He could make a big impact during the North American hardcourt swing, and playing in familiar home conditions gives him another opportunity to show how far he has progressed.
Frances Tiafoe
Tiafoe has put together a strong and consistent season and now enters a part of the calendar where he has enjoyed plenty of success in the past. If he can carry his recent momentum into the home hardcourt swing, he could be another player capable of making a deep run in Washington.
