The quarterfinals of the ATP 250 in Delray Beach bring a packed slate of matches that, remarkably, sees six of the eight seeded players reach this stage, with five Americans making up the final eight. As always, we here at LWOT will be predicting every match, but who do you think will win?

ATP Delray Beach Quarterfinal Predictions
Coleman Wong vs Flavio Cobolli

Head-to-head: First meeting

This has been a very important week for both players, who entered the tournament short on match wins and confidence. Now, with some momentum behind them, I expect each to fully commit to his game style in this match, with Coleman Wong looking to rely on his serve and first-strike groundstrokes, while Flavio Cobolli aims to make this a physical baseline battle. Ultimately, the Italian has more pedigree at this level and should reach the semifinals here.
Prediction: Cobolli in 2

Casper Ruud vs Sebastian Korda

Head-to-head: Ruud 2-0 Korda

Casper Ruud and Sebastian Korda meet in what looks like an exciting matchup on paper between two high-quality players with contrasting styles. Ruud will look to dictate play with his forehand and capitalize on any return opportunities. On hard courts, Korda will be comfortable counterpunching, using his fluid groundstrokes and strong serve to control rallies. Nerves and fitness can sometimes concern the American, but if Korda manages both well, he has the tools to produce a seeding upset.
Prediction: Korda in 3

Frances Tiafoe vs Learner Tien

Head-to-head: Tiafoe 1-0 Tien

An all-American clash in front of a home crowd always carries a unique atmosphere as Learner Tien faces Frances Tiafoe for a place in the semifinal. Tiafoe endured a disappointing 2025 season but has shown signs of improvement this year. Tien, however, is developing rapidly, and with his improved serve complementing a highly tactical baseline game, he may have what it takes to secure the win.
Prediction: Tien in 3

Taylor Fritz vs Tommy Paul

Head-to-head: Fritz 3-2 Paul

Taylor Fritz and Tommy Paul headline the day in what should be a tightly contested encounter. Both are strong baseliners, but approach matches differently. Fritz prefers to dictate with aggressive groundstrokes, while Paul looks to extend rallies and rely on his movement and counterpunching. Fritz has admitted to dealing with knee issues to start the year, and in a close battle against the better mover and defender, that could prove decisive.
Prediction: Paul in 3
