The third round in Cincinnati has thrown up some intriguing matchups, with players coming in from very different trajectories. Some have built confidence with strong showings in recent weeks, while others are still looking for the spark to turn their summer around. The fast courts and humid conditions are adding an extra layer of unpredictability, so expect plenty of momentum swings and tight scorelines across the board. As always, we here at LWOT will be offering our predictions for every match on the schedule. But who will advance?

ATP Cincinnati Day 5 Predictions

Frances Tiafoe vs Ugo Humbert

Head-to-Head: Tiafoe 2–1 Humbert

Frances Tiafoe and Ugo Humbert meet with both having put in solid performances recently, though in contrasting ways. Tiafoe’s quick-strike game has been clicking at times during the hard court swing, while Humbert has showed great composure from the baseline in his first match since Wimbledon in the previous round. Their head-to-head has Tiafoe in the lead, and with both players in decent rhythm, this could come down to who manages their service games better.

Prediction: Tiafoe in 2

Arthur Rinderknech vs Felix Auger-Aliassime

Head-to-Head: Auger-Aliassime 1–0 Rinderknech

Arthur Rinderknech has been building quietly, picking up some good wins since the grass swing, and now faces Felix Auger-Aliassime, who’s enjoying one of his best patches of form this year. Felix has been moving well and dictating play with his forehand, but Rinderknech’s serve-and-volley skills could keep the rallies short and the pressure high. The clash of styles will make for an engaging affair but the Canadian should have too much for his opponent. Rinderknech comes off his third top 20 win of the season, as he beat Casper Ruud in round 2.

Prediction: Auger-Aliassime in 3

Adrian Mannarino vs Tommy Paul

Head-to-Head: Mannarino 1–1 Paul

Adrian Mannarino and Tommy Paul are no strangers to each other, having shared some tricky battles in the past. Mannarino’s flat strokes and ability to redirect pace can trouble anyone, especially on a quick court, while Paul’s athleticism and counterpunching have carried him deep in recent events. If both bring their A-game, expect a match full of sudden shifts and long, absorbing exchanges.

Prediction: Paul in 3

Gabriel Diallo vs Jannik Sinner

Head-to-Head: first meeting

Gabriel Diallo’s dream run meets a stern test against Jannik Sinner. The Canadian has been playing freely, feeding off the crowd and striking the ball with confidence, but Sinner’s recent form and big-match experience make him a different challenge altogether. If Diallo can keep up his aggressive serving and take time away, he might just make things interesting.

Prediction: Sinner in 2
