Gabriel Diallo has a chance at redemption against Taylor Fritz in the National Bank Open on Friday.
The pre-match narrative: Fritz bested Diallo in an epic five-set Wimbledon showdown last month and is favoured to win the rematch. Diallo, the last Canadian in the Toronto draw, will need to neutralize the American’s big serve to advance to the final 16.

Best men’s tennis pick
Best bet: Fritz -3 games (-120)
Fritz is at the top of his game right now, and he looks to keep things rolling after a spectacular grass season.
The American picked up two titles overseas (Eastbourne International, BOSS Open) and advanced to the Wimbledon semifinals before losing to two-time champion Carlos Alcaraz.
It’s hard to imagine Diallo exacting some revenge, given his hard-court struggles against top-level opponents.
- Diallo is 0-6 on hard court against top-20 ranked players, losing three of those matches by 3+ games.
- Two of the other top-20 hard-court losses were at Grand Slams, where he lost in four sets both times.
- The other was against Arthur Fils, and Diallo was forced to retire after losing the first set, 4-6.
Fritz ranks first on the ATP Tour in service rating (296.3) and first-serve points won (79.3%). He also ranks second in service games won (89.3%).
Diallo has a big serve of his own but is a pedestrian 58th in return games won (18.8%). He just lost, 3-6, 2-6, to another American, Ben Shelton, at the Citi DC Open.
Key stat: Fritz’s 67.09% win rate on outdoor hard courts is his best of any surface. He is 9-2 on hard courts since the start of the Indian Wells Open, covering a -3.5 game spread in seven of those matches.
