Three popular Canadian tennis players are in action in the first round at Wimbledon on Monday.
The pregame narrative: The yearly Grand Slam major played on grass begins with Felix Auger-Aliassime taking on James Duckworth. Gabriel Diallo also gets his tournament started on Monday against Daniel Altmaier.
Check out my top Wimbledon predictions for the June 30 tennis matches, featuring a pick on Leylah Fernandez vs. Hannah Klugman.
Wimbledon predictions: June 30
Best Bet: Auger Aliassime -5.5 games (+107)
Auger-Aliassime is having a roller coaster of a season, and he's currently making a climb.
The Canadian went 5-3 on grass in preparation for Wimbledon and advanced past the first round in all three of the events.
He lost to some quality opponents, but the good news for this matchup is that he's comfortably taken care of lower-seeded players.
That brings me to Duckworth, who is currently ranked No. 106 in the world. He's 5-4 on grass, and he hasn't beaten a top 50 player this year on the surface.
On top of that, he's been crushed by Auger-Aliassime in their career meetings. FAA is only getting better, while Duckworth is on the decline at 33 years old.
Key stat: In two meetings since the start of 2020, Auger-Aliassime is 2-0 vs. Duckworth, winning all five sets. The Canadian covered this line in their one career Grand Slam matchup (6-4, 6-1, 6-2).
Diallo Wimbledon prediction vs. Altmaier
Diallo under 21.5 games won (-122): The 23-year-old from Montreal is shaping into a very good player on grass.
- He's 8-2 on the surface this year.
- He won his first-ever ATP singles title on grass at the Libema Open in June.
He doesn't have the best history against Altmaier, losing both matches, but they've never played on grass. I predict that to be a huge factor in this chapter.
And that's because it's easily the German's worst playing surface. He's never finished a season with a win rate above 50% on grass and holds a 9-16 career record on the surface.
Altmaier has won more than 53% of his matches on every other surface, so it's a clear weakness for him.
Expect Diallo to use his long, powerful frame to push a pace early that his opponent won't be able to match.
The Canadian has held 91.2% of his service points on grass this season. This is a good way of backing Diallo to win in straight sets with three games of insurance to work with.
Best bet for Fernandez vs. Klugman
Fernandez/Klugman under 18.5 games (+106): Of all the Canadians on the women's side, Fernandez got the best draw.
Her 16-year-old counterpart will be a great player one day, but she isn't ready for Wimbledon yet.
Klugman went 6-3 on clay this season, but her 0-2 start on grass has followed a familiarly bad trend.
In her short career, the English tennis player is 4-12 on the surface. She does her best work on the red dirt but also has a winning record on all other court types.
Both of Klugman's matches on grass were played on the WTA tour, so it's comparable competition to what Fernandez will provide.
She managed to win just 10 games across those two matches, with both going under this total.
Fernandez is coming off a competitive outing (7-6, 7-6) against Jasmine Paolini (No. 4). She fell short in the matchup but looks to be in good form heading into London.
