The quarterfinals will be played across two different men’s tennis tournaments on Friday.
The pregame narrative: Jack Draper continues to solidify himself as a top-10 player in the world. He’s a sizable favourite over Brandon Nakashima for their match in London. At the Halle Open in Germany, No. 3-ranked Alexander Zverev looks to fight off a red-hot Flavio Cobolli.
Check out my top tennis predictions for the June 20 matches.
Tennis predictions: June 20
Best bet: Draper -1.5 sets (-129)
Draper has been great this season, owning a 27-7 record with a 75% win rate or better on every playing surface.
That includes a strong 2-0 start on grass where he’s won four of his five sets.
Nakashima, meanwhile, has barely edged his way past recent opponents, and I think his luck has run out.
- The American has played five sets at this event. Three went to a tiebreaker while the other two had 10 or more games played.
- That’s resulted in Nakashima needing almost an hour more of on-court time to reach the quarterfinal.
He should be more fatigued than Draper and he’s the less skilled player in this matchup. Draper beat Nakashima in straight sets on grass (6-3, 6-3) back in June 2024.
Key stat: Nakashima is 0-5 this season against top-15 opponents.
Best bet for Zverev vs. Cobolli
Zverev/Cobolli under 21.5 total games (-106): This is a way to back Zverev while avoiding his -205 pricetag to win in straight sets.
Cobolli’s been good over the past month, winning nine of his last 10 matches.
That one defeat, however, was against Zverev in straight sets on clay at the French Open (6-2, 7-6, 6-1). He dominated two of the three sets, halting the Italian’s run in Paris.
And grass provides an even bigger advantage for the No. 3-ranked player in this rematch.
- Zverev’s 67.7% win rate on grass is almost as good as his 70.5% win rate on clay.
- Cobolli is 5-6 on grass (45.5%) in his career, but is 137-88 on clay (60.8%).
The Italian has started 2025 with back-to-back wins on grass, but needed five hours and 17 minutes to complete those matches.
For context, Zverev needed just over three and a half hours to reach the quarters.
The German should have the legs to fuel his talent advantage on Friday. Everything points to Zverev making quick work of Cobolli.
