Can qualifier Sonego slow a rising Quentin Halys?
Sonego v Halys Match page ›A climber against a slider
Can Sonego, who has had to qualify this week and has slid on Predictionist's ratings, stop Halys, who has been climbing all season? That's the question on Tuesday in Stockholm, and it's the first time they've met.
Predictionist's ratings are its own list, separate from the ATP rankings, and they put real distance between the two men. Halys is No. 80 and Sonego is No. 222, so Predictionist sees Halys as the stronger player right now. The direction matters too. Sonego has fallen since the start of the season and Halys has risen. The biggest factor in Predictionist's number is that gap in ratings, and the serve also favours Halys.
Sonego has already played here
Having to qualify doesn't mean Sonego is short of match play. He has already won two matches in Stockholm, both in straight sets: 6-4 7-6 over Olle Wallin on Saturday, then 7-5 6-3 over Inaki Montes-De La Torre on Sunday. That's four sets on these hard courts.
Halys arrives from Paris. His last match was a 7-6 6-4 loss to Tommy Paul in the round of 16 of the Paris Masters on 5 November. It was a close defeat.
The serve gap is thin
This is where Sonego has his best argument. Halys holds 86% of his service games, 4 points better than the typical player on tour, so opponents rarely get a break against him. Sonego holds 82%, about tour average. Halys is the steadier server, but only slightly.
Predictionist's projection for this match points the same way: Halys winning 72% of points on serve, Sonego 70%. That's a slim gap, and it leaves Sonego well within reach. Halys's edge is that he gives up fewer service games. If Sonego matches that, the ratings gap counts for less than it looks.
Tiebreaks won't split them
If both servers hold well, a tiebreak is a real possibility, and neither record points clearly to one side. Halys is 26–18 in tiebreaks this season, Sonego 11–8. Both are winning records, though Sonego's comes from fewer than 20 tiebreaks, so it's a hint rather than a pattern.
They haven't met before, so there's no history showing how their games fit together. All we have is what each has done against everyone else.
Our lean
Halys deserves to be the favourite, and Predictionist gives him a 60% chance, mostly because of his higher rating. But Sonego's serve is close enough to Halys's that if it keeps pace, this is closer than that number suggests.
What to watch
Whether Sonego's service games come as easily as Halys's, because the margin between them is so slim.
