Is Sascha capable of a surprise?
Not many players can claim to have a positive record against four-time Grand Slam champion Jannik Sinner. However, Alexander Zverev is one of them, which makes this matchup in the Björn Borg Group of the 2025 ATP Finals all the more interesting. The winner is almost certain to reach the semifinals and would then be just two wins away from the coveted major title at the unofficial tennis world championship. A title that Sascha, unlike the Italian, has already won twice (2018 and 2021). This makes it all the more exciting to see whether Jannik Sinner vs. Alexander Zverev is a match where betting on the German underdog might even be a viable option.
Basically, there is no value to be found in betting on the Sextner’s victory in the Sinner vs. Zverev prediction.
Although the last two duels went to Jannik Sinner, Sascha leads the head-to-head comparison with four wins out of seven meetings. He has only been defeated by the Italian without winning a set once. Against this backdrop, we are going to risk predicting that the Hamburg native will take at least one set from the defending champion.
If the German does indeed win a set, it is conceivable that the match will be a long one, perhaps even going the full distance of three sets. Alternatively, with Jannik Sinner against Alexander Zverev at odds of 3.10, which we found at Bet-at-home, you could also bet that more than 2.5 sets will be played before the winner is determined.
After all, the player from Sesto had to fight extremely hard in the first set of his opening victory against Félix Auger-Aliassime, in which he ultimately benefited from the Canadian’s calf injury.
Jannik Sinner – Alexander Zverev Head-to-head record
Head to head: 3:4
The two players have crossed paths seven times so far, with Alexander Zverev still leading the head-to-head record with four wins, although he has lost to Jannik Sinner in their last two encounters – most recently in the final of this year’s Australian Open. Down Under, the Italian rolled over the German 3-0 (6-3, 7-6, and 6-3).
Jannik Sinner – Alexander Zverev Tip
Although the betting odds from the best bookmakers clearly and unmistakably favor Jannik Sinner against Alexander Zverev, the Italian local hero, who won the ATP Finals for the first time in Turin in 2024, has six consecutive victories at the Palasport Olimpico and has won a total of ten of the last eleven matches at the unofficial tennis world championship.
Nevertheless, we believe the German, who is known for being able to rise above himself in such big matches, has a valid chance as the underdog. Writing off Sascha prematurely could prove to be an expensive mistake, especially since the low odds for a victory for the Sextner do not in any way outweigh the associated risk.
This makes the prediction that Alexander Zverev will win at least one set against Jannik Sinner all the more interesting. Although he lost the last two matches against the world number two, Sascha has always won at least one set in six of seven singles matches against the South Tyrolean.
