Will the player from Kempen capitalize on the Greek player’s slump in form?
In a thriller that lasted five sets, Daniel Altmaier prevailed against Hamad Medjedovic after almost five hours, converting his first match point and advancing to the second round of the US Open for the second time in his career. On paper, he is now the clear underdog there. However, on closer inspection, it becomes apparent that in Stefanos Tsitsipas vs. Daniel Altmaier, the prediction that the Kempen native will now even make it to the third round is not so far-fetched. After all, the Greek is in a serious slump.
Since the 2024 French Open, when he beat Daniel Altmaier in the second round, Stefanos Tsitsipas has never made it past the second round of a Grand Slam tournament. Most recently, he was eliminated in the opening match at Wimbledon. In the run-up to the US Open, the Greek lost five of his last six singles matches – including the final preparatory tournament in Winston-Salem, where he made 33 unforced errors and lost 0-2 to underdog Bu Yunchaokete (ATP 76). However, as betting on another Tsitsipas defeat is a little too risky, we have decided to go with a handicap of +1.5 sets on the German as our main recommendation.
It is clear that the momentum is with the German, whose form has been similarly disappointing since Roland Garros, but who remained cool in his opening match, winning 81 percent of points on his first serve and breaking his opponent’s serve five times. Daniel Altmaier made only 24 unforced errors (compared to 64 for Hamad Medjedovic), which could also be the key to success against the Greek.
We expect a match that, just like the last meeting between the two players, is unlikely to be decided in three sets and has the potential to go the full distance. A good bet in Stefanos Tsitsipas vs. Daniel Altmaier, at odds of 1.58, which we found in the Bet365 app, is that at least one set will be decided in a tiebreak.
Stefanos Tsitsipas – Daniel Altmaier Head-to-head record
Head to head: 1:0
The two players have only crossed paths once before. That encounter also took place in the second round of a Grand Slam tournament, but in the 2024 edition of the clay court classic in Paris. At that time, Stefanos Tsitsipas prevailed 3-1 in a very close match against Daniel Altmaier, who now wants to get his revenge a year and a half later.
Stefanos Tsitsipas – Daniel Altmaier Tip
Our prediction for Stefanos Tsitsipas vs. Daniel Altmaier leans very cautiously toward the Kempen native, who now faces an opponent who, once a firmly established top 10 player, has fallen to 28th in the ATP world rankings in the wake of a prolonged slump in form. Before his 3-1 opening victory against Alexandre Müller (ATP 38), the Greek lost five of six consecutive singles matches. He has not won two consecutive matches on the ATP Tour since April, and recently ended his collaboration with coach Goran Ivanisevic, who had publicly criticized his protégé, describing him as “unprepared.”
It is therefore quite possible that the supposed underdog Daniel Altmaier will now capitalize on the Greek player’s slump in form and advance to the third round of the US Open for the first time in his career. Since a direct bet on the Kempen native is a bit too risky for us, we are placing a handicap of +1.5 sets on him, which would also cover a 3:2 victory for the Greek.
The betting odds for Stefanos Tsitsipas against Daniel Altmaier are 1.90, which we are betting on at Interwetten with three out of ten units.
