The indoor hard courts in Stockholm serve up two intriguing semifinal matches, with a mix of established tour regulars and a genuine surprise package all chasing a spot in the final. Alejandro Tabilo takes on Thiago Agustin Tirante in the first semi, before Taylor Fritz and Lorenzo Musetti renew what has become a genuinely compelling rivalry. Here are my predictions for both matches.
Tabilo leads their head to head record by four wins to one, and he has looked sharp all week in Stockholm. The Chilean came through a testing three set battle against Lorenzo Sonego before putting in a genuinely impressive display against sixth seed Alex Michelsen, winning 7-5 7-6. What stood out in that match was his composure under pressure. He faced seven break points and saved six of them, which tells you everything about where his head is at right now. Reaching his first indoor hard court semifinal at ATP level is a meaningful step for a player who has historically been more comfortable on slower surfaces.
Tirante has had a productive week of his own. He beat Jaume Munar comfortably, then ground out a 7-6 6-7 6-3 win over Aleksandr Shevchenko in a lengthy quarterfinal. He also picked up a walkover in the second round against Tomas Martin Etcheverry, so his legs should be reasonably fresh heading into this one. The Argentine is not to be dismissed lightly. He has a solid first serve and when he finds his rhythm he can really take time away from opponents. The one thing worth noting in the head to head is that Tirante won their only previous hard court meeting, at the 2025 Cancun Challenger, in straight sets. This will be their first encounter on indoor hard courts, so that caveat is worth keeping in mind.
That said, Tabilo’s experience at this level, his ability to construct points patiently from the baseline, and the composure he has shown throughout this tournament all point in his favour. The head to head record is overwhelmingly in his corner and he has won both of their 2026 meetings. Tirante will make it competitive but I think Tabilo finds a way through, possibly after a tough opener.
Musetti leads their head to head by five wins to three, and he got the better of Fritz most recently in the Lyon final, winning 6-3 6-4 just a couple of weeks ago. That is a confident recent reference point for the Italian. His indoor hard court form this season has been genuinely excellent, compiling a 10-2 record on the surface. Beyond Lyon, he beat Alexander Zverev at the Paris Masters, which is the kind of scalp that underlines how well he has adapted his game to quicker conditions. In Stockholm he has beaten Toby Samuel and Ugo Humbert, with the Humbert match being particularly revealing. He dropped the second set, fell behind in the third, and still found a way to close it out 7-6 6-3 in just under two and a half hours. That kind of resilience matters in a semifinal.
Fritz has had a more straightforward route to this stage. He had a first round bye, beat Cameron Norrie 7-5 6-3, then received a walkover when Holger Rune pulled out of their quarterfinal with a hamstring problem. The lack of a proper match in the last round could be a factor if Musetti comes out firing, though it also means Fritz will be physically fresh. He is into his seventh semifinal of the season and his third in four weeks, so whatever the route, he keeps finding himself in these positions. He also has a personal incentive here, with one more win enough to seal another year end top ten finish.
The key statistical nudge in Fritz’s favour is that he has won two of their three previous indoor hard court meetings. His serve is a genuine weapon in these conditions, where shorter points and aggressive first strike tennis suit him. Musetti thrives when he can use variety and change the rhythm of exchanges, but on a fast indoor surface with Fritz dictating with that forehand and serve, it becomes harder to execute. I think Musetti will push him hard and there is a real chance this goes the distance, but Fritz’s indoor record in their rivalry and his overall serving advantage tip it his way.
