Alejandro Tabilo kept his run alive at ATP Stockholm on Friday, beating sixth seed Alex Michelsen 7-5, 7-6 to reach his first indoor hard-court semifinal. He saved six of the seven break points he faced, a sharp answer on a surface that has not usually brought out his best game.
That is why his name is suddenly moving through the draw now. Tabilo had already worked past Lorenzo Sonego in a three-set match this week, and the win over Michelsen pushed him into a semifinal against Thiago Agustin Tirante, who also comes in with momentum after straight-sets wins over Jaume Munar and Aleksandr Shevchenko, 7-6, 6-7, 6-3.
The matchup carries its own wrinkle. Tabilo leads Tirante 4-1 overall, but the Argentine won their only previous hard-court meeting at the 2025 Cancun Challenger in straight sets. Since that loss, Tabilo has taken their next three meetings, which makes the surface and the setting matter even more than the head-to-head record alone.
His path in Stockholm has also been tighter than the numbers might suggest. Tabilo reached this stage on indoor hard courts for the first time, yet his recent results have come with more resistance than comfort, and his six-of-seven save rate against Michelsen showed how much he had to absorb before finding his way through. Tirante, by contrast, benefited from a walkover against Tomas Martin Etcheverry in the second round, which gave him more time to recover before this run of matches than Tabilo had on the way to the semifinal.
What happens next is straightforward: Tabilo and Tirante will play for a place in the final, and the result will tell whether Tabilo’s surge on an indoor court is a real adjustment or just a week of narrow escapes. Either way, Stockholm has already given him a stage that matches the size of the moment.
