World number 5 Alexander Zverev is through to the semi-final for the ninth time in 2018 after his 52nd win of the season, taking down the 8th seed Roberto Bautista Agut 7-5 6-3 in an hour and 45 minutes for the fourth straight win over the Spaniard. The German fired 12 aces and he kept his second serve under control in order to save five out of seven break points, stealing half of the return points to create no less than 19 break points, converting five to secure the triumph in straight sets.
Sascha had the upper hand on the court, hitting 32 winners and 36 unforced errors while Roberto had only 11 direct points and 30 errors, struggling to find the range and spraying too many errors from his backhand. Zverev earned a break in the very first game of the match but he stayed ahead for only three games, getting broken in game four when his backhand landed long.
Both players struggled on serve in the middle of the set but they stayed unbroken, reaching 5-5 before Alexander converted the fifth break point after another backhand mistake from the Spaniard, moving 6-5 ahead and closing the set with a 40-rally shot and a service winner in the game that followed.
Bautista Agut scored a break in the second game of the second set after some impressive defense, holding at 15 in the games between that one for a 3-0 lead. Still, he wasted all that in the fifth game after a terrible forehand that took all the momentum from him.
A forehand winner in the seventh game delivered another break for the German and he sealed the deal with a break at love at 5-3 for the place in the last four where he will face a qualifier Marius Copil. The 22-year-old Daniil Medvedev is through to his fifth semi-final of the season and the third in the last four tournaments after a solid 6-4 3-6 6-3 win over another youngster Stefanos Tsitsipas in an hour and 50 minutes, beating the Greek for the third time in 2018. We saw another cold handshake at the end of the match as they already have history from the previous encounters but it was an entertaining match with a lot of nice winners and attractive points, highlighted with a single break in each set.
In the end, Medvedev tamed his shots in a more efficient way, firing 21 winners and 26 unforced errors, saving three out of four break points to keep his serve safe in sets one and three. Tsitsipas claimed his maiden ATP title in Stockholm last week but he couldn't repeat that here in Basel, spraying more than 30 unforced errors and falling down after a crucial break in the eighth game of the final set.
Stefanos had a break point already in the second game but he couldn't convert it, losing a 37-shot rally and getting broken in the next game when his backhand landed long. Daniil served well in the rest of the set, clinching it in the 10th game with a service winner after 36 minutes, hoping for more of the same in the rest of the match.
Tsitsipas had the upper hand on the court in set number two, wasting two break points in game two but finding the way to break Medvedev at 4-3 after a double fault from the Russian, serving for the set in the following game.
He forced an error from his rival in the ninth game, taking the set 6-3 and grabbing the momentum before the decider where he was the favorite now. Nonetheless, Medvedev regrouped and he lost just six points in five service games, keeping the pressure on Tsitsipas and breaking him in game eight after a poor backhand from the Greek.
The Russian moved across the finish line with a service winner in the ninth game to set another clash against Roger Federer against whom he won a set two weeks ago in Shanghai. Quarter-final results:
