The 4th seed Andrey Rublev is through to the semi-final in Halle, the sixth of the season and the first since Monte Carlo. Andrey took down the experienced German Philipp Kohlschreiber 7-6, 6-2 in 81 minutes, dropping only 13 points behind the initial shot and moving over the top with a double break in the second set.
The Russian hit 29 winners and 12 unforced errors, controlling the pace and playing on a high level from start to finish to remain on the title course. The champion from ten years ago remained in touch in the opening set, fending off a break point in the sixth game with a forehand crosscourt winner to stay on the positive side.
Both players served well in the rest of the set, and Kohlschreiber built a 4-2 advantage before Rublev pulled the mini-break back. The Russian seized another mini-break at 5-4 and closed the set with a beautiful backhand slice winner in the 11th point for a massive boost.
Andrey kicked off the second set with a break thanks to a forehand down the line winner, producing one good hold after another and forging a 5-2 advantage with another break in game seven when his backhand down the line found an open court.
Serving for the victory, Rublev fired a service winner in game eight to advance into the semis and set the Nikoloz Basilashvili clash. The Georgian qualified for the main draw and defeated Lloyd Harris 6-4, 7-6 to enter the last four, getting broken once and delivering two return games that carried him through after a tight second set.
Andrey Rublev and Felix Auger-Aliassime could meet in the Halle final.
After losing the Stuttgart final to Marin Cilic, Felix Auger-Aliassime is a win away from another title match following a commanding 6-3, 6-2 victory over Marcos Giron in 58 minutes.
The Canadian fired 25 winners and just seven unforced errors, barely dropping a point on serve and keeping the pressure on the other side. Giron couldn't match that pace and lost serve thrice from as many chances offered to his rival to end his run in the quarters.
The American netted a forehand in the sixth game of the opener to fall 4-2 down before Felix closed the set with a volley winner in game nine. Auger-Aliassime broke in the second set's third game and opened a 4-1 gap to move closer to the finish line.
Serving for the victory in game eight, the youngster fired a service winner to move over the top in style and remain on the title course.
