The top seed Dominic Thiem is through to the seventh semi-final of the season, defeating former Beijing champion Andy Murray 6-2, 7-6 in an hour and 54 minutes. It was their first match since Barcelona 2017 and the second straight victory for the Austrian who faced only two break points in the entire clash, mounting the pressure on Andy who gave his best to stay in touch, performing on a high level and heading to Shanghai with evident progress.
Dominic had 35 winners and 16 unforced errors while Andy counted to 29 winners and 22 mistakes, following Thiem's pace in the second set before laying down his weapons in the tie break. The Austrian made the best possible start, converting the fourth break chance with a volley winner in the first game to gain the momentum, holding at love in the next game with a service winner to confirm the advantage and settle into a beautiful rhythm.
Andy fended off a couple of break points in the third game to avoid an even more significant deficit, squandering a break opportunity in game four and suffering another break at 2-4 when his forehand finished in the net. Dominic converted the fifth set point in the eighth game for a 6-2 lead after 50 minutes, having to work hard to break Andy's resistance.
Carried by this momentum, Thiem grabbed another break at the beginning of the second set following a lucky net cord winner, serving well and moving 5-3 in front with an ace in game eight that propelled him closer to the finish line.
Serving for the victory, Thiem hit three double faults at 5-4 to get broken in the worst possible moment, allowing Murray to prolong the set and reach a tie break that the younger player won 7-3 to move over the top, finishing the encounter with a forehand winner and setting the semi-final clash with Karen Khachanov.
