- Andy Murray back to winning ways at Aix-en-Provence
The world No 2, Carlos Alcaraz, produced a second-set fightback to defeat Karen Khachanov and secure his place in the semi-finals of the Madrid Open. Alcaraz, the defending champion, is bidding for successive ATP Tour titles after winning in Barcelona last week.
The 19-year-old Spaniard took the opening set with a single break in the seventh game. Alcaraz, the top seed, rallied from 5-2 down in the second set to reel off the next five games and complete a 6-4, 7-5 win.
