Carlos Alcaraz won the Cincinnati Open title in a little more than 20 minutes on Monday after top-ranked Jannik Sinner was forced to retire because of illness during the first set. Meeting in the final for the fourth time this year and first since Wimbledon, Sinner fell behind 5-0 in the first set with nine unforced errors. Sinner, who turned 24 on Saturday, was on 12-match winning streak and had won 26 straight matches on hard courts.
