Kazakhstan's Elena Rybakina clinched her fourth WTA title with victory in the Italian Open as Anhelina Kalinina retired with a leg injury.
Wimbledon champion Rybakina was leading 6-4 1-0 when her Ukrainian opponent, who had strapping on her left leg, retired in tears after 65 minutes.
It was Rybakina's third walkover victory of the tournament in Rome.
The win gives the 23-year-old a top-four seeding at the French Open, which starts at Roland Garros on 28 May.
The final got off to a late start as rain backed up play on centre court for most of the day.
