World number five Ons Jabeur claimed her first title of the season with victory over Belinda Bencic at the Charleston Open.
Tunisia's Jabeur, runner-up at Wimbledon and the US Open in 2022, beat the Swiss 7-6 (8-6) 6-4.
Defending champion Bencic played two matches on Sunday, completing a rain-interrupted semi-final against Jessica Pegula before facing Jabeur.
It is Jabeur's fourth WTA title and second on clay.
Jabeur has had a difficult start to the season and struggled with injury following her second-round Australian Open exit in January.
However, she fought back from a break down in the first set against Bencic before holding her nerve in the second to secure the title.
