Third-seeded Samantha Stosur rallied to beat Kristina Mladenovic 3-6, 6-2, 6-3 in the final of the Strasbourg International in France on Saturday, claiming her first title of the year.
The 26th-ranked Stosur, a former French Open runner-up, is returning to form after reuniting last month with former coach David Taylor.
Before Strasbourg, where she won a seventh career title, Stosur had won only eight matches in 2015.
The Australian dropped her serve twice in the opening set but was at her defensive best in the following sets, saving all five break points she faced.
Dominic Thiem held his nerves to win his first ATP tour title as he completed a tight 6-7 (8), 7-5, 7-6 (2) victory over fourth-seeded Leonardo Mayer in the final of the Open de Nice.
The 21-year-old Thiem, who defeated second-seeded John Isner in the semifinals, hit seven aces and fended off all six break points to come out on top of a nearly-three hour match at the French Open warmup tournament.
It was Thiem's second tour final after losing to David Goffin last year in Kitzbuhel.
Thomaz Bellucci of Brazil won the revived Geneva Open title, beating sixth-seeded Joao Sousa of Portugal 7-6 (4), 6-4.
The 27-year-old Bellucci's fourth career ATP title was his third in Switzerland. He also won on clay at the Swiss Open in Gstaad in 2009 and 2012.
Bellucci, a 60th-ranked left-hander, wasted three set points at 5-4 in the first before winning the tiebreaker.
He trailed by a service break in the second then reeled off four straight games to complete the victory.
Karin Knapp defeated fellow Italian Roberta Vinci 7-6 (5), 4-6, 6-1 to win the Nuremberg Cup final in Germany.
The sixth-seeded Knapp forced 17 break points and converted seven — three of those in the final set — to beat her fourth-seeded compatriot in 2 hours, 6 minutes.
Vinci had a walkover to the final of the clay-court tournament after the second-seeded Angelique Kerber pulled out of their semifinal with back problems.
