BASEL, Switzerland — On a tough day for seeded players in the Swiss Indoors first round, Stan Wawrinka rallied to beat 119th-ranked fellow Swiss Marco Chiudinelli 6-7 (1), 6-1, 6-4 on Tuesday.
Top-seeded Wawrinka advanced after second-seeded Milos Raonic and sixth-seeded Grigor Dimitrov both let one-set leads slip and exited early.
Wawrinka ended his own streak of four straight first-round losses in the hometown tournament of Roger Federer, whose season-ending injury ruled him out for the first time since 2005.
World No. 3 Wawrinka clinched victory with his 16th ace on his fifth match point chance against his Davis Cup teammate Chiudinelli. He next plays qualifier Donald Young of the United States.
The bottom half of the draw opened up Tuesday after Canada’s Raonic lost to Ricardas Berankis of Lithuania, a player ranked 87 places below him.
The fourth-ranked Raonic took the first set against his 91st-ranked opponent before falling to a 3-6, 6-3, 6-3 loss.
The 26-year-old Berankis now has two career wins against top 10 players, after also beating Raonic indoors in Moscow two years ago.
Dimitrov of Bulgaria let 37th-ranked Gilles Muller of Luxembourg fight back for a 6-7 (9), 6-4, 6-4 win after taking only one of his 10 break point chances against the 33-year-old left-hander.
NUREMBERG, Germany — Swedish player Johanna Larsson won her first WTA singles title in three years by beating Alison Riske of the United States 7-6 (4), 6-4 in the final of the Nuremberg Cup on Saturday.
Her only other career singles victory was on home soil at Bastad in 2015.
Having come from a set down to win matches in the quarterfinals and semifinals, Larsson rallied from a break down in the first set and won the last four points of the tiebreaker. Larsson then won the final five games to take the match and deny Riske a second career singles title.
“When I held for 4-2, I could see some signs that she was a little bit tired,” Larsson said, “and that gave me a lot of energy to fight back.”
STRASBOURG, France — Third-seeded Anastasia Pavlyuchenkova of Russia won the Strasbourg International after laboring to a 6-7 (5), 7-6 (3), 7-6 (6) win against Dominika Cibulkova of Slovakia on Saturday.
They spent 3 hours, 35 minutes on court in a grueling contest, which ended when Pavlyuchenkova sealed victory on her second serve.
Pavlyuchenkova won her first title of the year and 12th overall, beating Cibulkova for the fourth time in their 11 career meetings.
Fifth-seeded Cibulkova was bidding for her ninth career title.
Both players head to the French Open in Paris, where first-round play starts Sunday.
Cibulkova reached the semifinals at Roland Garros in 2009, while Pavlyuchenkova reached her only quarterfinal there in 2013.
