World number 10 Daria Kasatkina beat Australia's Daria Saville 6-4, 6-4 on Saturday to win a WTA title at Granby, Canada, in a US Open tuneup tournament.
Kasatkina captured her sixth career WTA crown after claiming another hardcourt title earlier this month at San Jose.
World number 73 Saville was in her first WTA final since Hong Kong in October 2017 and her fifth in all. Saville's only WTA title came at another event the week before the US Open, in 2017 at New Haven.
Kasatkina, 25, is from Russia but cannot represent her homeland under rules imposed by the tour following the Russian invasion of Ukraine.
The 28-year-old Russian-born Saville is having a comeback season following Achilles tendon surgery. She fell to 0-3 against Kasatkina in their first meeting since 2017.
Kasatkina, the US Open 10th seed, will face Britain's 98th-ranked Harriet Dart in her first match on the New York hardcourts.
Mannarino wins Winston-Salem title
Winston-Salem: France's Adrian Mannarino won his second career ATP title and first since 2019 on Saturday, defeating Serbia's Laslo Djere 7-6 (7/1), 6-4 to capture the Winston-Salem Open.
The 34-year-old lefthander had lost nine of his 10 prior ATP finals, dropping three in a row since capturing his first tour title in 2019 on Rosmalen grass.
World number 65 Mannarino, who saved four match points in a first-round triumph, won 83% of his first-serve points to hoist the trophy in his first ATP final since losing the Astana Open final to Australian John Millman in November 2020.
Samsonova beats Sasnovich
Washington: Liudmila Samsonova stretched her WTA win streak to 10 matches on Saturday by defeating Aliaksandra Sasnovich to capture the Tennis in the Land title ahead of next week's US Open.
World number 45 Samsonova downed 36th-ranked Sasnovich 6-1, 6-3 in 72 minutes to make the Cleveland crown her third in as many WTA finals appearances.
"I was feeling so good here," said Samsonova after extending her career-best win streak.
Samsonova, who didn't drop a set in her championship run, also captured last year's German Open title and three weeks ago took the Washington Open trophy.
