Vaughan and Alexander Claim ITF J200 Titles in Mason Ohio; Young and Wolf Meet for M25 Tulsa Title; Shcherbinina vs Ekstrand, Johnson vs Nakashima in Irvine $15K Finals; Five Americans Advance to Finals at Four ATP and WTA Grass Tournaments

Mason Vaughan won his first ITF Junior Circuit singles titles today, with the No. 12 seed defeating 15-year-old Teodor Davidov, the No. 13 seed, 6-0, 6-4 in the ITF J200 final in Mason Ohio. The 16-year-old from Dallas did not drop a set in his five victories.

In the all-Canadian girls final, 16-year-old Avery Alexander, the No. 4 seed, defeated 18-year-old Clemence Mercier, the No. 15 seed, 6-4, 7-5 to earn her eighth, and biggest, ITF Junior Circuit singles title. Alexander had fallen out of the ITF Top 100 after breaking into it as a finalist at the ITF J300 in San Diego in March, but with this title she will move inside the Top 80 in next week's rankings.

Wild card JJ Wolf has advanced to the final of M25 in Tulsa Oklahoma, with the former Ohio State All-American hoping to begin to build some momentum after being out nearly all of 2025 with an injury.

The 27-year-old from Ohio, who reached No. 39 in the ATP ranking in February 2023, defeated top seed Andres Martin(Georgia Tech) 3-6, 6-3, 6-4 in today's semifinals. Wolf, who won his first tournament in his return from injury at an M15 in February, went 1-2 in the spring green clay ATP Challengers, then retired with an injury in the quarterfinals of the M15 in Vero Beach early last month.

Wolf will face unseeded Gavin Young(Michigan), who took out former Michigan teammate and doubles partner Andrew Fenty, the No. 5 seed, 3-6, 6-3, 7-6(4) in a three-hour and 15-minute battle. Young, 23, won an M25 in Costa Rica earlier this year.

Young was not able to earn his third pro doubles title today, with he and partner Justin Boulais(Ohio State) of Canada, seeded No. 2, falling to unseeded Jack Vance and Axel Nefve(Notre Dame, Florida) 6-4, 6-4 in the final.

Unseeded Spencer Johnson has advanced to the final of the M15 SoCal Pro Series tournament in Irvine California, with the rising senior at UCLA beating No. 2 seed Strong Kirchheimer(Northwestrn) 7-5, 6-3 in today's semifinals. Johnson, who reached the semifinals of two previous M15s in the SoCal Pro Series, including last week in Los Angeles, will play wild card Bryce Nakashima, who is playing in his first tournament since completing his junior year at Ohio State.  Nakashima defeated No. 4 seed Kenta Miyoshi(Illinois) of Japan 4-6, 6-2, 7-5 in a two-hour and 40-minute semifinal. Whoever wins Sunday will earn his first Pro Circuit singles title.

Johnson has already claimed his first pro title, winning the doubles championship today with UCLA teammate Emon van Loben Sels. The No. 4 seeds defeated the unseeded team of Sam Landau(Duke, Indiana) and Noah Zamora(UC-Irvine) 6-7(5), 6-4, 10-6. That title probably took a bit of the sting out of not being selected for the USTA's American Collegiate US Open Wild Card Playoffs this week, after they finished .06 points behind the fourth and final entry, Northwestern's Carter Pate and Greyson Casey.

Alina Shcherbinina of Russia has extended her winning streak on the SoCal Pro Series to ten, advancing to her second consecutive final with a 7-5, 6-2 win over No. 7 seed Midori Castillo Meza(Arizona) at the W15 in Irvine. The 22-year-old Shcherbinina, a doubles All-American at Oklahoma in 2024, will face No. 2 seed Monika Ekstrand, a rising sophomore at Stanford.

Ekstrand prevented a rematch of last week's Los Angeles final when she avenged her semifinal loss to Kaitlyn Carnicella(Auburn, South Carolina) there with a 6-4, 6-2 win today. Neither the 19-year-old Ekstrand, who won two W35s last year, nor Shcherbinina have lost a set this week.

The unseeded team of Australian Lily Fairclough, a rising senior at USC, and Kate Fakih, a rising junior at UCLA, won the women's doubles title, beating No. 2 seeds Castillo Meza and Brandelyn Fulgenzi(Arizona) 7-6(6), 6-4 in today's final. 

It's Fairclough's eighth pro doubles title; somewhat surprisingly, it's Fakih's first, given her National 18s doubles title and her appearance in the NCAA doubles final in 2024, both with Olivia Center.

Sunday's finals of both ATP tournaments and both WTA tournaments will feature Americans, with a US champion guaranteed at the ATP 500 in Halle Germany.

Taylor Fritz, the No. 5 seed, continued his dominance over top seed Alexander Zverev of Germany, beating the Roland Garros champion 6-7(4), 6-4, 7-5 in today's semifinals. Fritz will play unseeded Frances Tiafoe, who defeated wild card Daniel Altmaier 6-3, 6-1. It's their ninth meeting, with Fritz holding a 7-1 lead in the head-to-head.

Tommy Paul will play for his second straight title at the ATP 500 in London, although he was unable to play it in 2025 due to injury, he did win the title at Queen's Club in 2024. The No. 8 seed defeated Ugo Humbert of France 6-3, 6-3 to set up a meeting with No. 7 seed Francisco Cerundolo(South Carolina) of Argentina. Cerundolo prevented another all-US final with a 6-7(5), 6-3, 6-4 win over Brandon Nakashima.

No. 3 Jessica Pegula defeated WTA No. 1 Aryna Sabalenka of Belarus 6-4, 6-7(4), 6-0 in today's semifinal of the WTA 500 in Berlin, and will face No. 8 seed Linda Noskova of Czechia for the title Sunday. Noskova defeated Alexandra Eala of the Philippines 6-2, 6-4.

No. 3 seed Emma Navarro(Virginia) is through to the final of the WTA 250 in Nottingham England, where she will play No. 4 seed Marie Bouzkova of Czechia. Navarro defeated qualifier Viktorija Golubic of Switzerland 7-6(5), 6-2 in today's semifinals, while Bouzkova beat fellow Czech Karolina Pliskova 6-4, 6-1.
