2026 World Tennis Tour Junior Finals: meet the boys
The countdown to the 2026 World Tennis Tour Junior Finals – the junior equivalent of the ATP and WTA Finals – is on.
Play starts on Wednesday 21 October and there will be livestreams available each day on our junior tennis livestreaming platform. Those who have qualified for the Finals will begin to arrive in Chengdu over the weekend, but who are they?
Currently ranked No. 2 in the World Tennis Tour boys’ rankings, Mackenzie has reached at least the quarter-finals in all but one junior event this season. The 18-year-old enjoyed an exceptional clay-court campaign ahead of Roland Garros, winning singles titles at both J500 Offenbach and J500 Milan. J500s are effectively a rung below Junior Grand Slams in terms of ranking points on offer so these were big wins. He proceeded to reach the last eight at the Roland Garros Junior Championships, as he did at the Australian Open Junior Championships in January. His best Junior Grand Slam singles result this season was reaching the semis at the US Open Junior Championships, although he did win the Roland Garros boys’ doubles title alongside Vincent Reisach. The teenager has continued to gain experience within the pro game and reached the final at the Bonn Challenger in August.
Another to have enjoyed a thoroughly consistent season. Behrmann has won four World Tennis Tour Juniors singles titles in total, with the most impressive coming at J500 Cairo in April. The others were won at J300 Vrsar, J300 Oberpullendorf and J200 Gurugram. At the Junior Grand Slams, Behrmann advanced to the semi-finals at the US Open Junior Championships and the last eight at the Roland Garros Junior Championships. Behrmann is one of many players around the world to have received financial assistance through the World Tennis-operated Grand Slam Player Development Programme. The support came in the form a Grand Slam Player Grant. This support is financed by the four Grand Slams with World Tennis modelling determining which players are selected for support.
The 18-year-old achieved a major milestone in his career in April as he lifted silverware at M15 Orlando to claim his maiden pro singles title on the World Tennis Tour. This is the player pathway in operation: success at junior level leading to exposure to professional events with the intention of one day advancing to the ATP and WTA Tours. Hance has also won a couple of doubles titles on the World Tennis Tour this season – at M15 Orlando and M25 Vic – which follow his doubles triumph at the 2025 US Open Junior Championships alongside Jack Kennedy. He won the doubles at M25 Vic with Kennedy also, while the M15 Orlando title was won with Jordan Lee. Hance is yet to win a junior title in 2026, although did reach the final at the Australian Open Junior Championships and semis at the Roland Garros Junior Championships.
By far and away the biggest moment of Lee’s season came at Wimbledon as he conquered all before him at the Junior Championships to claim the maiden Junior Grand Slam of his career. At 16 years and 69 days, Lee was the youngest player to begin the Wimbledon boys’ singles draw – after navigating qualifying – while he was the youngest player to win a Junior Grand Slam title at Wimbledon since Shintaro Mochizuki in 2019. The week was also noteworthy as lookalike comparisons between Lee and football sensation Lamine Yamal resurfaced. Lee also reached the quarter-finals at the US Open Junior Championships in September, while he won J200 Sumter in May. He has continued to gain exposure to the professional game on the World Tennis Tour and won the doubles at M15 Orlando alongside Hance in April.
Sesko is another player to have won the first professional title of their career in 2026, and he did so at M15 Wels on the World Tennis Tour in August. The 18-year-old reached another final and a semi-final on the World Tennis Tour this year to underline his undoubted quality and future potential. Another crowning moment came at the beginning of the year as Sesko became the first Slovenian boy to win a Junior Grand Slam singles title after conquering all before him at the Australian Open Junior Championships. He also became the first member of the World Tennis-operated Grand Slam Player Development Programme Touring Team to win a Junior Grand Slam singles title since Ricardas Berankis in 2007. He proceeded to win the Wimbledon boys’ doubles title alongside Brazil’s Luis Guto Miguel in July.
As with some of the other boys who will be on show at the World Tennis Tour Junior Finals in Chengdu, Kisimov has also won the maiden professional title of his career in 2026 – at M15 Kursumlijska Banja in August. Such a milestone is not to be underestimated as it proves to a player they can mix it at that level and proves all the hard work and dedication is worth it. At junior level, the 18-year-old triumphed at J300 Cairo, while he reached the final at J500 Offenbach, were he lost to Mackenzie, and the semi-finals at J300 Plovdiv. His best showing in singles at a Junior Grand Slam was reaching the quarter-finals at Wimbledon in July. He did, however, win the Australian Open boys’ doubles alongside South Africa’s Conor Doig in January.
Reisach broke the Top 10 of the World Tennis Tour boys’ rankings in September which followed a solid few weeks that saw the 17-year-old reach the semi-finals at the Junior Championships, Wimbledon and then at J300 College Park. Having only made his Junior Grand Slam debut at Roland Garros earlier in the year, reaching the last four at Wimbledon was by far his best Slam performance in singles. In doubles, the won the boy’s doubles title at Roland Garros alongside Mackenzie in stunning fashion – what an introduction to Grand Slam life.
Yannik Alvarez (PUR)
Alvarez is the first Puerto Rican player to qualify for the World Tennis Tour Junior Finals. The 18-year-old currently finds himself on the cusp of the Top 10 of the World Tennis Tour boys’ rankings following a season which has seen him win three singles finals – at J500 Gaspar, J300 Asuncion and J300 Santa Croce Sull’Arno. Also in 2026, the teenager made his professional debut on the World Tennis Tour, reaching the semi-finals at M15 Boca Raton in April before making the quarters at M15 Orlando the week later. At M15 Orlando, he won the doubles title after joining forces with Ryan Cozad. Alvarez also continued to represent his nation in Davis Cup as Puerto Rico earned promotion to next year’s World Group II Play-offs.
Mathys Domenc (FRA)
Domenc is the boys' alternate at the World Tennis Tour Junior Finals, which means he is not scheduled to play competitive matches but will practice with some of the best juniors in the world and be a part of all off-court activities. However, should any player suffer injury, Domenc will assume their position in the tournament. Domenc has won two World Tennis Tour Juniors titles in 2026 – at J300 San Jose and J300 Lima – while also recording his best Junior Grand Slam result by reaching the third round at Roland Garros. The 17-year-old has also continued his development by competing extensively on the men’s World Tennis Tour this season.
