Summertime is in full swing in Europe, and that means one thing: the 2026 Wimbledon Championships are upon us. The intrigue at the most prestigious event in tennis could not be higher on the men’s side as No. 1 Jannik Sinner hunts for back-to-back titles at SW19. As always, we at LWOT offer our roundtable analysis and predictions on each match. Let’s dive in.
Wimbledon Day 1 Predictions
Stefanos Tsitsipas vs Hugo Gaston
Ilemona
Gaston came through qualifying with some confident tennis and has the variety to make life awkward, especially with his drop shots and angles. Even so, Tsitsipas has looked more settled in recent weeks and his bigger serve and willingness to finish points at the net should allow him to dictate most of the rallies.
Prediction: Tsitsipas in 3
Zain
At just 27 years of age, Stefanos Tsitsipas looks like a shell of the player he was a couple of years ago, now firmly out of the top 50 rankings. The Greek has always struggled at Wimbledon, even when he was at his best at other tournaments, and the baseline game of Hugo Gaston will likely test him here as well. If the Frenchman remains composed and takes his chances, he should win.
Prediction: Gaston in 5
Tope
Hugo Gaston arrives at Wimbledon on the back of three qualifying wins, but his record at the All-England Club, a solitary second-round in 2022, does little to inspire confidence. Across the net stands Stefanos Tsitsipas, a former world number three whose ranking has since tumbled to 88, his Wimbledon ceiling a round-of-16 appearance as a teenager back in 2018. Yet for all of Tsitsipas’ struggles, this matchup tilts in his favour.
Prediction: Tsitsipas in 4
Martin Damm vs Marco Trungelliti
Ilemona
Damm’s powerful serve naturally suits grass, and he has shown throughout the season that he is becoming more comfortable at ATP level. Trungelliti brings plenty of experience and arrives with confidence after an excellent year, but the quicker conditions are likely to help Damm earn enough cheap points to stay in control.
Prediction: Damm in 4
Zain
Marco Trungelliti is the more experienced player here, but grass is arguably his least preferred surface as the Argentine is a typical clay-court grinder. While that means he can have stretches of good play from the baseline, Martin Damm’s serving advantage and aggressive approach should be enough to see him through on a surface that rewards attacking tennis.
Prediction: Damm in 4
Tope
Martin Damm arrives in better shape, carries the heavier weapons and a stronger grass-court pedigree, and if his first serve lands with authority, Trungelliti’s game may struggle to absorb the pace. The Argentine is a fighter who has earned his unlikely moment in the spotlight, but this surface tends to reward power over persistence. Damm should advance and could do so with a degree of comfort if he is anywhere near his best.
Prediction: Damm in 3
Nicolas Mejia vs Adolfo Daniel Vallejo
Ilemona
Neither player has much experience in the Wimbledon main draw, making this an intriguing matchup between two competitors still looking to establish themselves. Mejia has put together the steadier results over recent months, and his ability to extend rallies while taking his chances on serve could prove decisive over five sets.
Prediction: Mejia in 4
Zain
Both of these players like to play on slower surfaces and stick to the back of the court, using their groundstrokes to cause damage. As such, this match presents an opportunity for either player to reach the second round at Wimbledon. Given his level during the qualifying rounds, I think Nicolas Mejia should have the slight edge over Adolfo Daniel Vallejo, one that can prove to be the difference.
Prediction: Mejia in 5
Tope
Adolfo Daniel Vallejo arrives at Wimbledon with question marks hanging over his grass-court credentials. The Paraguayan’s clay-court pedigree is real, with two Challenger titles from four finals in 2025, but grass is an entirely different conversation. Mejia, meanwhile, has earned his place in the main draw the hard way with three solid qualifying wins. The Colombian carries genuine momentum into this encounter, and on a surface where Vallejo has yet to prove himself, that may be the decisive edge.
Prediction: Mejia in 3
Jannik Sinner vs Miomir Kecmanovic
Ilemona
Sinner arrives at Wimbledon as the defending champion after another outstanding first half of the season, and his game has become increasingly comfortable on grass. Kecmanovic has yet to find a way to consistently trouble Sinner, whose returning and movement should give him the edge from the opening games.
Prediction: Sinner in 3
Zain
Remarkably still searching for a Major title this year, Jannik Sinner enters Wimbledon this year as not only the defending champion but the big favorite to win it again. But, while the questions regarding his physical state after what happened at the French Open will remain, and Miomir Kecmanovic is not the easiest first-round opponent, anything other than a straightforward Sinner win here will be a shock.
Prediction: Sinner in 3
Tope
Jannik Sinner skipped the grass-court warm-up swing entirely, a gamble that puts his early sharpness under scrutiny and while Kecmanovic offers a modest threat, history offers little comfort for him as Sinner leads their head-to-head 4-0, including a straight-sets win over Kecmanovic at this very stage two years ago. Expect rust in the opening games, but Sinner’s class should assert itself cleanly enough for a routine first-round passage.
Prediction: Sinner in 3
