Wimbledon Dark Horses 2026

Both the men’s and women’s events at the 2026 Wimbledon Championships sit in the same spot: a clear favorite up top, then a pile of questions beneath. On grass – the shortest, most volatile swing of the year – that’s the perfect breeding ground for Wimbledon dark horses.

The lawns hand big servers and flat hitters a weapon that’s hard to counter, and with so little time to find form, seeds tumble early most years. If you’re like me and fancy a bit of chaos in your tennis, this is the draw to dig into.

Read on for my five 2026 Wimbledon dark horses in each singles event with the game to make a deep run at SW19.

There’s no getting around it – Jannik Sinner is the heavy favorite to defend his title, and I tipped him to do exactly that in my prediction piece. But the field behind him is thin and unproven on grass, and the surface makes this anyone’s game.

That’s exactly where a dark horse can do damage. Last year alone, both Alexander Zverev and Daniil Medvedev went out in the first round at SW19 – proof of how fast the form book gets thrown out the window on these tennis courts. These are the five who could surprise.

If you’re hunting a grass dark horse at good odds but with a resume to inspire confidence, start with Berrettini. The Italian is a former Wimbledon finalist, beaten only by Novak Djokovic in the 2021 title match, and a Queen’s champion to boot. His game might be the best-suited to the surface of anyone on this list.

It’s all built around that huge, flat forehand and a hammer of a serve – two shots that stay low and skid through on grass. Add a slice that shields his backhand and lets him move forward, and you’ve got a player who turns weaknesses on slower surfaces into strengths on the lawn.

His numbers say the same: a 42-12 career grass record at a 78% clip, the best on this list bar none. When he’s right, he’s an elite grass tennis server – the type who holds for a fortnight and needs just one break a set to win matches.

Berrettini’s level is still there when his body allows, too. He reached the quarter-finals at Roland-Garros this year before an injury forced him out mid-match – and that was on clay, not his best surface. Move him to grass, where the serve-forehand combination does maximum damage, and his ceiling climbs.

The catch, as ever with Berrettini, is fitness. Injuries have wrecked chunks of recent seasons, and he managed just one grass match last year. He’s confirmed he’s back training and targeting the swing, though, and a healthy Berrettini is a nightmare draw for anyone.

At around 35.00, a fit former finalist is a serious dark horse shout.

If you want a pure high-ceiling pick, Mensik is your man. Heading into the grass season the young Czech sat at 23-10 for the year, and he already owns a scalp few can brag about – he’s one of only two men to beat Sinner in 2026.

He’s not all projection, either. Mensik already has a Masters 1000 title to his name, won in Miami last year, where he beat Djokovic in the final on the back of that enormous serve. A delivery that wins big titles on hard courts only gets more dangerous when the grass speeds it up.

The wider case for Mensik is simple. His serve is the single most valuable weapon on this surface, and his is elite – free points, short holds, no rhythm for the returner. He’s still green on grass (no pun intended), with a third round his best at SW19 and a thin record to date, so this is a projection more than a proven track record.

But that’s the dark-horse game. That serve alone keeps him in every match, and on a fast court it can carry a young player a long way before the draw catches up with him.

He’s a few good weeks from being a seed. Catch him on a hot run and Mensik is exactly the kind of name that blows a quarter wide open. Around 35.00 with the sports bookies.

Musetti is the most stylish dark horse in this field, and on his day one of the most dangerous on grass.

Wind back two years and the Italian was among the best lawn players going – a Stuttgart semi, a Queen’s final, then a run to the Wimbledon semi-finals. His movement on the natural surfaces is a joy to watch, and that one-handed backhand skids on the slick grass in a way it simply can’t on slower courts. His overall grass record sits at a tidy 18-11 (62%).

His issue is fitness and form. He was limited to a single grass match last year through injury, and came into the grass season at 13-7 after another interrupted spring. But the flashes are still there: Musetti was two sets up on Djokovic at the Australian Open before his body gave way.

That’s the real argument. A player who’d normally be seeded is landing at a long price purely because the market is pricing his injury cloud, not talent. If his body holds for a fortnight, Musetti’s grass ceiling is higher than almost anyone outside the favorites.

All signs point to him competing this swing. At around 75.00, the value’s there for an each-way punt.

Lehecka is the sleeper of this list – and the one I’d least want to draw if I were a top seed.

The Czech put together the best grass return of any of these names last year, going 7-3 on the surface in 2025, and he came into the grass swing at 17-10 for the season. A top-20 player on his day, he’s got more upside than his price implies.

His grass case is straightforward. Lehecka’s ball-striking is flat and heavy, he takes time away early, and the low bounce rewards exactly that – there’s no wind-up for opponents to read. Back it with a serve that holds up under pressure and you’ve got a dangerous player.

A round-of-16 showing is already on his SW19 record, and he’s reached a Grand Slam quarter-final on hard courts, so the deep end of a major isn’t alien to him.

The reason he’s not considered a favorite is his resume. He’s never gone truly deep at a major, and he can run hot and cold. But the raw materials are all there, and he’s got recent grass form better than most of the seeds above him. At around 75.00, Lehecka is the sharpest dark horse pick at Wimbledon this year.

Cobolli is the in-form name here, fresh off the run of his life. He took Zverev to five sets in the Roland-Garros final – his maiden Grand Slam final – and came into the grass season at 23-13 for the year.

It’s easy to forget he’s no stranger to grass, either. Last year he made the quarter-finals at both Halle and Wimbledon, so this isn’t a clay specialist parachuting onto a foreign surface – there’s a SW19 quarter-final on his CV at just 24. His natural speed and clean ball-striking already translate well to the lawns, even off a slim 9-7 grass record.

His form behind the Paris run backs it up. This season he’s lifted an ATP 500 title in Acapulco and gone deep in Munich and Madrid, beating the likes of Frances Tiafoe and Zverev along the way. Big names don’t faze Cobolli.

The caveat is the obvious one: backing up a deep Slam run a few weeks later, on a different surface, is a tall order, and the legs may be heavy.

But confidence is fuel, and Cobolli has a tank full of it. Everyone can see he’s on the verge of a breakthrough, and at a generous 100.00, the leap from dark horse to contender is well worth a small punt.

The women’s draw is wider open still. Aryna Sabalenka heads the market but has never been past the Wimbledon semis, Iga Swiatek arrives off a light grass build-up, and the chasing pack is a muddle of form and fitness questions.

Grass has thrown up surprise runs on the women’s side for years now, and there’s no reason to think 2026 is any different – an unseeded or unfancied name reaching the second week is nearer the rule than the exception on these lawns. These are the five Wimbledon dark horses who could seize the opening.

Of everyone here, Bencic has the cleanest mix of grass pedigree and current form, which makes her the shortest-priced of the women’s bunch.

The Swiss owns a 54-25 (68%) career grass record and a Wimbledon semi-final, so the surface has long suited her.

Her comeback is exciting: back competing after time away from the tour, she rebuilt at pace and came into the grass season at 21-6, with wins over Swiatek, Anisimova and Shnaider – three of the world’s best, not flattering-draw filler. She also went 5-2 on grass last year on that return, so her surface form has already held up.

Bencic’s game plays out beautifully on grass. She takes the ball early off both wings, moves cleanly, and doesn’t gift away free points – precision that matters as much as power on a fast court.

There’s little to dislike here beyond the depth of the field above her. If this comeback keeps building, a deep Wimbledon run is well within range. At around 35.00, she’s most solid pick on this list.

Vekic is proof that grass brings the best out of players the rankings overlook. The Croatian made the Wimbledon semi-finals in 2024, the run of her career, and owns a 57-38 record on the surface.

That 60% rate comes across nearly 100 tour-level grass matches, so this is craft built over years rather than a fluke fortnight. Her game is built for quick courts – a big serve, flat groundstrokes, and the kind of first-strike power that’s rewarded when the ball stays low. When she’s dialled in, she can trouble anyone over best-of-five.

The caveats are real. She came into the grass season at 12-11 for the year, the form has been patchy, and her 2025 grass swing was a disappointing 2-4. This is a player who needs momentum and a kind draw to get rolling.

But her pedigree is undeniable, and a semi-finalist from two years ago at this price is the sort of each-way value dark horse hunting is all about. Around 40.00 with most tennis books.

You can’t write a grass dark horse list without the most fearless ball-striker in the game.

Ostapenko announced herself by winning Roland-Garros as an unseeded 20-year-old, and that hit-through-anything style has never left her. Grass suits it better than clay ever did – the points are shorter, the bounce is lower, and there’s no time for opponents to dig her flat missiles out.

Her 68% career grass rate and a Wimbledon semi-final are the proof on the surface.

She owns a perfect 6-0 head-to-head against Swiatek – nobody else with three or more meetings holds a clean record against the Pole – and she’s beaten both Sabalenka and Gauff. When she connects, the very best in the world can’t live with the pace.

The flip side is her error count, which is why she came into the grass season at 16-13 rather than 26-3. She’s the definition of high-variance: 40 winners one match, 40 errors the next. Or both in the same match.

But variance is exactly what you want from a dark horse. Hand her a soft opening week and a hot start, and Ostapenko can tear through a half of the draw – just as she’s done before. At around 75.00, she’s a genuine outsider with the ceiling to justify a small punt.

Like Vekic, Paolini is a recent Wimbledon success story trading at a dark horse price. And her pedigree runs deeper than one good fortnight: the Italian reached back-to-back Grand Slam finals in 2024, at Roland-Garros and then Wimbledon, climbing into the world’s top five on the back of it. That’s elite-level form, not a one-off.

She’s a compact, relentless mover who takes the ball early and competes hard on every point – a style that works on grass better than her career numbers suggest.

To be fair, she hasn’t kicked on from that 2024 peak. Her grass record sits at 14-14 (50%), she went 3-3 on the surface last year, and she came into the grass season at 12-11 for the campaign. Consistency has been an issue.

But a major finalist’s nerve doesn’t evaporate in 18 months, and in a wide-open draw it only takes a hot fortnight to rekindle it. At around 75.00, a former Wimbledon finalist is too big to ignore for a small play.

Here’s my real wildcard: the woman who won this title just two years ago.

Krejcikova took the 2024 Wimbledon crown somewhat out of nowhere, beating Paolini in the final, and she’s a two-time Grand Slam champion all told – she also won Roland-Garros back in 2021. Her big-stage nerve is proven beyond doubt.

Her game is built for the surface, too. She’s a crafty all-courter with a biting slice, soft hands and the variety to unsettle the big hitters – and that variety bites harder on a low, skiddy court than it does on a slow one, where rhythm hitters get comfortable.

She read the lawns beautifully on that title run, mixing slice and touch to take the pace off the bigger ball-strikers. Outside it she’s no mug on grass either, at 25-13 (66%) for her career.

The catch is Krejcikova’s form and fitness. She came into the grass season at just 9-6 and has spent long stretches sidelined, so this is a leap of faith on a player well short of her best.

But champions know how to win where they’ve done it before. If she clicks into gear and the body holds, that slice-and-dice game can frustrate a draw full of power players all over again. At around 75.00, I fancy a small bet.

At the 2026 Wimbledon, both the men’s and women’s tournaments are wide open, and the Wimbledon dark horses could cause some major upsets.

Berrettini, Mensik, Musetti, Bencic, and Ostapenko all have what it takes to go deep in the tournament. For bettors looking to place successful bets, it’s worth checking out the best bookmakers, where competitive odds and a wide range of markets are available.
