The numbers behind Mike De Decker’s fall - From World Grand Prix winner to fighting for darting future

Following his World Grand Prix Title in 2024, Mike De Decker has failed to return to the top of darts and experienced a slow decline in the last two years. Defending £120,000 in October, De Decker risks falling outside the top 32 for the first time since he won the title in Leicester, turning a new chapter where the Belgian is not seen as a top player. Losing 61% of his games in 2026 and struggling to qualify for every major in the last 3 months of 2026, the numbers behind this explain the sudden fall after his maiden major title win.

Throughout 2025, Mike De Decker qualified for most majors on the back of his Grand Prix win, riding the wave that saw him guaranteed prize money to keep his stay in the top 24 of darts. Now sitting World Number 24, the Belgian is only qualified for the World Championship and is below players without a tour card in the Players Championship finals race, including Tommy Morris and youngster Henry Coates. Defending £120,000 is a feat any player would be endangered by, but not qualifying for the event means the fear becomes impossible. Outside the World Grand Prix by £35,500, this money is bound to drop and this isn’t the only large sum of money dropping.

Outside the European Championship and Players Championship places, De Decker defends another £35,000 on top of this £120,000 sum, and this is explained by his stats. When qualifying for events, De Decker had a win percentage of 58%, a solid but most definitely below top level win percentage for the 30 year old. However, 2026 saw this figure drop to 39%, losing more than six of his ten matches which no matter how great the other four wins may be, will not sustain at the elite level of professional sport.

De Decker has benefited from seeded positions in many floor events yet failed to capitalize: 14 Players Championship exits and 8 European Tour exits. Furthermore, he has failed to average over 90 in 6 of those Players Championship events and 3 of the European Tour events. In the last 5 months, De Decker has averaged 90.78, which is far below tour level nevermind a player sitting inside the top 24. In the first 6 months of 2025, Mike De Decker averaged 94.50 and with a checkout percentage of 39.24%, his world ranking was completely justified.

These stats led him to the European Tour finals in Weise and his frustration at missing the Premier League in 2025 was understandable given his Grand Prix win. Yet, this doesn’t explain his stubbornness. Failing to attend the Dutch Darts Masters in 2025 as a result shows a lot of signs that explain the downfall. Danny Noppert would have felt snubbed this year, and James Wade, but they continued and didn’t have a public outcry.

On a psychological standpoint, this ego doesn’t produce performances and in the case of De Decker, has only caused a decline due to stubbornness to accept that he is in a performance dip. In an interview with Online Darts in 2025, De Decker said “At that time I thought I deserved it, but then if you look at 2025, it's a good thing that they didn't put me in”, showing a player who still believed he belonged at that level despite the evidence suggesting otherwise.

This shouldn't be a question when averaging in the low 90s and with his mindset. A clear change in his mindset can also be seen, seen when Mike De Decker exclaimed in the same interview “Hopefully I can go back to the feeling of end 2024. Then I would go into any game saying 'I will win this.' And last year I was hoping to win.". Hoping to win doesn’t produce results because De Decker would be pushing for darts to go into the treble bed, rather than trust himself for them to go into.

Now, with a 39% win percentage, a hope to win would be blinding optimism and this trust to win is a thought further away than his World Grand prix win. His game against David Munyua explained this. 2-0 up against the unknown African qualifier with little pushback is a comfortable position any player would know. Within an hour, Munyua was in London celebrating his first World Championships and put himself in the darts history books. Speaking after the match, De Decker exclaimed “There was something in me that said, 'Yeah, you're going to lose this.' And that's not a good thing to have when you're 2-0 or 2-1 up.".

That mindset is dangerous and it would have crept in on every lead Mike De Decker held in 2026, and it shows. His average is down by 4 points, his checkout percentage even more. This psychologically is the biggest illustration of how far he’s fallen.

For any player, practicing is needed to keep up the consistent level in the player’s game. Mike De Decker has admitted a problem to his attitude of practicing since his World Grand Prix win, with interviews revealing his attitude to practice is a structural distaste and failure to want to practice. Whether the Grand Prix win created a complacency that made practice feel unnecessary is impossible to say with certainty, but it explains the downfall. In an interview with Tungsten Tales in 2026, De Decker said “If I have to practice on my own, I get bored quite easily. So I try to invite some friends over to practice... because if I don't do it, then after an hour I just put them aside and stop because it is just so boring alone”. This attitude is, no doubt, the reason for his downfall. Without knowledge of his personal life, a professional sportsman whose job it is to play a sport must practice. It is not optional and De Decker now is facing the consequences of this.

He’s not going into tournaments sharp and although the Grand Prix and the back end of 2024 was successful, the rest of 2024 outside the Grand Prix win was not significantly stronger than 2025 or 2026 in terms of results. But, in 2026 the practice problem is revealing itself. In the first 5 months of 2026, De Decker played with a 92.35 average, and this dropped to 90.78 in the space of 3 months. the drop in average from 92.35 to 90.78 in three months, well beyond the equipment adjustment period, strongly suggests practice is a contributing factor Furthermore, inviting friends, not other darts professionals or strong amateurs is another problem. That isn’t practice. That is a game and it removes the mindset and the psychological stress of a game that can't be replicated when playing with friends to practice.

Doubles aren’t as important compared to a PDC match, a treble 20 to get down to 161 on 261 similar. He’s addressed this problem, but without the conviction that is needed; “I've been pushing myself to practice more going into 2026... a lot more than I did last year.". This isn't a guarantee to practice, more a pledge to practice on the back of his poor 2025. Now with his win percentage dropping 19%, this pledge clearly hasn't been fulfilled. What could go wrong has gone wrong for De Decker and his lack of practice can be scapegoated. Something else can as well.

Signed to Bulls throughout his career and playing with the same setup for eight or nine years, De Decker's switch to Mission after his Grand Prix win was the uncalculated error that set everything else in motion. Not switching his darts for 8 years since his change to Mission, a switch to a different set up is a jump that can’t be understated. New coating, new grip, new length, new tungsten. This took De Decker longer to get used to them than expected. In 2024, his BULLS set up included a natural tungsten barrel with micro ringed grooves and short stems. This can’t be criticized as it brought De Decker major success and his first PDC floor title, with it used through his whole PDC career. In 2026, De Decker is using a Gold Titanium PVD coated barrel, with dual zone square ring cuts and wide grooves, and pattern flights rather than clear red flights.

In 2024 with pure tungsten darts, the sliding between each dart produces predictable sliding deflections, meaning dart two and dart three glide down dart one and into the same bed. Yet Gold Tin PVD sliding against Gold Tin PVD, this creates a stick slip phenomena when barrels collide at high velocity, which is definitely likely with De Decker’s short stems and his powerful throw. Not just this, The shorter 2024 darts compared to a longer 2026 dart has shifted the balance point of the dart, altering the natural grip and now changing a throw built across nine years of the same darts. With all variables combining, a doubt loop has been caused and can be seen with his darts. This biomechanical analysis can be seen with his initial misses; bound to happen with any dart player and especially with a dart player who doesn’t practice as much as they are required to. After this, a micro adjustment failure is caused, and a loss of trust has been found. Now with every dart De Decker throws, there will be hesitation mid back-swing on high pressure scenarios. This explains his loss to David Munyua. Psychologically, De Decker isn’t the same player we saw in 2024 and his darts could be to blame.

With this new equipment change in 2025, he made a European tour final. A new chapter seemed to be turned, but with no knowledge about the repercussions of this, it could have been the worst thing to happen. It was a false positive, with De Decker admitting in the interview with Tungsten Tales “I was too stubborn to make a change early in the season. I made a final in Wieze and then I thought, 'Yeah, it can't be the setup.' But the whole season was with ups and downs... I knew something had to change and I think I just waited a bit too long with it.". Wieze made De Decker think his new darts were the answer, but he dismissed the evidence that it was negatively impacting his darts, and later appealed with repeated public mentioning of his Premier League Omission. Psychologically, this was damaging because all the negatives relieved itself and in due time, this premier league dismissal was admitted as correct.

Then, a Players Championship 5 semi-final. But overall, he won just £146,000 in 2025, a lower number than the amount he defended in the last 3 months of 2026. In the same interview, he dropped the line that summed up his downfall. “If you win one major, you think you can win any major, and that's how I went into tournaments. The switch to Mission didn't help at that time.". This complacency defines De DEcker and his season still hasn’;t recovered, and 2027 could be worse for him

The numbers behind De Decker's fall are damaging enough in isolation. Where they lead is more alarming. His current ranking total stands at £407,000 across two years, but 52.6% of that, £214,250, was earned in 2024. The majority of that 2024 money is spent between October and December 2026, with £120,000 of it coming from a single result: the World Grand Prix he won inLeicester. Defending champion. Forty-fourth in the qualifying standings. No where near the field. That is where De Decker stands heading into the most important event of his career since winning it. He has already missed the World Matchplay, failed to qualify for the European Championship and fallen outside the Players Championship Finals top sixty-four.

The World Championship is the only major he is guaranteed entry to, and that is not because of his 2026 form. It is because of his 2024 results buying him one more year of automatic inclusion. Without the Grand Prix win still in the window, that conversation changes too. A first or second round exit at the Grand Prix produces between £7,500 and £15,000. The net loss on that single event is approximately £105,000 to £112,500. Combined with the £35,000 he is defending across the European Championship and Players Championship Finals, events he has already failed to qualify for, the total defending exposure between October and December is approximately £192,750. His 2026 earnings so far: £46,750. The maths is straightforward and it is brutal.

If the World Grand Prix produces a first round exit, his two-year total falls to approximately £294,500. That puts him around the world thirty-sixth to fortieth. Outside the top thirty-two means losing automatic World Matchplay qualification. Outside the top sixteen means losing World Grand Prix seeding. He is already outside both of those thresholds on current form and the defending window makes it structurally worse, not better. There is one honest positive.

The Players Championship 12 quarter-final run beating Bunting, Vandenbogaerde and Ross Smith, and the 107.14 against O'Connor at European Tour Nine, show the ability has not left. The shorter shaft discovery showed comfort can return. But structure changing in August does not rescue a year that has already produced fourteen Players Championship first round exits, eight European Tour first round exits and a 39% win rate. October arrives in six weeks. £120,000 drops off in six weeks. A player who waited twelve months to fix a problem he knew about in month one has not shown the urgency that the next six weeks require.
