Stef Kosters, a Dutch darts sensation, has rapidly ascended the competitive darts ladder, transforming from a local pub player to a formidable contender on the PDC circuit in just five seasons. After an impressive showing at Q-School and the Challenge Tour, he’s now backed by JJ Darts Management. Kosters is boldly pursuing his ultimate goal: securing a coveted PDC Tour Card and realizing his dream of competing in a Darts World Championship.
From Pub Newbie to Pro Contender: A Rapid Rise
Unexpected Beginnings
Stef Kosters’ journey in competitive darts is nothing short of remarkable. Hailing from Enter, Netherlands, he’s only in his fifth season, yet his progress has been exponential. He recalls his very first competitive match at ‘t Zumpke café, a far cry from the professional stages he now graces. Initially, he couldn’t have imagined competing on the PDC Tour just four and a half years later.
“Absolutely not. When I heard I was going straight into the Eredivisie (Dutch Premier League), I wondered if I could even handle that level,” he recounts. “In my first match, I literally had to ask what the game format was. But then I won my singles match in the second game, and that immediately helped me overcome a mental hurdle.”
Joining the Elite: Dutch Titans
For four seasons, Kosters maintained his position in the DVO Eredivisie with his team, Royal Flush. He identifies a clear turning point in his personal skill level during this period. “Two years ago, I started a bit slower, but then my game really took off,” he remembers. His exceptional form didn’t go unnoticed. The reigning champions, Dutch Titans – a team featuring Tour Card holder Dennie Olde Kalter – approached him.
“Robin Smees told me I was doing well and that they were looking for reinforcements. It’s tough to leave your team and friends, but ultimately, I chose for performance and ambition.”
Stepping onto the PDC Stage
The Development Tour Experience
Stef’s ambition led him to the PDC Development Tour, the youth circuit, where he was eligible for one final year due to his age. “Once I expressed my desire to play the Development Tour, the owner of ‘t Zumpke immediately offered to sponsor me. With some sponsorship money coming in, it became an attractive option,” he explains.
- Self-funding and Performance: “Thanks to sponsorship and some prize money, I almost broke even in that first season, which kept it enjoyable.”
- Proving His Level: “It became clear there that I could handle the level. I aimed to reach the Youth World Championship, and I did.”
- Facing Future Stars: “There you see players like Gian van Veen, Luke Littler, and Beau Greaves. I was in a group with Adam Gawlas – that was definitely a bucket list item checked off. And that makes you want to go further.”
Q-School Breakthrough: A Fortunate Turn
After one season, Kosters aged out of the Development Tour. However, this opened a new door. “Because of that, I went to Q-School. If I’d had another year on the Development Tour, I probably wouldn’t have gone,” he admits. “But I wanted to stay active and continue to measure myself against other players. I thought the step was too big, but by the end of last year, I noticed my level really soaring. Maybe I would have gone anyway, but in October, I did it purely because I couldn’t play the Development Tour anymore. A blessing in disguise, yes.”
At Q-School, Kosters performed admirably, reaching the Final Stage in Kalkar. “That was the goal, but I wasn’t sure how realistic it was. Danny Jansen said it was quite realistic, also because you only need one or two good runs.”
His journey to the Final Stage was hard-fought:
- Day 1: Lost early, but kept spirits up with teammate Arjan Konterman’s singing.
- Day 2: Made a strong run, eventually losing to a formidable Jeffrey Sparidaans who averaged over 100. “I still had darts to make it 4-4, which shows my resilience.”
- Day 3: Secured the necessary wins easily, including two 5-0 victories, to advance.
In his first Final Stage match, Kosters caused a significant upset by defeating the German Daniel Klose, a former Tour Card holder. “You see that draw, and you know Klose is a good dart player. But in a best of 11, anything can happen. He had a higher average, but I hit all my doubles at the right moments. I punished everything.”
Facing Darts Legends
While a Tour Card eluded him this time, Kosters faced a notable opponent on the final day: José de Sousa, a former Premier League player and Grand Slam of Darts winner. “He’s one of the names you really want to play against. And you’re not necessarily without a chance against him.” Indeed, Kosters had four match darts against the darting legend. “I really thought I was going to win at one point, but then I started overthinking on those four match darts. That happens to me often, and I need to overcome it. It was tough, but these are matches you’re proud of afterward.”
Professional Support: JJ Darts Management
The Partnership Explained
Kosters’ strong performances caught the eye of Jelmer Cuppers, who had just founded JJ Darts Management. “Jelmer approached me at Q-School,” Kosters explains. “Eventually, he said he was starting a darts management company with a partner, and I received a proposal. We talked, and two days later, I visited them. They told me they wanted to help me navigate the Challenge Tour.”
“They are guys from the east of the Netherlands, which really appealed to me,” he continues. “I appreciated their recognition, and I was very keen to play the Challenge Tour. We had to act fast; I signed with them on Tuesday, and I had to register for the first Challenge Tours on Wednesday.”
JJ Darts Management handles all the logistics for Stef, including:
- Flight tickets
- Hotel bookings
- Tournament registrations
“Of course, there are reciprocal agreements, but ultimately, they strengthen me because they take away all my worries. It’s an honor that I’m the first player they’ve put their trust in.”
Conquering the Challenge Tour
Proving His Mettle
With his new management, Stef took extra days off and traveled to Milton Keynes for the Challenge Tour. “On the Challenge Tour, you are constantly tested. The level of play there is truly bizarre.” Yet, Kosters held his own remarkably well.
- In the first tournament, he defeated Liam Maendl-Lawrance and Aden Kirk, narrowly losing to Danny Lauby.
- He also beat Adam Smith-Neale that weekend.
- At Challenge Tour 05, he was even the best Dutch player.
After that first weekend in Milton Keynes, he stood 52nd in the ranking. “There, I realized that I can win against players who average well over 90 against me.”
The PDC Tournament Environment
Kosters is highly impressed with the conditions at PDC tournaments. “At Q-School, the hall seems custom-made for darts,” he says. “First, there’s a seating area, and behind it, all the boards are set up. I haven’t experienced a better and quieter place to throw than Q-School.”
He notes a slight difference with the Challenge Tour: “There, the tables are in the middle, so you might hear a chair scrape occasionally. But overall, it’s also well organized. The Development Tour, Challenge Tour, and Q-School are genuine darts venues designed for the sport. PDC events are often held in these same locations, as Pro Tours are also played there.”
Future Aspirations: Tour Card and World Championship Dreams
Dutch Open and Beyond
Since Kosters doesn’t yet hold a Tour Card, he’s eligible to participate in events like the upcoming Dutch Open. His goal there? “I have a reasonable draw, including Vincent Kamphuis and Pim van Bijnen. I wouldn’t say I’m the favorite, but I definitely have a chance to make it to Sunday. Secretly, I want to go further than the last 128, and very secretly, I dream of the podium, but there are genuinely many excellent dart players competing. Let’s start by making it to Sunday.”
The Ultimate Goal
Kosters plans to play in some WDF tournaments but primarily focuses on the PDC Challenge Tour. However, this doesn’t mean he finds tournaments like Lakeside uninteresting. “Playing a World Championship someday is a goal. It’s clear which World Championship is most appealing (the PDC World Championship), but Lakeside (WDF) is certainly also a possibility. There are enough chances to qualify for Lakeside, so that’s also a dream. But the ultimate goal remains a Tour Card.”
