Deegan Crowned 2025 250SX West Champion in Denver
Monster Energy Yamaha Star Racing’s Haiden Deegan scores third win of the season to secure the title a weekend early / May 5, 2025 /

Monster Energy Yamaha Star Racing’s Haiden Deegan secured the 250SX West Championship with a dramatic victory at the penultimate round of Monster Energy AMA Supercross in Denver, Colorado. The milestone victory at Empower Field at Mile High marked the 19-year-old’s fourth professional title in three years and his first 250SX Championship. Rookie sensation Cole Davies was on track for his third consecutive victory but ultimately crossed the line fifth after coming together with his hard-charging teammate in the final laps. Michael Mosiman also battled for the podium, but finished seventh after a crash late in the race. Christian Craig overcame early challenges and continued to make progress with an 11th-place finish in the 450SX Main Event.
After topping the first practice session and qualifying second, Deegan made a statement in the first race of the evening, leading every lap to take his fifth heat-race win of the season by nearly four seconds. In the main event, the Californian started third and before the halfway mark, passed Mosiman to claim the runner-up position. As the clock wound down, he closed the gap to Davies and claimed the lead with two laps to go. Deegan rode on to take the win, securing his fourth professional title in three years, and his first championship in 250SX, with three wins and a total of eight podium finishes.
Davies continued to impress in his rookie season, qualifying fifth and grabbing the holeshot in his heat race. He led every lap en route to his third heat race win of the season, heading a YZ250F sweep of the top four positions and earning the number one gate pick for the main event. The 17-year-old New Zealander grabbed another holeshot in the main event and led the field for the majority of the race. As the clock wound down, lapped traffic tightened the gap, and with two laps to go, he and his hard-charging teammate Deegan came together. Davies rejoined as quickly as he could and crossed the line fifth, maintaining his position in the runner-up spot in the championship.
Mosiman also showed strength in Denver. After qualifying ninth, he got a great start to his heat race in second and kept his teammate in sight, crossing the line in the runner-up spot and under a second behind Davies. In the main event, Mosiman once again slotted into second and maintained a strong pace in the middle of a Monster Energy Yamaha Star Racing lockout of the top three positions. Before the halfway point, he was passed by Deegan and then lost time in traffic, relinquishing the gap he had built on fourth. With around five laps remaining, Mosiman came together with another rider and went down, but rejoined the race to finish seventh.
On the 450 side of the tent, Craig continued to make progress and qualified 11th. After getting caught in a first-turn pileup in his heat race, the Californian put his head down and made an impressive charge through the pack to finish sixth. In the main event, he was 10th on the opening lap and was maintaining a top-10 result, but went off track after a mistake in the slick conditions. In 12th, Craig continued to push and crossed the line 11th.
The Monster Energy Yamaha Star Racing team heads to Salt Lake City, Utah, for another 250SX East-West Showdown at the Monster Energy AMA Supercross season finale and Round 17 of the SuperMotocross World Championship at Rice-Eccles Stadium on May 10.
Jensen Hendler – Monster Energy Yamaha Star Racing 250 Team Manager
“It was a great night for the team. Our heat races were awesome. Haiden won the first one, and Cole won the second one, with Mosi (Michael Mosiman) right behind in second. Cole grabbed the holeshot in the heat and the main event, which was awesome. We had great starts on the night with all three guys, and they were all riding well. It’s unfortunate the way things played out. Both guys are hungry and want to win. It was great to lock in the championship tonight. This has been something Haiden’s been working for the past three years, so congrats to him. A lot of work goes into this, and I’m proud of the whole team. On the 450 side, we made some steps in the right direction, and Christian’s speed was there. We’ll go back to work and look to finish the season on a high note in Salt Lake.”

“It was a perfect night. I won the heat race and the main event. I had to fight for that main event win. It was two laps to go, and I was going to do anything for it. I ended up getting the championship a round early, which is crazy. This is something I’ve been manifesting since I was 12 years old, so to finally get it done, I’m hyped about that.”
Cole Davies – Monster Energy Yamaha Star Racing #100 YZ250F
“Man, I really wanted that win today, but I shouldn’t have put myself in that position. It really bums me out that he raced me that way, but I’ll be back in Salt Lake with something to prove.”
Michael Mosiman – Monster Energy Yamaha Star Racing #93 YZ250F
“There were lots of positives to take from the weekend. I was really proud of the work the team and I have done over the past few weeks. We didn’t give up on the Supercross season and continued to develop the bike and improve in some areas. I had a great heat race, and the main event was going well until I got into the lappers, which slowed me up quite a bit and ate up my gap on JuJu (Julian Beaumer). Then he hit me, and I went down, and I finished seventh. There was a fair amount out of my control in that race, but also, I have areas I need to improve to put myself in a better position in the future. We’ll build on the positives and improve on the weaknesses, and we’ll keep getting better.”
Christian Craig – Monster Energy Yamaha Star Racing #28 YZ450F
“I had a better day in Denver. My speed was there all day, and I was able to battle inside the top 10 for most of the main. A couple of mistakes cost me late in the race, but it was a step in the right direction. We’re looking forward to Salt Lake.”
