Deegan Wins 250 East/West Showdown in Salt Lake City
Monster Energy Yamaha Star Racing’s Haiden Deegan finishes the season with a dominant victory in the East/West Showdown / May 12, 2025 /

Monster Energy Yamaha Star Racing’s Haiden Deegan finished the season in style, scoring a dominant victory in the East/West Showdown at the Monster Energy AMA Supercross season finale at Rice-Eccles Stadium in Salt Lake City, Utah. Michael Mosiman made an impressive charge back to finish fifth, with Nate Thrasher coming back from a tip-over to cross the line 13th. Despite feeling less than 100% after a couple of crashes in qualifying, Christian Craig soldiered on to finish 11th. It was a stellar season for both 250 and 450 teams, that in addition to Deegan’s 250SX West Championship and Cooper Webb’s 450SX Championship, Yamaha Motor Corporation, U.S.A., earned the Monster Energy AMA Supercross Manufacturer’s Cup.
On the heels of securing the 250SX West Championship a weekend early, Deegan hit the ground running in Salt Lake City, topping the first session of qualifying and ultimately finishing second in the combined times. In the 250SX West Heat Race, he grabbed the holeshot and led the first half of the race, but would finish in the runner-up spot after getting passed on Lap 5. In the main event, Deegan grabbed another holeshot and set the pace up front to build a comfortable gap. The newly crowned champ rode his YZ250F to a dominant victory, crossing the line with a healthy 9.255-second lead. It was a stellar season that saw the 19-year-old earn four wins and make an impressive nine trips to the podium over the 10-round season.
Mosiman qualified 11th and was sixth after the start of the 250SX West Heat Race. The Californian kept pushing and made his way to fourth, where he would finish. In the main event, he did not get off the gate as he had hoped and found himself 11th after the opening lap. Undeterred, he put his head down and advanced to eighth by Lap 4, and then steadily made his way to sixth. In the final laps, he continued to battle for position and crossed the line fifth, ending the season seventh in the Western Regional 250 class points standings.
It was a tough start to the day for Thrasher. With a less-than-ideal gate pick after qualifying 15th, he found himself seventh on the opening lap of the 250SX East Heat Race. The Tennessee rider continued to push, making his way to fifth on Lap 3 and then to fourth in the final laps. He had a good start to the main event in fifth, which he maintained for the first five laps. As the race wore on, he was shuffled back to 10th, and then would have a tip-over after the finish line and rejoined in 14th. Thrasher went back to work and was able to make his way to 13th in the final laps, salvaging points to finish the year fourth in the 250SX East Championship. Although it was a rollercoaster season for Thrasher, he brought his career 250SX win tally to six after winning the Birmingham Supercross and made two trips to the podium.
Craig had a good start to the day at Rice-Eccles Stadium and was third in practice. Unfortunately, the Californian had a couple of crashes in 450SX qualifying and was 10th in the combined times. He had a good start to his heat race in fourth, where he rode for the first six laps, but he ultimately dropped back to sixth. Feeling less than 100% after his crashes in qualifying, Craig did what he could. In 12th after the opening lap of the 450SX Main Event, he kept pushing and advanced to 11th a couple of laps into the race, and maintained the position to the checkered flag.
Davies showed strength from the start, topping the timesheets in 250 practice and was second in the first 250SX West qualifying session. Unfortunately, the young New Zealander was sidelined from the final round after an on-track incident with another rider during that first qualifying session. He sustained a broken arm and broken nose from the crash, and underwent a successful surgery on Sunday to repair his arm. An update on his return will follow at a later date. Despite missing the final round, Davies finished third in the 250SX West Championship. It was a standout debut season, where he scored two wins and a total of four podiums, for which he was bestowed the Monster Energy AMA Supercross Rookie of the Year Award for his outstanding achievements.

Jensen Hendler – Monster Energy Yamaha Star Racing 250 Team Manager
“What a way to end the season. Haiden had an awesome race in the East/West Shootout, grabbed the holeshot and led the whole thing. It feels great to finish the season with a win, and we’re looking to carry the momentum into the outdoor season. We’re bummed that Cole got hurt, but what a season for him as well with a couple of wins as a rookie. It’s a well-deserved Rookie of the Year award for him, and we’re excited to see what he can do in the future. It was an up-and-down year for Nate, and unfortunately he finished 13th tonight, but it was great to see him get a win this year. Mosiman had a great ride coming back to fifth, and Christian did what he could after his qualifying crashes and was just shy of a top 10. We’re looking forward to the weekend off, and then it’s on to the outdoors.”
Haiden Deegan – Monster Energy Yamaha Star Racing #38 YZ250F
“Tonight was solid. I rode well in the main, and that’s where it counted. I just wanted to put in a dominant last race, and we got that done. I think we won by 10 seconds, so that was pretty cool. There was a lot of chaos behind us, but we got the holeshot and were able to take off. I’m happy with the day and the season. We got the West Championship and finished with a win tonight. I’m looking forward to the outdoors.”
Michael Mosiman – Monster Energy Yamaha Star Racing #93 YZ250F
“I was really proud of how I fought in the main event in Salt Lake. I was in 11th place on the first lap and made some great passes to finish in fifth. It was awesome to carry the momentum from Denver and to continue building confidence leading into the outdoors. I’m super thankful for the team’s support throughout the year and for working with me as I progress.”
Nate Thrasher – Monster Energy Yamaha Star Racing #41 YZ250F
“It was a very up-and-down season for me. I just have to be better, plain and simple. I’m ready to go have some fun outdoors.”
Christian Craig – Monster Energy Yamaha Star Racing #28 YZ450F
“I felt really good starting the day off in Salt Lake, but unfortunately had two big crashes in qualifying and was pretty banged up for the night show. I did what I could and was really close to a top 10.”
