Deegan Heads All-Yamaha 250 Podium in Arlington
Monster Energy Yamaha Star Racing’s Haiden Deegan claims 250SX West Championship lead with Arlington Supercross victory, teammate Michael Mosiman joins him on the podium in third / Feb 24, 2025 /
It was a stellar night for the Monster Energy Yamaha Star Racing team at Arlington Supercross, with Haiden Deegan scoring the overall victory with a 1-1-2 score at the second Triple Crown event of the season. The back-to-back 250SMX Champion’s second win of 2025 has him leaving Texas with the red plate and a six-point lead in the Monster Energy AMA Supercross 250SX West Championship. Michael Mosiman also had a top night at AT&T Stadium, finishing third overall (3-2-7) to earn his first podium with the team. Round 5 of the Western Divisional 250 class was a roller coaster night for Cole Davies, but the rookie bounced back to score the win in the final main event, ending the night seventh overall with a 4-17-1 score. Completing the all-Yamaha podium was Coty Shock in second overall.
Deegan showed speed from the start in Arlington, Texas, ultimately qualifying second. Although he didn’t get off the gate as he had hoped in the first main event and had a tip-over early, the Californian made an impressive charge back from eighth to claim the win. In the second race, Deegan once again overcame adversity and fought his way back from 12th to score back-to-back wins at the Triple Crown. Deegan got a better start in the final main event in fifth, and from there, steadily made his way to the runner-up spot, scoring the overall victory and claiming the championship lead. He heads into the weekend break with a six-point lead before the Western Divisional 250 class joins up with the Eastern Divisional 250 class in Indianapolis for the first East-West Showdown of the season on March 8.
Mosiman had a solid start to the day at AT&T Stadium, qualifying seventh. From there, he got a good start in the first main event in fifth and rode his own race amidst the chaos to finish third. In the second main event, Mosiman grabbed the holeshot and led for most of the race, getting passed by his teammate Deegan on the final lap. In the final main event, he was fourth after the start and then, unfortunately, shuffled back to eighth on Lap 2. Undeterred, Mosiman made his way back to seventh to secure third overall and earn his first podium with the team.
Davies continued to impress as the rookie earned his first fastest qualifier honors. After the first gate drop of the evening, he found himself sixth behind his teammates and then was shuffled back to eighth. Davies kept pushing and crossed the line fourth to complete a Yamaha lockout of the top four. In the second main event, the 17-year-old came together with another rider after the start and found himself at the back of the field. Davies put his head down and charged his way to 11th, but unfortunately had another crash and would cross the line 17th. Despite the less-than-ideal gate pick for the final race, Davies got a great start and slotted into the runner-up spot early. He took over the lead on lap four and rode on to score the win by a comfortable margin, ending the night seventh overall and advancing to third in the championship, 22 points from the top spot.
Next weekend, the Eastern Divisional 250 class returns to action for Round 3 of the Monster Energy AMA Supercross 250SX East Championship and Round 8 of the 450SX Championship at the Daytona International Speedway on March 1.

“It was an awesome night for the team! We had a good qualifying, which set us up with some good gate picks for the main. Haiden struggled a bit with his starts but charged his way back and won the first two, which was awesome. He then brought it home with a second-place finish, taking the win and the championship lead. Mosiman rode great. He got some great starts, putting him in a good spot for the Triple Crown, and he ended up finishing third overall, which was great. Cole had a great start to the day and was the fastest qualifier. It was unfortunately a roller coaster night for him, with a couple of crashes in the second main, but he rebounded and got an amazing start in the third main and won the race. So yeah, the fastest qualifier, three main event wins, an overall win, a double overall podium, and the West Coast red plate - it can’t get too much better than that. We’re really excited about where we are at and are looking forward to another East Coast round and looking to keep the momentum rolling there as well.”

"It was a good night. Qualifying was pretty solid, and then in the first and second moto, I had to fight through the pack, but we were able to get the win, so that was cool. Then in the third main, we ended up getting second. It was a solid night with first overall and leaving with the red plate and a pretty good points gap, so I’m happy about it.”
Michael Mosiman – Monster Energy Yamaha Star Racing #93
“It was an awesome night here in Dallas. I haven’t had the best experiences here at this facility, so it was good to have a positive experience at Jerry’s (Jones) house. I had some family here, so I wanted to put on a show and did just that. I got great starts all night, and that definitely made the difference. I felt good. I felt strong. I like the Triple Crown format. I think it suits me well. I’m definitely looking forward to the next race.”
Cole Davies – Monster Energy Yamaha Star Racing #100
“It was a tough night for me in Dallas. I qualified first and came into the night really confident. I didn’t get off to a great start in the first main and struggled to get through the pack. In the second main, I got a really good start but got hit by another rider in the first turn and went down. I made my way through the pack, but then crashed again and really struggled and was pretty banged up. In the final main, I knew I had to reset. I had the 17th gate pick, which put me on the very outside gate, but I was able to make it work and came out third and made a couple of passes to get into the lead. That last race was a good bounce-back for me. I’ll be back stronger at Indy.”
