Make That Four in a Row for Haiden Deegan
Monster Energy Yamaha Star Racing’s Haiden Deegan continues to raise the bar in the 250SX West Championship, further strengthening his title defense / Feb 7, 2026 /
It’s been full steam ahead for Monster Energy Yamaha Star Racing’s Haiden Deegan since San Diego Supercross. The 20-year-old has been unstoppable, and at Round 5 of the Monster Energy AMA Supercross 250SX West Championship, he delivered another masterclass performance at State Farm Stadium in Glendale, Arizona.
The reigning champ continued to add to his list of accomplishments in what is his final title campaign aboard the YZ250F. Thus far in 2026, Deegan has notched four consecutive wins – including a Triple Crown sweep in Houston – four heat race wins, and four straight fastest qualifier honors. He added to the momentum in Glendale with a pair of holeshots, one in the heat race and one in the main event, allowing him to lead from start to finish on the technical track.
“Four in a row, and it was another perfect day, so yeah, it’s amazing,” Deegan said about the day. “The track was pretty technical in the main event, pretty slick, but we were able to make it happen. I finally pulled a holeshot in the main event, so that was very nice. That’s a wrap on Glendale. Now we’re on to Seattle.”
Deegan now holds a commanding 27-point lead at the halfway mark of the 250SX West Championship. With one round remaining before the series break, he’s focused on keeping the momentum rolling while also looking ahead to what’s next.
”I’m so excited to get on a 450 and start getting ready for outdoors,” Deegan said. “These races have been solid. It’s been lots of hard work with the family and the team, and my bike has been amazing. Man, this feels good. The hard work that I put in during the preseason, it paid off, and it shows you who works and who doesn’t.”
After a tough outing in Houston, Michael Mosiman rebounded with a strong performance in Glendale. The Californian got a solid start in his heat race, running third before making the pass for second on Lap 3 and riding a smart race to the finish. In the main event, Mosiman once again got a strong start and slotted into second behind Deegan, holding the position for much of the race. Late pressure saw him lose spots to Levi Kitchen and Cameron McAdoo in the closing laps, ultimately finishing fourth. The result, however, moved him back into second in the championship standings.
“Glendale delivered a solid points night,” Mosiman said. “Qualifying wasn’t where I wanted it to be, but I had confidence in my riding and my abilities going into the main event. My starts were strong, which was a big focus for me after last weekend, so that was a positive takeaway. Losing the podium in the final laps was frustrating, and that’s on me. I know exactly where I need to improve, and I’m confident I can make those adjustments to finish races stronger. I’ve worked hard to get back to a place where I’m consistently fighting for podiums, and the same determination and resilience that got me here will keep driving me forward. A big thank you to the team for their effort and support.”
Max Anstie’s night proved challenging. He got a flying start to the first heat race of the evening, but unfortunately went wide and off track, rejoining towards the back of the field. The British rider put his head down, making an impressive charge through to fifth, but then a bad start in the main event made for an uphill battle. In 16th after the opening lap, he charged his way through to eighth by the halfway mark, where he would ultimately finish.
“It was not a good day today,” said Anstie. “I got a bad start in the main and only made it back to eighth. I did all that I could, but it wasn’t good enough tonight.”
“It was definitely nice for Haiden to leave here with another pretty perfect night,” said Wil Hahn, Monster Energy Yamaha Star Racing’s 250 Team General Manager. “Mosi (Michael Mosiman) was riding well and unfortunately lost the podium at the end of the race, but he’s second in the championship. Max just had an off night. We need a nice reset and will come back next weekend.”
Monster Energy Yamaha Star Racing will be looking to finish on a high note before the Western Divisional 250 class goes on break. They head to Seattle, Washington, next weekend for Round 6 of the Monster Energy AMA Supercross Championship and the Monster Energy SMX World Championship series at Lumen Field on February 14.
