Haiden Deegan swept three of the first four rounds, but he still had something to prove after Chance Hymas had a truly perfect ride at Thunder Valley by winning qualification, holeshotting both races and leading every lap. Deegan is not happy to acknowledge anyone with a better record, so he proved his point at The Wick 338 in Southwick with his own absolutely perfect round.
Deegan yarded the field in both qualification sessions, earned holeshots in both motos, and led every in route to his weekend sweep.
When asked by Jason Thomas what keeps him motivated and if he is thinking about 2026, Deegan responded: “Probably Fortnite and the after party, to be honest. Nah, I’m just playing. No, I’m going to lock out some Fortnite this week. I had fun at [their] function last week.”
Deegan now has a greater-than full round points lead over the Motocross competition. His advantage over second-place Jo Shimoda is 58 points.
Tom Vialle was scored second overall after finishing third in both motos.
“I used a lot of energy in the first moto, after my crash,” Vialle said. “So I had to come back from pretty far. Got a little tired in the second one. The track was pretty tough and gnarly. Second overall was the best I could do today, so we have to move on to the next weekend.”
Levi Kitchen secured the final overall podium spot with results of second in Moto 1 and fourth in Moto 2.
“To be completely transparent, I kind of had a hard time eating today and I started chugging some fluids to get going and like three laps in, I got the worst stich in my stomach and I was riding all hunchbacked,” Kitchen said after the race. “Then, I just tried to fight through it and get a podium.”
Michael Mosiman showed both consistency and speed to finish fourth overall with a 4-5. He missed the podium because of an overheating bike in the first race.
“We’ve had bike issues now a couple of rounds, and the guys are working really hard to get it fixed and they are one of the best teams in the paddock,” Mosiman said. “It’s just an unfortunate situation, but I’m building. This is a comeback year for me and it’s going according to plan.”
Jo Shimoda overcame a poor first moto to finish second in Moto 2. He won the second moto in each of the last two years, but was forced to settle for second in Moto 2 and a crash in the first race relegated him to fifth overall.
In-Race Notes
If Deegan has had any weakness in 2025, it was his inability to earn holeshots. Deegan will not accept any disadvantage, however, and he led the field under the holeshot banner in both motos at The Wick.
Kitchen came out of the gate slowly, but overcame that mistake quickly. He kept Deegan in sight for the first couple of circuits and finished Lap 2 only 2.4 seconds behind.
Shimoda, who won the second Southwick moto in each of the past two seasons, kept his bike upright on the first lap of this race and settled into third quickly.
Vialle also had trouble in the first moto with an early crash while battling Michael Mosiman for second. He was just outside a podium-contending position on Lap 3 in fourth.
Jalek Swoll rode fifth in the opening laps.
Kitchen was unable to keep Deegan in sight as the leader built an 8.6-second lead, so in response, Shimoda got around him on Lap 4. Shimoda lost some pace making the pass and lost another second.
Vialle closed the gap on Lap 5 and took third away from Kitchen.
Mosiman had a strong start in Moto 1. He wasn’t quite as fast in the early laps of Moto 2, but he moved into sixth with an eye on the top five. Peacock’s Will Christien revealed that Mosiman’s fade on the final lap of the first race was due to an overheating bike.
Second-place Shimoda was able to stabilize the gap and keep it under 10 seconds. He’s in a comfortable position 15 seconds ahead of third on Lap 9.
On that same lap, Mosiman caught Kitchen for fourth and they swapped the position a couple of times. This battle is nearly seven seconds in front of Swoll.
Shimoda kept the deficit under 10 seconds, but it was Deegan who took the checkers first.
Vialle finished third behind Shimoda.
Fourth-place Kitchen and Mosiman rounded out the top five.
