In the 250 Class, Monster Energy Yamaha Star Racing’s Haiden Deegan continued his winning ways and emerged triumphant once again to open the summer with three straight victories.

“Going into that second moto my legs were shot, but I dug deep and just kept telling myself to stay there [with the leaders]. I capitalized on a mistake by Hunter [Lawrence] and kept going after JCoop [Cooper]. I didn’t necessarily expect to be up here [in first], but it feels awesome after last weekend.”

Jett Lawrence, Team Honda HRC:

“That little [expletive] got me [laughs]. It was a good run. It was cool to go down to the wire. We made a big change over the week and I think it paid off for both of us [Jett and I].”

“It was an awesome day. I got both holeshots and led for 25 minutes. I tried my best, but they [the Lawrences] were riding too good. I gave it everything I had and I’m really happy with today’s performance.”

Justin Cooper, Monster Energy Yamaha Star Racing:

“I got a good start [in Moto 2] but Chance [Hymas] was ripping. I had to look at the big picture. We had the overall and now we have three [wins] in a row. The hard work is paying off.”

Haiden Deegan, Monster Energy Yamaha Star Racing:

“I’m speechless right now. I went over the finish line and just broke down. There was a point in time where I didn’t think this was possible. I’m just grateful to be here.”
