HRC rider Ken Roczen has dominated the triple crown in Glendale. The former MX2 World champion went 1-1-1 to lead home Eli Tomac, who scored 2-2-3 results and Jason Anderson with 5-3-2 scores. 

Also to impress was Cooper Webb and Justin Barcia, who rounded out the top five. Roczen now has 92 points for the championship lead with Eli Tomac on 84 points.

Monster Energy Kawasaki rider Austin Forkner won the 250 class with 1-1-3 scores ahead of Dylan Ferrandis 2-2-2 and Michael Mosiman 4-4-6. Justin Cooper 17-9-1 still leads the championship points after his ninth place finish, but just three points seperate him and Ferrandis, 86 points to 83 points.

Chad Reed continued to fail with a 20th racing position. His career more or less over as he winds down his amazing career, while Zach Osborne also looked bad in 16th place and 22-11-18.
