Monster Energy AMA Supercross, an FIM World Championship, hosted Round 13 in front of 55,407 fans inside CenturyLink Field in Seattle for one of the slimiest, slickest races in history.

The Monster Energy Kawasaki of Eli Tomac found itsway to a third-place start, battling back and forth with Team Red Bull KTM Factory Racing’s Marvin Musquin for second with Rockstar Energy Husqvarna Factory Racing’s Jason Anderson out front for the first five laps. After Tomac passed Musquin, a mistake by Anderson handed Tomac the lead for the remaining six laps of the 11-lap race. Anderson held on to second ahead of Musquin who rounded out the podium with a third-place finish.

“It’s just one of those tracks where you just have to either ride it and have fun or you’re just in misery, and today we were having fun,” Tomac said after the race. “That was, by far, the craziest Supercross moments I’ve ever been in. It felt like I was in the backyard just having fun and riding in the mud, and that’s how you had to treat it.”

Monster Energy/Yamalube/Star/Yamaha Racing’s Aaron Plessinger ran away with the 250SX Class win, leading from the start of the 8-lap Main Event. GEICO Honda’s Chase Sexton earned a career-best second-place finish ahead of Monster Energy/Pro Circuit/Kawasaki’s Adam Cianciarulo in third.

“That was fun,” Plessinger said on the podium. “That was a sick race; it reminded me of a lot of GNCCs, so it was good to get out there and have some fun and rip some ruts. There were sometimes where the ruts were two feet deep, and you just had to pick a good line … I knew I could do it here. I love Seattle. I love all these fans here; they make it exciting.”

Aaron Plessinger extends his Western Regional 250SX Class points lead with his fourth win of the season in Seattle.
