Eli Tomac continued his dominance in the 450 class while the 250 class got another roster shake-up on Saturday during Round 5 of the 2018 Lucas Oil Pro Motocross Championship series at Muddy Creek Raceway in Blountville, TN.

Tomac kept his overall win streak intact after edging out Justin Barcia for the win. Tomac easily passed Ken Roczen for the lead in Moto 1 and checked-out then backed-off before settling for third in Moto 2 to take the win. Barcia found the speed needed to compete upfront finishing second in both Motos for second overall and Marvin Musquin finished third overall rebounding from a fifth in Moto 1 to take the checkers in Moto 2. Roczen, who grabbed the holeshot in both Motos finished fourth overall after a (3-4) day.

Jeremy Martin's bid for a third Championship in the 250 class came to an end after a brutal crash in Moto 2 resulted in a burst fracture of his L1 vertebrae. No loss of mobility but he's out for the season. His injury follows a season ending injury to Zach Osborne a few weeks ago and both top contenders for the 2018 title now sit on the sidelines.

Shane McElrath however got his first career overall win in Motocross on a (3-2) day and Dylan Ferrandis got his first Moto win and podium of the season after returning the week prior from a Supercross injury. Chase Sexton grabbed his first podium of the season taking third overall after an (8-4) day. Points leader Aaron Plessinger finished seventh overall and nearly lost his 20 point advantage over Martin who won the first Moto. Martin remains in second-place but with his season over Alex Martin is next in line 29 points back. Martin managed fourth overall despite some nasty crashes that resulted in losing the lead for both Motos.

Now that's style

Congratulations to Shane McElrath for winning his first Outdoor National round

Hold on Cameron McAdoo!

Now without a job, Jacob Hayes, the 2018 Champion of the now defunct Arenacross series, did pretty well taking 11th overall in the 450 class

Neat
