Monster Energy Kawasaki’s Eli Tomac has won a mud-filled main event at San Diego’s fifth round of the Monster Energy AMA Supercross and FIM World Championship, earning the 450SX points lead in the process.

Tomac pushed through the demanding encounter, capturing victory over Red Bull KTM Factory Racing’s Marvin Musquin by 4.199s, as Ken Roczen (Team Honda HRC) completed the podium in third.

Justin Bogle (Rocky Mountain ATV/MC KTM) was an impressive fourth – his best finish of the season – while Australia’s Chad Reed (JGRMX Yoshimura Suzuki Factory Racing) rounded out the top five. Former points leader Cooper Webb (Red Bull KTM Factory Racing) was eighth, demoting him to fourth in the standings.

In the 250SX West class, Adam Cianciarulo (Pro Circuit Monster Energy Kawasaki) gained the points lead after capturing his third victory of the series, comfortably defeating teammate and podium newcomer Garrett Marchbanks (Monster Energy Pro Circuit Kawasaki) and third’s Jimmy Decotis (JGRMX Yoshimura Suzuki Factory Racing).

The top five was completed by Shane McElrath (TLD Red Bull KTM) and Jess Pettis (KTM), while former points leader Colt Nichols (Monster Energy Yamalube Star Racing Yamaha) was 10th in the treacherous conditions. The AMA Supercross championship heads to Minneapolis next weekend, marking the first east coast round of the championship.
