Following an exciting night of racing in Oakland, the sixth round of the 2018 Monster Energy Supercross series returned to Southern California for the final time in San Diego. Title favorites had begun to develop in each class, but the storylines were no less interesting and neither Aaron Plessinger or Jason Anderson could guarantee their hold on the points lead. Particularly, for the 250 SX West Coast series, this would be the final round before the East Coast kicks off in Arlington. For this reason, momentum heading into the break would be valuable for whoever could exit Petco Park with a win.
