It's time for Round 12 of the 2019 Monster Energy AMA Supercross an FIM World Championship in Seattle! The Yamaha Track Map is looking awesome and there are a lot of storylines heading into the race. Cooper Webb is carrying a 14-point lead over teammate Marvin Musquin who won last weekend and will look to cut deeper into that lead. Seattle is typically soft and develops ruts, so look for the racing action to be as exciting as ever. In addition, the 250SX Western Division returns to action with Adam Cianciarulo leading the championship.
