As the 2017 Monster Energy Supercross Series moved east to Arizona’s desert, fans and riders prepared for the first race without the injured Ken Roczen. With the Honda rider getting multiple surgeries in Colorado to repair his badly broken arm, the rest of the field lined up for the first real indoor race of the year. With a more traditional track inside the University of Phoenix stadium, riders were able to use the multiple 180 degree corners, as well as the long whoop section for passing. When all was said done at Round 4, Kawasaki riders Justin Hill and Eli Tomac stood atop the podium in their respective classes. As the series now moves northwest to Oakland for the final California round of 2017, we take a look at what went down on Saturday evening through the lens of Krystyn Slack.
