A hopeful return to form for race leader Josef Newgarden was undone in an instant after a vicious mid-race crash with rookie Louis Foster.
Foster was running five cars ahead of Newgarden on lap 131 of Sunday’s race when his No. 45 washed up into the outside wall in the dirty air behind Santino Ferrucci in turn 4. Unable to control his damaged machine, Foster spun down into the inside wall on the front stretch.
