The MSR team that had been the class of the field suffered technical drama shortly after the midway point of the race, with the engine cover of the #60 Acura ARX-06 having to be taken off during a full-course yellow due to a suspected gearbox leak.
This dropped Simon Pagenaud down to third when the race went back to green, but the 2016 IndyCar champion made quick work of Pipo Derani in the #31 Action Express Racing Cadillac to move back up to second position.
