Helio Castroneves in the Meyer Shank Racing Acura made a brilliant restart from fourth place on a restart 3hr30min into the race, but suffered a sudden deflation of his left-rear and lost a whole lap limping back to the pits.
That allowed Will Stevens in the Acura ARX-05 of Wayne Taylor Racing back into the lead ahead of Ganassi’s Renger van der Zande, Tristan Nunez in the Action Express Racing Whelen Engineering Cadillac, Marcus Ericsson in the second Ganassi Caddy, Mike Rockenfeller in the Ally AXR Cadillac and Ben Keating doing double-duty in the JDC-Miller MotorSports entry.
