Tony Kanaan currently leads the way in the ABC Supply 500 following an eventful first 100 laps at Pocono Raceway.
In the opening stages, pole-sitter Helio Castroneves dropped back at the start behind Josef Newgarden and Simon Pagenaud, but looked to recover the lead by going longer in his first stint.
However, this decision backfired for Penske when a full course caution was called on lap 29 when Jack Hawksworth lost a wheel, closing the pit lane before Castroneves and Pagenaud could pit.
As a result, the Brazilian was left outside of the top ten once he had pitted, and with a second full course caution soon following after Sebastien Bourdais crashed out, Newgarden appeared to be in control of the race.
Ahead of the second round of stops, Kanaan began to make his charge up the field to seize the lead from Newgarden. He could not keep Castroneves or Pagenaud back after the second pit cycle, though, dropping back down to third.
A third full course caution was called on lap 85 following a clash between Charlie Kimball and Jack Hawksworth on track, prompting all of the drivers out on track to pit. Castroneves managed to retain his advantage off pit road, leading now from Pagenaud and Kanaan upon the restart.
Kanaan managed to storm past Pagenaud and Castroneves to retake the lead when the race returned to green, with Ganassi teammate Sage Karam following his tow up into third place.
However, another caution soon followed when Tristan Vautier and Graham Rahal clashed, sending both drivers into the wall and out of the race in an incident that will have massive implications on the title battle.
With Juan Pablo Montoya running fifth and Scott Dixon in ninth, Rahal looks set to drop back in the standings ahead of next weekend’s season finale at Sonoma.
