Florida resident Ryan Hunter-Reay saw his 2012 Indy 500 come to a disappointing finish at Lap 125 when a mechanical failure caused him to drop out of the race.
Hunter-Reay began the day in third place, falling back to as far as fourteenth, before making another move toward the front of the pack before the suspension in his car thwarted his comeback attempt.
His official final standing in the race is 27th place, far from his career best of sixth in his rookie race in 2008.
Takuma Sato has emerged during the second half of the race to take control of the lead. He has Dario Franchitti, Scott Dixon and Marco Andretti hot on his trail.
