This is crazy. The crowd is going nuts and buzzing. Did we just see the closest finish in NASCAR Cup Series history????

NASCAR SAYS KYLE LARSON WON!!!!!! UNREAL!!!!!

LARSON TO THE OUTSIDE!!! WHO WON??? PHOTO FINISH!!

WHO WON???

Buescher has the lead!! WHITE FLAG!!!

Here we go. Overtime underway. Larson tries to make it three-wide on Hamlin and Hamlin gets stuck in the middle!! It's Larson vs. Buescher!!

PIT ROAD: Looks like Hamlin wins the race off pit road, followed by Buescher, Larson, Elliott...what happened to Truex? He lost eight spots because he is the first on four tires.

Hamlin is told 'vegetable' as the pit call and he has a deep sigh and says 'OK.'

Honestly I think Truex was about to pass Hamlin in the final laps anyway. But now what happens??

WHOA!! Caution!!! Kyle Busch spins!!!

Wow, where did Truex come from? He's suddenly up to P2. Larson down to P5 somehow...lost handling?

Hamlin last pitted on Lap 194...that was 64 laps ago.

Still 9 to go.

Chris Buescher told: 'I know we're asking a lot, but just keep working on it. If we have to give up the 5, I'm OK with it. Just make sure we get there.'

Gabehart to Hamlin: 'Manage that gap. I need it all.'

Has Hamlin saved enough fuel? It seems like at this point it's either going to be he makes it or Larson passes both Hamlin and Buescher.

Hamlin now leads by 1.3 seconds over Buescher with 12 to go. Dunno if Buescher went more into savings mode? Hamlin pulling away from both.

Larson actually losing ground now.

'80% lift, both straightaways. ... 5 is not coming.'

That's the latest from Gabehart. Puzzling why Larson can't quite get to these guys.

Hamlin continuing to be coached up on how much throttle he's using. Kyle Larson, -1.2 seconds behind Hamlin and Buscher, can go all out.

17 to go.

Fuel concerns seem to be growing on the 11 radio: 'I do need more. You've got to keep threading the needle.'
