Indianapolis, IN (Best E Casino) - Tony Stewart leads Sunday's Allstate 400 at the Brickyard after 80 of 160 laps. The No.20 Home Depot Chevrolet has a 0.695-second lead on Juan Pablo Montoya.

Matt Kenseth, Kevin Harvick and Jeff Burton make up the top-five.

Reed Sorenson led the field to the green flag to begin 160 high-speed laps at the famed Indianapolis Motor Speedway. It was a clean start and Sorenson led the first lap as has every pole winner since they started coming here in 1994.

On the move early on was Indiana native Stewart, who started 14th, but cracked the top-five in the first 10 laps. By lap 15 he was third behind Sorenson and Dale Earnhardt Jr.

When Jeff Green spun on lap 16 Stewart's pit crew helped their driver gain the final two spots and put the 2005 winner into the lead.

On the restart, "Junior" was all over Stewart and as they reached the front straight he made the move to the inside for the lead. Just after the pass Ryan Newman slammed the wall to bring out a second caution flag.

Earnhardt Jr. opened his lead up to two seconds as the field passed the 30-lap mark. The lead hovered around two seconds as Earnhardt Jr. and Stewart exchanged fastest laps.

Then on lap 39 Kasey Kahne clipped the corner of Tony Raines and both drivers spun to bring out another caution flag.

On lap 46 defending champion Jimmie Johnson got into Jamie McMurray and their spin collected Scott Riggs, 2002 Brickyard winner Bill Elliott and Ricky Rudd.

When the race finally restarted Stewart got around Earnhardt Jr., but once again a crash interrupted the flow of the race. Then again on lap 62 Johnson slammed the wall and this time the No.48 Hendrick Motorsports Chevrolet burst into flames to end his day.

"The hit wasn't too bad, but the flames had me nervous," said Johnson, who quickly pulled his car onto the infield. "I could feel the right-side of my face getting hot."

On the third of the three incidents, the field strategies split. Six drivers including new leader Kyle Busch stayed out and inherited the top-six spots on the track. Montoya took fuel only and was the first of the pitting cars to return to the track in sixth and Stewart (two tires) came out seventh.

Another caution flag and those that hadn't stopped did so giving the lead back to Stewart.

Currently off the track are: Johnson, Kyle Petty, Johnny Sauter, Casey Mears, McMurray, J.J. Yeley, Kahne, Raines, Newman and Jeff Green.
