Pole-sitter Kyle Busch led all 50 laps to win the first stage of the Brickyard 400.
Busch is seeking to win his first Cup race in his last 36 starts since capturing last year’s Brickyard 400.
Chase Elliott is out of the race after his No. 24 Chevrolet blew an engine on Lap 45. Elliott had begun dropping off the pace around Lap 20 and he was a lap down after an extended stop during the competition caution.
It is the first time Elliott has lost an engine in his Cup career.
The first caution of the race occurred on Lap 9 when Corey LaJoie hit the wall in Turn 3. During the caution the field was brought to pit road on Lap 12 ahead of severe weather.
The race was red flagged for lightning before it began raining. The red flag lasted one hour, 47 minutes and three seconds and was lifted at 4:47 p.m.
The race went back to green on Lap 18.
The competition caution originally scheduled for Lap 20 was pushed back to Lap 30.
Stage 2 will end on Lap 100 with the race scheduled to go 160 laps.
