Turns three and four have been Calamity Corner in today's Pure Michigan 400 at the Michigan International Speedway.
The first caution was for David Gilliland's spin off four. Then Bobby Labonte was spun while racing hard with Juan Pablo Montoya, and race leader Mark Martin wound up getting taken out as a result.
In the restart from Martin's accident, Marcos Ambrose got into Regan Smith in turn three, sending Smith into the wall and ruining his bid for a third-straight top-10 finish. Most recently, Joey Logano got a tap from Montoya and slid up the hill into the wall, then slapped the wall in the same spot a lap later to draw the caution.
Among all the carnage are some frayed tempers. Jeff Gordon launched into a profanity laced tirade directed at teammate Dale Earnhardt Jr. after Earnhardt made a three-wide move beneath Gordon on a restart. Gordon added that he should have wrecked his Hendrick mate.
Gordon has now dropped a cylinder on his No. 24 Chevy, the same problem that befell Tony Stewart's car that carries the same Hendrick horsepower as Gordon. Gordon's teammate Jimmie Johnson had to change engines Saturday.
After 95 laps, Martin Truex Jr. holds the lead ahead of Greg Biffle, Sam Hornish Jr. - who had not turned a single lap in that car until he took the green flag today - Matt Kenseth, and Kevin Harvick.
