DETROIT (AP) — AJ Allmendinger had a rough weekend in the Motor City.
The Penske Racing driver crashed on the opening lap for the second straight day at the Detroit Grand Prix.
"I'm embarrassed," Allmendinger.
He was in a pack of cars when he hit a wall Sunday, saying he made a mistake. Allmendinger also took the blame for getting squeezed between two cars in a crash Saturday.
"It's the start of the race trying to be aggressive," Allmendinger said.
He finished seventh in the Indianapolis 500 last Sunday, losing a shot to fare better because his seat belt became undone.
Allmendinger has driven a limited NASCAR schedule since getting suspended for a failed drug test last year. Penske fired Allmendinger, but gave him another chance in IndyCar and is extending another opportunity in stock cars this summer. Penske Racing plans to put Allmendinger in NASCAR Nationwide Series road course races this month and in August.
