With Busch’s help, Blaney took the lead on the final restart, then bobbed and weaved his way around Michigan International Speedway to beat Byron by 0.077 seconds. It was the narrowest victory margin in a Cup race at this track since electronic scoring began.
“I wouldn’t say we had the best car,” Blaney said. “We got pretty good, to a point where I thought we could run fourth or fifth and it just worked out to where he could give us a push and it just worked out.”
Blaney won for the second time this season and sixth overall, capping a big weekend for Team Penske, which won Saturday’s IndyCar race in suburban St.
