BROOKLYN, Mich. (AP) — Ty Gibbs won his Xfinity Series-high fifth race this year and ninth of his two-year career Saturday at Michigan International Speedway.

The 19-year-old grandson of team owner Joe Gibbs, in the No. 54 Toyota, led 54 of the 125 laps on the 2-mile oval.

“I’ve had an awesome time on this series,” Gibbs said. “I work as hard as I can to be the best I can. I don’t really have any other hobbies.”

Justin Allgaier finished second followed by Noah Gragson, who won the pole and the first two stages at the New Holland 250.

Gibbs was scheduled to start sixth on Sunday in the NASCAR Cup Series race in the No. 45 Toyota for 23XI Racing, filling in for Kurt Busch, who was to miss his third straight race with concussion-like symptoms.

A.J. Allmendinger was aiming for his second straight Xfinity Series win this season and second in a row at Michigan. He led seven laps before finishing seventh.
