Trevor Bayne dominated from the pole, and the 2011 Daytona 500 champion won Saturday in his ARCA Series debut.

Bayne entered the race at Pocono Raceway for more practice time ahead of Sunday's NASCAR Sprint Cup race. Even with 71 career Cup starts, Bayne had never turned a lap at the 2 1/2-mile tri-oval track. He drove Saturday for Cunningham Motorsports.

Bayne has struggled in Cup in his first full season with Roush Fenway Racing. He's 31st in points with no top-10 finishes.

His win capped a big week for his family. Bayne announced on Twitter that he and wife Ashton are expecting their first child.

Bayne says the couple "timed it right" to have the baby in December during the offseason.

Grant Enfinger was second and Mason Mitchell was third.
