NEWTON, Iowa (AP) -- Trevor Bayne rallied to win the rain-plagued NASCAR Nationwide series race in Iowa on Sunday, becoming just the third series regular to win this season.

The victory capped a memorable week for Bayne, who got married on Tuesday and picked up his first win of the year five days later.

Austin Dillon, who conceded the lead to Bayne with 11 laps to go, was second. Elliott Sadler was third, followed by Sam Hornish Jr. and Kyle Larson in the first Nationwide race of the year without a Sprint Cup driver.

The race had been scheduled for Saturday night before being washed out by rain. Bad weather forced a 70-minute delay two-thirds of the way through Sunday's race.

Dillon won his third straight pole on Saturday afternoon, tying a series record last matched by Bayne in 2010, and the No. 3 car led for more than 200 laps on Sunday.

But Dillon's car also tended to run out of steam on long runs, and the race stayed caution-free for the final 72 laps.

It was hardly surprising that the No. 6 car from Roush-Fenway Racing was there to take control and give Ford its 200th win in the Nationwide series.

Bayne's hard-charging pursuit of Dillon paid off with 13 laps left as the race's dominant cars briefly rubbed while fighting for the lead. Bayne took over two laps later and cruised to the fourth win in five starts for the No. 6 car in Iowa. The previous three victories came from Ricky Stenhouse Jr., now a Sprint Cup regular.

Dillon took control from the outset, leading by as much as a third of a lap on Iowa's .875-mile oval. Bayne eventually moved into second - but he lagged over five seconds behind Dillon.

Dillon then went low on a restart and slipped past Bayne, who rubbed up on Regan Smith, to retake the lead just before the skies opened and the red flag came out.

Saturday's postponement forced Joey Logano, the lone Sprint Cup regular in the field, to skip Iowa for Pocono on Sunday, with Ryan Blaney driving the No. 22 car.

Joe Nemechek also chose Pocono over Iowa. Kevin Lepage took over for Nemechek in the No. 87 car, and he and Blaney started from the back because of the driver changes.

Blaney finished ninth.
