Regan Smith got the bump-drafting help he needed from Trevor Bayne and beat Brad Keselowski to the finish line by .013 seconds to win Saturday's season-opening NASCAR Nationwide Series DRIVE4COPD 300 at Daytona International Speedway.

In a race that went one lap beyond its posted distance of 120 laps because of a late caution involving Chad Boat and Eric McClure, Smith got help from Bayne in the outside lane and arrived at the stripe in his No. 7 JR Motorsports Chevrolet less than three feet ahead of Keselowski, who was drafting with fourth-place finisher Kyle Busch.

Bayne ran third, as he and Smith side-drafted Keselowski and Busch in the inside lane just enough to give Smith a miniscule advantage.

The victory, Smith's fourth in the series and his first at Daytona, was a race of redemption for the 30-year-old driver, who was right in the middle of the last-lap crash in the 2013 season opener.

Notes: The finish was the seventh closest in NASCAR Nationwide Series history and second closest at Daytona. The closest finish at the 2.5-mile superspeedway was Tony Stewart's victory by .007 seconds in 2011… Rookie polesitter Dylan Kwasniewski ran eighth in his Daytona debut.
