LAS VEGAS, March 10 (UPI) -- Defending series champion Ricky Stenhouse Jr. pulled away after the final restart Saturday and dominated from there in winning the Nationwide Sam's Town 300.
Stenhouse captured the championship in his second full year on the Nationwide circuit in 2011 and entered the race as the fifth-leading points producer early in the 2012 campaign.
After the seventh and last caution of the race at the Las Vegas International Speedway, Stenhouse and Mark Martin contested for the lead when the green flag flew.
Stenhouse led Martin into the first turn and within 15 laps had taken a 4-second lead. The final 39 laps of the 200-lap race were run under green and Stenhouse wound up finishing 5.9 seconds in front of Martin.
