Sparta, Ky. Series leader Scott Riggs passed pole-sitter Jack Sprague with nine laps left and went on to win the NASCAR Craftsman Truck Series Kroger 225 on Saturday night.
Sprague, who led much of the race, passed Riggs to regain the lead on lap 140, but dropped behind on the following lap when his truck developed engine problems.
The victory at Kentucky Speedway was Riggs' third of the season, extending his lead in the standings over second-place finisher Joe Ruttman and Sprague.
With his third-place finish, Sprague became the first driver in series history to reach $4 million in earnings.
Travis Kvapil, who started in 18th position, finished fourth. Dennis Setzer was fifth, and Ricky Hendrick, who started on the outside of the front row and last week became the youngest winner in series history, finished sixth.
Sprague and Ted Musgrave traded the lead several times during the first 100 laps, leaving the rest of the field more than five seconds behind and struggling to catch up.
Following a handful of short caution periods and a series of pit stops, Musgrave retook the lead on lap 118 only to be bumped into the wall while trying to pass Matt Crafton on the outside.
Riggs, in the No. 2 Team ASE Racing Dodge, took the lead at that point, followed by Sprague and Randy Tolsma.
Lance Norick made contact with the wall with six laps to go, forcing the seventh caution period of the night.
The race went back to green with only three laps remaining, and Riggs held off Ruttman and Sprague following the restart to claim his third career victory.
Musgrave, who came into the race with a series-leading four victories and the No. 4 position in the points standings, led 76 laps before hitting the wall.
He finished 24th.
