Sparta, Ky. ? Mike Skinner completely dominated Saturday night’s Built Ford Tough 225, leading 135 of 150 laps to earn his series-leading fourth victory of the season.

With the victory, Skinner became just the second driver 50 years or older to win a series race and set a record by leading his 13th consecutive race every one of the year. He celebrated his 50th birthday two weeks ago.

Skinner’s championship lead grew to 164 points over Ron Hornaday Jr., who finished 10th. Skinner took the lead for the final time on the 105th lap when he passed defending series champion Todd Bodine.

He held a 5.57-second margin of victory half a straightaway over Travis Kvapil’s Ford. Kvapil in turn edged Ted Musgrave as the pair battled for the runner-up spot over the race’s final 10 laps.

Skinner averaged 127.175 mph in the series’ second-fastest race. He won $86,425 in recording his 23rd victory in a 142-race career.

Six different drivers exchanged the lead 10 times.

Skinner has completed every one of the season’s 2,193 laps and has finished out of the top 10 just once.
