Kevin Harvick's domination of NASCAR's Busch Series continued Saturday at Kansas Speedway with a victory in the sold-out Yellow 300.
Harvick won his seventh race of the season by holding off fellow NASCAR NEXTEL Cup Series drivers Matt Kenseth, Kyle Busch, Tony Stewart and local favorite Clint Bowyer of Emporia, Kan.
Harvick extended his series lead over Carl Edwards to a staggering 729 points, the equivalent of four races.
Harvick will go for the rare NASCAR double in Sunday's Banquet 400 presented by ConAgra Foods at Kansas Speedway. Kasey Kahne will start from the pole. The green flag drops at 1:10 p.m.
"Our car was really good in practice on the Cup side, today we were able to keep up with the (changing conditions)," he said. "I like our chances."
Said Kenseth, who couldn't catch Harvick in a late restart: "He's hard to beat in those Busch cars."
Saturday's victory extended the domination of Richard Childress Racing in 2006. The team has won 15 races in NASCAR's three top series ¿ NEXTEL Cup, Busch and Craftsman Truck Series. The previous record of wins in a season was 13, set by the same team in 1995.
Harvick has won 11 of those races (four in NEXTEL Cup, seven in Busch), Burton three (one NEXTEL Cup, two Busch) and Bowyer one (Busch).
Harvick and Burton have combined to win the past three NEXTEL Cup races.
"It's one of those years where everything has gone our way," Harvick said.
Aaron Pierce won the KansasSpeedway.com 100 for the U.S. Auto Club Weld Racing Silver Crown Series. Bud Kaeding was crowned series champion.
