DOVER, Del. — Kyle Busch climbed out of his truck, bowed to the crowd and sprayed beverages at his crew.
Busch has the familiar victory celebration down pat — a perfect end during a perfect season.
Busch made it 4-for-4 in the NASCAR truck series, dominating again to win Friday's Lucas Oil 200 at Dover International Speedway. He also won this year in his other three series starts, at Daytona, Kansas and Charlotte.
"I don't know that there's anything I can say that I'm doing that's allowing us to win those races," Busch said. "Just unload and expect to win races."
Cruising in the No. 51 Toyota, Busch led 150 of 200 laps on the mile track. Busch won from the pole for the third time this season.
"I've enjoyed being able to run up front and lead laps," Busch said.
Busch won his fifth straight series race overall, dating to the 2013 season finale at Homestead. He has 39 truck victories.
"We're just trying to work on our stuff and make it faster," he said. "All that work is paying off this year."
Busch can make it a tripleheader sweep with wins in today's Nationwide race and Sunday's Sprint Cup race.
Matt Crafton, the defending series champion, won the only other Truck race at Martinsville. He was running second when he smacked the Dover wall with about 43 laps left, ending his race. It was the first time he hadn't finished in 47 series starts.
Ryan Blaney was second, followed by Johnny Sauter.
"I don't think anyone was going to catch the 51," Blaney said. "He was something else."
Busch will skip the next two series races and return for the June 26 race at Kentucky.
Sprint Cup: Brad Keselowski turned a track-record lap of 164.444 mph to get the pole for Sunday's race at Dover.
Keselowski earned his second pole of the season, fifth of his career. He also has started second six times in 2014.
"It's been a good year for qualifying," Keselowski said, "And I would say most years, that has not been the case."
Keselowski turned a lap of 164.444 mph followed by Kyle Busch, Joey Logano (Keselowski's Penske Racing teammate) and eight-time Dover winner Jimmie Johnson.
NHRA: Doug Kalitta had a run of 3.756 seconds at 327.03 mph to lead Top Fuel in the first day of qualifying at the Summernationals in Englishtown, N.J. Cruz Pedregon (Funny Car), Allen Johnson (Pro Stock) and Eddie Krawiec (Pro Stock Motorcycle) also led their classes.
