Dover, Del. ? Greg Biffle took the lead for the first time with 21 miles to go and then drove away from the field to win the rain-delayed NASCAR Busch series race Monday at Dover International Speedway.

It was Biffle’s 14th career victory and second on the Monster Mile. The win also gave team owner Jack Roush a Dover sweep of NASCAR’s top two series’ events, after Mark Martin also used a late charge to prevail in Sunday’s Nextel Cup race.

The MBNA America 200 began Saturday but was postponed after just 28 of 200 laps — and a delay of 5 hours, 10 minutes — with Bobby Hamilton Jr. holding the lead.

When the race resumed Monday, a number of drivers took turns on the lead. Martin Truex Jr. led a race-high 75 laps, but he needed fresher tires to overtake David Green with just under two miles to go to finish second.

Biffle, who ran among the top 10 throughout the day despite complaining that the handling on his No. 60 Charter Communications Ford was “loose,” said crew chief Brad Parrott helped steer him through some rough stretches.

“Brad told me early on, ‘Just take it easy, take it easy,'” Biffle said. “Then we made some adjustments to the car, and it just took off.”

Biffle, the 2002 Busch Series champion, passed Green on the low side of the track on lap 179 and then pulled away from the field to win by a comfortable 1.772 seconds.

Green finished third, Hamilton was fourth and series leader Kyle Busch was fifth.
