ESPN Sprint Cup

What can we expect as the NASCAR Sprint Cup Series turns to Dover International Speedway? ESPN Research offers five things to know about the Autism Speaks 400:

ONE

Kyle Busch won the spring race at Dover last season, becoming the 12th different driver in as many races to win the event. Busch won the race in his seventh career start at the track.

TWO

Greg Biffle won the fall Cup race at Dover last season, earning his second career win at the track. Biffle continued the streak of Roush Fenway Racing drivers winning at least one race at Dover in each of the past five seasons.

THREE

David Reutimann takes to the track Sunday as a Cup winner for the first time in his career after winning Monday at Charlotte. Reutimann is the second first-time Cup winner this season; Brad Keselowski won at Talladega. The last time a first-time Cup winner won his next start was in 1964 when the late Billy Wade scored all four of his career wins in consecutive races. Overall, there have been four first-time winners to win their next start.

FOUR

After winning the fall race at Dover last season, Kyle Busch has won at least one race at the track in each of NASCAR's three national series: Cup, Nationwide and Trucks. He is one of only five drivers ever to accomplish the feat.

FIVE

The completion of the Dover race will mark the halfway point to the Chase for the Cup -- 13 down, 13 to go. Given the way drivers keep moving in and out of the Chase standings, there are many drivers still in contention. Positions 8-14 are separated by fewer than 100 points.
