RICHMOND, Va. — Denny Hamlin won the Federated Auto Parts 400 on Saturday night, giving him his first victory at his home track of Richmond International Raceway in six years. Hamlin pulled away on the restart for the final two laps of overtime that followed the last of a track-record 16 cautions.

He held off Kyle Larson for the victory. Martin Truex Jr., who led for a high of 193 laps, was third, with Brad Keselowski fourth and Kevin Harvick fifth.

Hamlin led the first 50 laps before Truex moved to the point and led 134 laps by the halfway (200-lap) mark. Truex led for long stretches by four to five seconds.

Laps 201-300 featured more dominance by Truex and Hamlin, who led 41 laps each during that span. Hamlin dominated the point from the 300-lap mark, leading 86 laps down the stretch.

The race finalized the field for the Chase, the NASCAR Sprint Cup Series' 10-race playoff that begins at Chicagoland next Sunday.

A number of Chase spots had been decided coming into Richmond. Already qualified were four-time winners Brad Keselowski and Kyle Busch, two-time winners Kevin Harvick, Carl Edwards, Denny Hamlin, Martin Truex Jr. and Matt Kenseth, and one-time winners Joey Logano, Kurt Busch, Kyle Larson and Tony Stewart.

Chase Elliott and Austin Dillon started Saturday as virtually certain locks to make the Chase, and that did not change during the 300-mile race on the three-quarter-mile oval at RIR. Two Chase spots were decided in the final regular-season race.

Chris Buescher and Jamie McMurray began the night in commanding positions for those berths, and closed the deal easily. Buescher, with a victory in hand, needed to remain ahead of David Ragan for 30th place to qualify for the Chase. Buescher's ticket to the Chase was punched when Ragan was sidelined by a wreck with 37 laps to go.

That wreck, which included Stewart, also sidelined Ryan Newman and killed his already faint Chase hopes. Newman blamed the wreck on Stewart, his former boss at Stewart-Haas Racing, calling him “bipolar” in a TV interview.

McMurray finished seventh and secured the final Chase berth.
