Kevin Harvick is right where he usually is at the Coca-Cola 600 — on top and seeking even more success.

The defending Sprint Cup champion leads the points race heading into NASCAR's longest event at Charlotte Motor Speedway on Sunday night. He has already won twice, marking the fourth time in the past five seasons Harvick will leave May with multiple victories.

Harvick is trying for his third Coca-Cola 600 win since 2011.

Harvick says early-season victories ended concerns about qualifying for the NASCAR's 10-race playoffs, and give clever teams the chance to find that extra uumph they'll need for a championship run.

Harvick has finished one or two in eight of 11 races this season.
