Tony Stewart’s already short list of winless tracks has dwindled to two, as the three-time champion checked Las Vegas Motor Speedway off the list with a dominant performance that put his career wins total to 45. Now, Stewart remains winless at only Darlington Raceway and Kentucky Speedway.

But the back story of yesterday’s race was Steve Addington, whose tenure as Stewart’s crew chief is now three races old. Addington joined the team for the 2012 season, sliding into an organization that had won the NASCAR Sprint Cup Series championship just a few months ago.

Sunday’s win was his first at Stewart-Haas Racing, and 17th overall in the NASCAR Sprint Cup Series. Addington’s first 16 wins all came with a member of the Busch family driving (12 with Kyle; four with Kurt).

With the victory, Stewart has now won six of the last 13 races and now sits one win behind Buck Baker for 14th on the all-time series wins list.
