While there may not be a big three in NASCAR as of yet this season, two long-time rivals are fighting for position in the standings.
Brad Keselowski got his second win of the season at Martinsville on Sunday, ending Kyle Busch's two-race winning streak, and as NASCAR's schedule shifts to Texas Motor Speedway and the O'Reilly Auto Parts 500, there's a little battle brewing at the top of the Cup standings.
Busch and Keselowski sit first and fifth, respectively, in the standings and are tied for the most wins this season with two.

But Busch has had the hot hand as of late as he won his 201st race at the NASCAR national series on Saturday and has finished in the top three of seemingly every race, but Keselowski has quietly been very good, as well, coming into the race in Fort Worth.
Busch won last year's spring race so he will likely be favored to win, but Keselowski has five top-6 finishes in his last nine races at the track.
These two drivers have an interesting past and, if either gets the leg up on the other, a war of words may be in the cards very soon, which is always fun to watch.
