While Tony Stewart may have won the Sprint Cup title at NASCAR's season finale, he certainly had his work cut out for him to go out with a bang. Not only was this Stewart's fifth win in the 10-race Chase for the Sprint Cup, but it was also his third time winning NASCAR championship, according to USA Today.

The news provider is calling the event the closest title race in NASCAR history, as Stewart battled it out with Carl Edwards. While Edwards finished second this past Sunday, Stewart was proclaimed the NASCAR champion by virtue of having the most wins. Stewart knew what he had to do in order to be proclaimed champion, and he was gearing up for it all week.

"We said all week, if we just go and win the race, we wouldn't have to worry about what [Edwards] did," he told the news provider. "If this isn't one of the greatest championship battles in history, I don't know what is."

As USA Today points out, if it wasn't enough for Stewart to take the title, he will go down in history for being the first champion in the Chase era to win five races during the title. He is also the first driver-owner to take the title in the premiere series since Alan Kulwicki did in 1992.

Stewart took his first title in 2002, joining Cale Yarborough, Darrell Waltrip, Lee Petty and David Pearson to be a three-time champion.

Still, while this was cause for celebration, the finale may have been bittersweet for Stewart's team. According to The Associated Press, Stewart's crew chief Darian Grubb said that he was not sure if he would be returning to the team. Grubb told the news provider last month that he was informed he wouldn't be coming back to the Stewart-Haas racing team in 2012, and despite the victory yesterday, it does not seem as though things will change.

"I had a lot of conversations with a lot of people, telling them please give me the courtesy of waiting until tonight to see what we can accomplish," Grubb said. "Now that we've done that, I guess we'll start talking. But I'm going to do a little celebrating first."
