DAYTONA BEACH, Fla. — When Boston Red Sox majority owner John Henry and NASCAR team owner Jack Roush began talking about a partnership more than three years ago, both teams were notorious for falling painfully short of winning championships.

Now they've both got titles and plan on winning plenty more together under a new banner: Roush Fenway Racing.

"I think owners get into sports for one reason: You want to win championships," Henry said Wednesday in an interview with The Associated Press. "That's something that we've tried to do, and we've successfully done it on our own. That's the primary reason. I think that we can help Jack's vision of what he wants to try to accomplish over the next 10 years, and we'll win championships."
