LAS VEGAS (AP) -- Oddsmakers in Las Vegas say Duke is the 7-to-5 favorite among the Final Four to win the NCAA title while Michigan State is a longshot despite its trip to the finals last year. Duke is rated a 2 and a-half point favorite to beat West Virginia in the semifinals on Saturday night.

The Las Vegas-based firm that recommends betting lines to 90 percent of sports books in Nevada says Butler has a 5-to-2 chance of winning the title and put West Virginia's chances at 2-to-1 and Michigan State's at 17-to-5.

The firm says Butler is favored by 1.5 points in its game against Michigan State. Butler owns the nation's longest winning streak, now 24 straight.
