OXFORD, Ohio | For the first time in its history, Ball State is a perfect 10.

Nate Davis threw for a touchdown and ran for another in a quick-strike offense, and the 14th-ranked Cardinals stayed unbeaten by wearing down the Miami RedHawks for a 31-16 victory Tuesday night.

Ball State improved to 10-0 for the first time, with six of the wins in the Mid-American Conference. The Cardinals matched their school record for victories -- they went 10-1 in 1978. Their only perfect season came in 1949, when they won all eight games.

Miami (2-8, 1-5) hasn't beaten a ranked team since Nov. 4, 2003, when Ben Roethlisberger led the RedHawks to an upset of Bowling Green.
