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.

A game that appeared to be a mismatch statistically stayed close until the second half, when Ball State pulled away.

McQuale Lewis had two 1-yard touchdowns in the second half and finished with 165 yards, one shy of his career high. He caught two passes for 51 yards.

The Cardinals lead the conference in offense and defense. With their exquisite balance, they’ve won every game by double digits. Nobody has been able to keep up as the points pile up.
