WILLIAMSBURG, Va. (AP) _ Curtis Keaton rushed for 207 yards and three touchdowns and James Madison made the most of four William & Mary turnovers Saturday to beat the Tribe 30-20 and stay undefeated in Atlantic 10 play.

Keaton rushed for a 67-yard score on the first play of the second half to give the Dukes (5-1, 5-0) a 17-7 lead, and sealed the win with a 30-yard score with 1:09 remaining in the game.

William & Mary had 386 yards of total offense, while the Dukes managed just 245. But the Tribe helped JMU, ranked 14th in this week's Division I-AA poll, to a 10-7 halftime lead with four costly first-half turnovers.

Redshirt freshman David Corley threw for 259 yards for the Tribe (2-4, 2-2).

The Dukes built a 24-7 lead on Keaton's second score, an 8-yard run with 9:20 remaining in the third quarter.

William and Mary cut the lead to 24-20 after Corley capped a 12-play 80-yard drive with a 1-yard run and Brett Sterba kicked two field goals.

The second field goal was a 20-yarder with 6:44 remaining, after William & Mary coach Jimmye Laycock elected to kick on fourth and goal at the JMU 2.

William & Mary got the ball back, but was forced to punt, and Keaton soon ran for his third touchdown.
