HARRISONBURG, Va. (AP) _ Curtis Keaton rushed for his third-straight 200-yard game Saturday and scored the game's only touchdown on an 80-yard third-quarter run as James Madison, ranked 10th in Division I-AA, beat 16th-ranked South Florida 13-3.

Keaton, a West Virginia transfer who has become one of Division I-AA's most dominant players, had 210 yards on 34 carries for the Dukes (7-1). The only score for South Florida (6-3) came on a Tony Umholtz field goal early in the second quarter.

The Dukes, picked to finish 10th in the 11-team Atlantic 10 Conference, won their seventh straight after a season-opening loss to Virginia Tech.

Neither team managed 100 yards passing, but James Madison won it with dominating rushing. In addition to Keaton's 210 yards, freshman walk-on quarterback Mike Connelly rushed for 36 yards on eight carries.

Keaton, who ran for 237 yards and five touchdowns last week against Connecticut, set James Madison's single-season touchdown record.
