J.R. Redmond ran for 157 yards and two touchdowns and was the decoy to spring Delvon Flowers on a 40-yard scoring reverse that helped No. 25 Arizona State beat visiting Texas Tech, 31-13, last night.

Redmond won the duel of touted tailbacks handily, piling up more yardage on a 56-yard scoring run 23 seconds into the second quarter than Red Raiders counterpart Ricky Williams had in the game.

Williams, the top returning rusher in the Big 12 Conference, sprained his left knee twice in the third quarter. The second time, he was carried off the field after gaining a career-low 33 yards on 13 carries and scoring on a one-yard run.

Williams's touchdown gave the Red Raiders a 7-0 lead 3 minutes 18 seconds into the game.

The Sun Devils played the last three quarters without quarterback Ryan Kealy, who sprained his right knee dropping back to pass late in the first period.

But they compensated with sophomore John Leonard -- who was 7 of 17 for 117 yards -- big defensive plays, including five sacks, and Redmond, who also had a three-yard scoring run.

Stephen Baker kicked field goals of 40, 35 and 34 yards to help deny Red Raiders Coach Spike Dykes his 77th win, which would have made him the winningest coach in school history.

SOUTHERN MISS 48, TULANE 14: In Hattiesburg, Miss., surprise starter Jeff Kelly threw four touchdown passes as the Golden Eagles ended the Green Wave's 13-game winning streak.

Kelly, No. 2 on the depth chart behind junior college transfer Cable Davis throughout the preseason, hit 13 of 19 passes for 248 yards with touchdowns to four players.

Tulane, playing its first game in four years without record-setting quarterback Shaun King, had the nation's second-longest I-A winning streak after going 12-0 last season.

The Green Wave's perfect season included the Conference USA title that Southern Miss had won in 1997 and shared during the conference's inaugural season in 1996.
