A.J. Hawk and the Ohio State defense stuffed Iowa's running game and kept Hawkeyes quarterback Drew Tate on the run all day. Meantime, Ohio State quarterback Troy Smith accounted for four touchdowns in the eighth-ranked Buckeyes' 31-6 victory over visiting No. 21 Iowa yesterday.

"The key was when they started out trying to run the ball and we were able to stop them," Ohio State defensive coordinator Jim Heacock said. "Once that happened, that gave us some flexibility to turn those guys loose."

Iowa (2-2, 0-1 Big Ten) finished with 18 rushes for minus-nine yards as Hawk and Mike Kudla each was credited with 11/2 sacks for 15 yards in losses. The Buckeyes constantly harassed Tate, sacking him five times for minus 43 yards.

"I couldn't get outside," Tate said. "I couldn't do anything."

The Hawkeyes, averaging 428 yards per game, mustered just 70 through the first three quarters and ended up with 137. They were forced to punt on their first seven possessions, running one play in Ohio State territory -- and by that time the Buckeyes were in control with a 24-0 lead.

* WISCONSIN 23, MICHIGAN 20: They don't need much of an excuse to throw a party at Camp Randall Stadium, but a twilight game with the 14th-ranked Wolverines was better than most.

The unranked Badgers (3-0) didn't disappoint the 83,022 revelers with a 17-point fourth-quarter rally that culminated in a quarterback draw by John Stocco for a four-yard touchdown with 24 seconds to play.

"It was a great win for us," Stocco said. "That was a good team. The guys did a great job up front. I'll do anything I can to help this team."

The Badgers stormed the field after their first win over the Wolverines (2-2, 0-1) since 1994.

It was the second loss in Michigan's last 38 conference openers. Both were to Wisconsin -- the other came in 1981.

* NOTRE DAME 36, WASHINGTON 17: Charlie Weis led the Fighting Irish to the same kind of lopsided romp over the Huskies that Tyrone Willingham did a year ago, before he was fired as Notre Dame's coach.

The 16th-ranked Irish (3-1) led 29-3 in the second half and cruised to the win over host Washington (1-3).

"If you look at five plays, we get those plays, we win," Willingham said of a goal-line fumble, end-zone interception and other mistakes that went against Washington. But he quickly added, "It won't be our coaching style to be into moral victories."

Notre Dame sophomore halfback Darius Walker rushed for a career-high 128 yards. He is the first back in school history to rush for more than 100 yards in each of the first four games.

Notre Dame fired Willingham in the third year of a five-year contract after a 6-5 regular season finish last year.

Weis facetiously dubbed this game "The Ty Bowl" because of all the attention on Willingham. Weis and Willingham shook hands before the game. At the end, Notre Dame players swarmed around Willingham to wish him well.

* SOUTHERN CALIFORNIA 45, OREGON 13: Matt Leinart threw three touchdown passes for the top-ranked Trojans on the road.

Overall, the Trojans (3-0, 1-0 Pacific-10) extended their winning streak to 25 games as they scored the final 45 points against the Ducks.

The winning streak ties the school and conference records they set from 1931 to '33.

Kellen Clemens threw a 37-yard touchdown pass and Paul Martinez kicked two field goals as Oregon (3-1, 0-1) took a 13-0 second-quarter lead.

* ALABAMA 24, ARKANSAS 13: It was supposed to be a draw play, but the Crimson Tide's Brodie Croyle saw wide receiver D.J. Hall standing by himself and changed his mind.

Hall slipped into the end zone with no defender near him and caught a five-yard touchdown pass from Croyle in the final minutes for No. 20 Alabama at home.

"I tried not to get too excited and give it away," said Hall, who also had a 43-yard touchdown catch. "I looked at Brodie and gave him a little signal. He looked at me and just nodded his head."

Said Alabama Coach Mike Shula, "We had a play called that probably wouldn't have worked."

Alabama (4-0, 2-0 Southeastern Conference) has its first 4-0 start since 1996.

The Razorbacks (1-3, 0-2) hardly resembled the team that gave up 70 points and 736 yards to No. 1 Southern California and lost to Vanderbilt earlier this year.

* MIAMI 23, COLORADO 3: Kyle Wright was drilled on Miami's first play of the game and lost a toenail on his lone touchdown pass.

Other than that, he came away unscathed and victorious in his first Orange Bowl start for the No. 12 Hurricanes.

Wright completed 20 of 39 passes for Miami (2-1) and wasn't sacked after being sacked 14 times in the first two games.

Only Mason Crosby's 58-yard field goal with 11:57 left kept the Buffaloes (2-1) from being shut out for the first time since a 7-0 loss at Nebraska in 1988.

Colorado got 120 of its 331 yards in the fourth quarter with the game decided, plus was penalized 16 times for 104 yards.

"We shot ourselves in the foot too many times," said Colorado Coach Gary Barnett. "Miami's a good physical team and they have great speed, but I thought we matched up decently."

The kickoff temperature was 86 degrees, with 70 percent humidity making it feel like 95. Conditions were quite difficult and unusual for Colorado; they're already making snow at a resort 56 miles from the Buffs' campus.

* MICHIGAN STATE 61, ILLINOIS 14: Drew Stanton set a school record with five touchdown passes and the 17th-ranked Spartans scored on six of eight first-half possessions in Champaign, Ill.

Michigan State (4-0, 1-0 Big Ten), ranked No. 4 in offense, rolled up 705 yards against the Illini (2-2, 0-1).

Stanton tied the school record, held by seven others, by halftime and broke it early in the second half. The 61 points were the most scored by the Spartans since they scored 76 against Northwestern in 1989.

* FLORIDA 49, KENTUCKY 28: In Lexington, Ky., Chris Leak threw four touchdown passes and DeShawn Wynn scored four touchdowns as the Gators got their offense rolling.

After a blocked punt led to an early Wildcats touchdown, No. 5 Florida (4-0, 2-0 SEC) scored on seven straight possessions. Wynn became the first player in Florida history to record two four-touchdown games.

Florida's win was its 19th straight over the Wildcats (1-3, 0-1). That run has included lopsided results such as 73-17, 42-7, 65-0 and 44-10.

* GEORGIA 23, MISSISSIPPI STATE 10: D.J. Shockley threw two touchdown passes and Brandon Coutu kicked three field goals to lead the seventh-ranked Bulldogs (4-0, 2-0 SEC) to the road win.

* TEXAS TECH 63, INDIANA STATE 7: Taurean Henderson ran for 141 yards and three touchdowns for the 19th-ranked Red Raiders (3-0) at home. Texas Tech was coming off an 80-21 win over Sam Houston State; both opponents were I-AA schools.

Anthony Gonzalez (11) gives No. 8 Ohio State a lift with two touchdown catches against Iowa. The defense held the Hawkeyes to minus-nine yards rushing. "I couldn't do anything," Iowa quarterback Drew Tate said.
