TUCSON, Ariz. -- Quarterback Matt Scott had 349 total offensive yards over just three quarters as No. 24 Arizona lived up to its newly ranked status in a 56-0 win over South Carolina State before 43,919 fans at Arizona Stadium. Scott completed 30 of 36 passes for 288 yards and threw for three touchdowns while rushing for another in the Wildcats' blowout win of the FCS school, which rushed for only 65 yards and only twice drove the ball into Arizona territory. Dating back to the final two games of last season, Arizona (3-0) has won five consecutive games for the first time since 1998. The shutout was Arizona's first since 2008, when the Wildcats beat Idaho 70-0. South Carolina State (1-2) will play another potentially difficult road game next week at Texas A&M. The Wildcats coasted so easily that Scott and most of the starters were taken out in the fourth quarter, yet Arizona scored on the first drive of the period to go ahead 49-0 on a 17-yard pass from B.J. Denker to Sean Willet. It was the first career TD pass by Denker, a junior college transfer from Cerritos College who was making his Arizona debut, and the first career TD reception by Willet. Denker subsequently threw a 31-yard pass to Patrick Onwuasor to set up another touchdown, a 4-yard run by Jared Baker that made it 56-0. South Carolina State quarterback Richard Cue completed 12 of 25 passes for 89 yards and was intercepted once. Junior Tyler McDonald led the Bulldogs in receiving with four catches for 47 yards. Scott finished a strong first half by leading the Wildcats' final scoring drive before halftime. He completed three passes for 18 yards and rushed for a 10-yard touchdown that gave the Wildcats a 28-0 lead. Scott finished the half with 236 yards, completing 20 of 26 passes for 175 yards and carrying the ball nine times for another 61 yards. Running back Ka'Deem Carey was the Wildcats' leading rusher in the first half, with 71 yards and one touchdown on 13 carries. The Wildcats started playing like they were expected to early in the second half. They took advantage of an interference call on a punt return to take the ball on their 47 and punch it in for a touchdown seven plays later, going ahead 14-0 when Taimi Tutogi caught a 14-yard touchdown pass up the middle. Arizona scored another touchdown on its next drive of the second half, going 72 yards over 12 plays. The Wildcats made it 21-0 when Carey finished the drive by rushing to the right side for a 7-yard touchdown. While Arizona scored easily on its first drive of the game, the Wildcats had a spell of sloppiness. Richard Morrison fumbled after taking a pass from Scott at midfield, and kicker John Bonano later missed a 15-yard field goal attempt with three minutes left in the quarter. Bonano had just been named the Pac-12's special teams player of the week after nailing all three of his field-goal tries last week in Arizona's 59-38 win over Oklahoma State. On their first drive, the Wildcats rattled off a nine-play, 75-yard drive in less than three minutes, scoring on a 15-yard touchdown pass from Scott to Morrison. NOTES: Scott entered Saturday tied for the top spot nationally in total offense with 836 yards. ... Carey scored five touchdowns in Arizona's first two games, tying him for third nationally. ... The Wildcats are ranked in the Associated Press Top 25 for the first time since Nov. 22, 2010. ... Arizona and South Carolina State had never played before.
