Ohio State, Wisconsin roll to Big Ten victories WEST LAFAYETTE, Ind. -- Doran Grant picked off Purdue's first pass, returning it for a touchdown, and Braxton Miller threw for 233 yards and four touchdowns Saturday as No. 4 Ohio State extended the nation's longest winning streak to 21 with a 56-0 rout at Purdue. The Buckeyes (9-0, 5-0 Big Ten) have not lost in 22 months. Coach Urban Meyer also won his 22nd straight game, tying a personal best established at Florida. Ohio State scored the most points and produced the most lopsided scoring margin in the 56-game history of this series. Both topped the marks set in Ohio State's 49-0 victory in 2010. Gray's interception helped the Buckeyes take a 28-0 lead after one quarter, and they extended it to 42-0 at the half. 14 South Carolina 34, Mississippi State 16 COLUMBIA, S.C. -- Connor Shaw threw for four touchdowns, Mike Davis ran for 128 yards to move past 1,000 yards this season and No. 14 South Carolina tied a school record with its 15th straight home victory, 34-16 over Mississippi State. Shaw matched his personal best for TD throws after missing two days of practice with a virus. Davis, the SEC's leading rusher, had his seventh game reaching the century mark and became the team's first 1,000-yard rusher since Marcus Lattimore gained 1,197 yards his freshman season three years ago. South Carolina (7-2, 5-2 Southeastern Conference) won its seventh in row over the Bulldogs (4-4, 1-3) and tied the record for consecutive victories at Wlliams-Brice Stadium, equaling the mark set from 1978-80. The Gamecocks will get the chance to break the record in two weeks when they close league play at home against Florida. 21 Northern Illinois 63, Massachusetts 19 FOXBOROUGH, Mass. -- Jordan Lynch ran for 119 yards and four touchdowns and threw for another in just over a half to lead No. 21 Northern Illinois to a 63-19 victory over Massachusetts. The Huskies (9-0, 5-0 Mid-American Conference) scored touchdowns on their first five possessions and six of their seven drives in the first half. Cameron Stingily rushed for 58 yards and a touchdown, and Tommylee Lewis also ran one in for Northern Illinois. Lynch, who leads all active FBS players in rushing yards, also completed 10 of 14 passes for 160 yards and threw for at least one touchdown for the 22nd consecutive game. He played one series in the third quarter. 22 Wisconsin 28, Iowa 9 IOWA CITY, Iowa -- James White ran for 132 yards and a pair of late touchdowns as 22nd-ranked Wisconsin overwhelmed Iowa, 28-9, for its third straight win. Joel Stave added two touchdown passes for the Badgers (6-2, 4-1 Big Ten), who are bowl eligible for the 12th year in a row. Wisconsin's Pat Muldoon intercepted Iowa backup C.J. Beathard at the Hawkeyes 25-yard line with 7:43 left, setting up an 11-yard TD run by White. White added a 2-yard touchdown with 1:35 left for the Badgers, who won despite a season-low 62 yards rushing from Melvin Gordon. Hawkeyes quarterback Jake Rudock had 109 yards passing for the Hawkeyes (5-4, 2-3) before leaving the game in the third quarter with an apparent left leg injury. Air Force 42, Army 28 AIR FORCE ACADEMY, Colo. -- Anthony LaCoste rushed for a career-high 263 yards and scored three touchdowns, helping Air Force snap a seven-game skid by holding off Army, 42-28. LaCoste finished with the second-most yards rushing for a program that's known for its ground game, just shy of Chad Hall's school-record 275 yards against Army in 2007. The elusive LaCoste had TD runs of 73 and 78 yards, along with a 1-yard burst. In an injury-filled season that's spiraled downward for Air Force (2-7), this win over a fellow service academy eases some of the sting. It was a costly loss for the Black Knights (3-6) in their quest for the Commander in Chief's Trophy. Angel Santiago scored three touchdowns on a sore ankle and Terry Baggett had 121 yards rushing and a score for Army, which was trying to beat Air Force for a second-straight season. Boston College 34, Virginia Tech 27 BOSTON -- Linebacker Kevin Pierre-Lewis had a 33-yard interception return for a touchdown midway into the fourth quarter and Andre Williams ran for a pair of scores, lifting Boston College to a 34-27 win over Virginia Tech on Saturday afternoon. Williams carried 33 times for 166 yards and Chase Rettig completed 11 of 14 passes for 93 yards and a TD for Boston College (4-4, 2-3 Atlantic Coast Conference). Virginia Tech's Logan Thomas completed 24 of 40 passes for 391 yards and two TDs, but was picked off twice and fumbled twice, leading to 17 points of Boston College's points. The Hokies (6-3, 3-2 ACC) took their third lead of the game on Cody Journell's 47 field goal - his second long one of the day - 1:52 into the final quarter. But BC rallied again, tying it on Nate Freese's 43-yard field goal midway into the fourth quarter. Penn State 24, Illinois 17 STATE COLLEGE, Pa. -- Christian Hackenberg hit Kyle Carter with a 15-yard touchdown pass in overtime and Ryan Keiser sealed the win with an end zone interception, lifting Penn State over Illinois, 24-17. Bill Belton rushed for 202 yards, the first Nittany Lion (5-3, 2-2 Big Ten) to hit the 200-yard mark since Larry Johnson in 2002. Penn State's Sam Ficken kicked a 35-yard field goal with 41 seconds left in regulation, sending the game into OT. Hackenberg, who threw for 240 yards, zipped a perfect pass over the middle to Carter for the winner. Nathan Scheelhaase's first pass of OT was picked off by Keiser. With a strong second half, Scheelhaase rallied the Illini (3-5, 0-4) back from a 14-0 first-half hole to give them the lead.
