MORGANTOWN, W.Va. -- All that strength work is paying dividends for Oklahomas bruising Samaje Perine. The 243-pound freshman almost matched his weight, rushing for 242 yards and four touchdowns to lead No. 4 Oklahoma to a 45-33 win over West Virginia in their Big 12 opener Saturday night. Perine had three TDs in the second half as Oklahoma (4-0, 1-0) pulled away from a 24-24 halftime tie. He got the bulk of the carries in place of Keith Ford, who is out for at least a week with a hairline fracture in his right fibula. Perine became the first Sooner to surpass 200 rushing yards since DeMarco Murray in 2010. Blake Bell was the last Oklahoma player to have four rushing TDs in a game against Texas in 2012. "We did a good job of hitting the holes," said Perine, who averaged 7.1 yards on 34 carries. "Coach (Bob) Stoops told me that he had confidence that I could get the job done and I just went out there and did my best." Perine was Oklahomas No. 3 back entering the season. Hes already built a reputation as a weight room beast, and his power showed against the Mountaineers. "You know about how powerful and strong he is, but he has great vision," Stoops said. "He has great stamina and is a very conditioned athlete. He works hard at his conditioning." Perine ran over two defenders and scored from 9 yards out early in the third quarter, then went up the middle for a 5-yard TD late in the quarter. His 19-yard scoring romp with 4:21 left in the game put Oklahoma ahead 45-27. "Hes tough," West Virginia linebacker Wes Tonkery said. "Hes going to be something here to watch. He does what a running back is supposed to do." Oklahoma won its eighth straight game dating to last season and its 11th road game in 12 tries. Alex Ross scored on a 100-yard kickoff return and quarterback Trevor Knight caught a 4-yard scoring pass on a trick play for the Sooners. Knight overcame a shaky start and finished 16-of-29 for 205 yards. Sterling Shepard caught six passes for 101 yards. Knight was wide open when wide receiver Durron Neal found him in the end zone after taking the ball on a double reverse in the second quarter. Clint Trickett threw for 376 yards and two touchdowns for West Virginia, (2-2, 0-1). But he was intercepted twice and lost a fumble. Trickett went 25-of-41 a week after throwing for a career-high 511 yards a week ago against Maryland. Kevin White had 10 catches for 173 yards and a score while Mario Alford caught seven passes for 101 yards and a TD. West Virginia outgained Oklahoma 513-500 but couldnt match Perines power running. Rushel Shell had a team-high 60 yards and a touchdown. "They played with more effort than we did in the second half," said West Virginia coach Dana Holgorsen. "They made good adjustments at halftime. They made a bunch of plays in the second half when the game was on the line. Youve got to give them credit." Knight had early accuracy trouble and Oklahoma punted on four of its first five possessions before finding a rhythm with a pair of 75-yard touchdown drives. Alford, who dropped a pass in the left corner of the end zone in the second quarter, caught a 30-yard pass near the same spot on West Virginias next drive that initially was ruled out of bounds. The play was overturned after a review and ruled a touchdown. Perine and Shell traded short scoring runs before Ross went the length of the field on a kickoff return. It marked the third time in four games that the Mountaineers allowed a score just before halftime. Clayton Keller Jersey . The former world No. 1 Djokovic, who is the top seed here despite being ranked No. 2, snuck past 35-year-old Czech showman Radek Stepanek in four high- quality sets, 6-4, 6-3, 6-7 (5-7), 7-6 (7-5), on Centre Court. Djokovic appeared relieved when he converted on his first match point by swatting a cross-court forehand winner that just caught the line to end an affair that featured only two service breaks.

LAKE FOREST, Ill. -- The Chicago Bears agreed Tuesday to a one-year contract with defensive lineman Israel Idonije and are bringing him back for a second stint. They also released receiver Earl Bennett and added depth at safety, agreeing to one-year deals with Craig Steltz and Danny McCray. Idonije spent last season with Detroit after playing his first nine for Chicago. He had just 11 tackles and a half-sack with the Lions, but played some of the best ball of his career toward the end of his time with the Bears. He had 20 1/2 sacks over his last three seasons with Chicago. At 33, he doesnt give the Bears the youth theyre seeking. But with his ability to play end or tackle, he does provide the versatility theyre looking for as they revamp a struggling defence. A third-round draft pick out of Vanderbilt in 2008, Bennett had 185 catches for 2,277 yards and 12 touchdowns..dddddddddddd He was a favourite target of Jay Cutler, his college teammate, but he also has a history of concussions. With Bennett gone, Marquess Wilson becomes the favourite for the third receiver spot behind stars Brandon Marshall and Alshon Jeffery. Steltz, a fourth-round draft pick by the Bears in 2008, made one start last season and had one pass break-up along with 14 tackles and 14 special teams tackles. McCray was mainly a special teams contributor during his four seasons with Dallas. He had eight defensive and eight special teams tackles last season. The Bears have been busy of late, releasing defensive end Julius Peppers and bringing back cornerback Charles Tillman on a one-year deal. They have two new ends in Willie Young and Lamarr Houston, and theyve also added Ryan Mundy and M.D. Jennings to the mix at safety. ' ' '
