NORMAN, Okla. -- Oklahoma quarterback Baker Mayfield might have played his way back into the Heisman Trophy conversation.Baylor quarterback Seth Russell appears to be lost for the season.Mayfield passed for 300 yards and two touchdowns and ran for another score to help No. 9 Oklahoma defeat No. 25 Baylor 45-24 on Saturday in a game marred by Russells injury. A season that is fading quickly for Baylor got much worse when Russell severely dislocated his left ankle and was carted off the field with 5:48 left in the third quarter.The good news is that I think hell heal up just fine, but the bad news is that I dont think hell get back this year, Acting Baylor coach Jim Grobe said.Russell missed much of last season with a broken bone in his neck.What he went through last year, to come all the way back here to compete and just getting hurt again -- prayers out for him, backup quarterback Zach Smith said.Baylor (6-3, 3-3) had hoped to bounce back after last weeks 62-22 loss to TCU. Instead, the Bears are on their first 3-game losing streak since the middle of the 2012 season. Russell passed for 148 yards and ran for 70 before getting injured, but he threw two interceptions and lost a fumble.Mayfield got off to a rough start this season in losses to Houston and Ohio State, but he has bounced back and led the Sooners to seven straight wins. Oklahoma coach Bob Stoops said Mayfield is playing better than a year ago, when he finished fourth in the Heisman balloting. He said Mayfield has improved as he has become more comfortable with offensive coordinator Lincoln Rileys system and receiver Dede Westbrook. Mayfield has 26 touchdown passes and just five interceptions in league play.Why wouldnt you expect him with another year to be better, Stoops said. Do we expect? Yes, we do. And watching him from a year ago, having a full year under his belt with coach Riley and these other receivers, and the emergence of Dede -- yes, we expect him to be looking like this.The Sooners won their 15th straight in Big 12 play. Joe Mixon had 187 yards from scrimmage and Samaje Perine ran for 100 yards and two touchdowns after missing three games with a pulled muscle in his right leg for Oklahoma (8-2, 7-0 Big 12, No. 11 CFP).THE TAKEAWAYBaylor: The Bears collapse began with a loss to Texas, got much worse against TCU, and now, things look bleak with Russell out. Smith, a freshman, stepped in to complete 6 of 15 passes for 144 yards and a touchdown Saturday.Oklahoma: Oklahomas defense was solid for the third straight week after giving up 59 points and 854 yards against Texas Tech. The Sooners gave up three points against Kansas, then 24 against Iowa State the next game. Baylor gained 504 yards, but Oklahomas defense forced three critical turnovers.Linebacker Jordan Evans led the way with two sacks and two interceptions.Jordan, he has to play good in the middle of our defense for us to be successful, Oklahoma defensive coordinator Mike Stoops said. He knows that, and hes really come on when we needed it most.POLL IMPLICATIONSBaylor: The Bears school-record streak of 60 consecutive AP poll appearances, which Baylor says is the fourth-longest active streak in FBS, will likely end.Oklahoma: The Sooners, who were unranked heading into Big 12 play, could move higher in the AP Top 10 and position themselves to move into the College Football Playoff picture. Oklahoma was 12th in the AP poll at the same point last year.UP NEXTBaylor hosts Kansas State next Saturday.Oklahoma travels to West Virginia next Saturday. The game against the 11th-ranked Mountaineers (No. 16 CFP) provides the Sooners a chance to prove themselves against a high quality opponent.Always a challenge, Bob Stoops said. An exciting challenge. Theyve always got a raucous, rowdy crowd at West Virginia. Its a challenging place to go play.---More AP college football: www.collegefootball.ap.org---Follow Cliff Brunt on Twitter: http://www.twitter.com/CliffBruntAP . nfl jerseys china .

SAN DIEGO -- London is not calling for Major League Baseball next year.The players association says MLB has given up plans to play regular-season games in the English capital in 2017.Baseball commissioner Rob Manfred said in January that his staff was working hard at playing in London, and MLB officials looked at the renovated Olympic Stadium as a possible venue.There was discussion about London early on, union head Tony Clark said Monday. Unfortunately there were a number of moving pieces related to London that shortened our window in an effort to try to find common ground on that happening, and we werent able to get it done in time.Clark also was noncommittal about having players on 25-man active rosters made available for the 2020 Olympics, which will be held in Tokyo from July 24 to Aug. 9. The International Olympic Committee executive board voted last monthh to support a six-nation tournament that year in both baseball and womens softball, and the full IOC is to vote in August.dddddddddddd.Baseball became a medal sport for the 1992 Barcelona Olympics but was dropped for the 2012 London Games and wont be played this year in Rio de Janeiro. In 2008, only those not on 25-man big league rosters as of late June were allowed to compete; the U.S. team included Jake Arrieta and Stephen Strasburg -- both All-Stars this year.Is there an appreciation for the value of having baseball in the Olympics? Yes, there is, Clark said. Is there an appreciation for the season and how or if it could work with our active players? Yeah, theres a conversation, but we run into the same roadblocks we always have. ' ' '
