SINGAPORE -- Defending champion Agnieszka Radwanska took the final spot in the semifinals of the WTA Finals, beating Karolina Pliskova 7-5, 6-3 on Friday.Radwanska, who finished 2-1 in the round robin, will play top-seeded Angelique Kerber in Saturdays semifinals. Kerber won the Australian Open and the U.S. Open this season, and reached the Wimbledon final.I think I really have nothing to lose at the moment, especially (since) Im going to play the best player of the season, Radwanska said of the top-ranked German. Shes played incredible tennis this year.Earlier, Svetlana Kuznetsova earned first place in the White Group despite losing to Garbine Muguruza 3-6, 6-0, 6-1.Kuznetsova will next play Dominika Cibulkova, who reached the semifinals despite finishing 1-2.Pliskova offered Radwanska too many free points, making 29 unforced errors to only eight for the Pole.Radwanska initially trailed 4-2 in the first set, but she soon recovered to 4-4.I just really play my best tennis against her, Radwanska said. I can really play my game and do my things, things that I want to do on court and have a good rhythm.In the second set, Radwanska scored the final service break in the eighth game when Pliskova netted two consecutive overheads.Kuznetsova managed to win the first set against Muguruza, but looked fatigued after that.Definitely, you dont want to lose the match, said Kuznetsova, the last player to qualify for the season-ending tournament. You try to fight. Sometimes the lack of energy just wont let you do that. Cheap Sabres Jerseys . As the crowd erupted, Davis knocked the ball off the glass and back into his hands.

LAKE FOREST, Ill. -- Star receiver Alshon Jeffery was suspended Monday for four games without pay for violating the NFLs policy on performance-enhancing substances, the latest staggering blow for the reeling Chicago Bears.Jeffery posted on Twitter that he took a supplement for inflammation containing a substance banned by the league.I take full responsibility and Im deeply upset with myself for not doing the proper research on this supplement, he wrote. I want to apologize to my family, the Bears organization, my teammates, and Bears fans. I will work hard to earn back the respect and trust of the Bears nation and look forward to being back on the field.His suspension was another dose of bad news for a team that lost several players to injuries in an embarrassing 36-10 loss at Tampa Bay that left the Bears with a 2-7 record. Now, they will have to get by without arguably their best player, starting with Sundays game at the New York Giants.Obviously were very disappointed, coach John Fox said. I think hes fairly embarrassed about it, but well support him and welcome him when he gets back after serving his suspension.As if Jefferys punishment wasnt enough, it looks like the Bears will be without star right guard Kyle Long. The NFL Network reported Monday that he will miss the remainder of the season with an ankle injury.Jeffery will be eligible to be activated on Dec. 12 and play against Green Bay six days later. He leads the team with 630 yards receiving and is second with 40 catches.It (stinks) not having your top weapon on offense, tight end Zach Miller said. We have to figure out ways to be better, to do better collectively. But I dont think you really replace Alshon Jeffery that easily. Well have to do it as a group.Jeffery is playing for the $14.6 million franchise tag after he and the Bears were unable to agree to a long-term contract in the offseason. He was limited to nine games because of injuries a year ago, and now has a PED suspension hanging over him with his contract set to expire again.Fox said players found out during meetings on Monday.All teammates, I think, at the end of the day, theyre supportive, Fox said. But I know Alshons embarrassed by it and Im sure disappointed would be a good word for the rest of us.FFox mentioned a silver lining with receiver Marquess Wilson potentially returning soon from a foot injury.dddddddddddd He has been on the physically unable to perform list since training camp. But his comeback would be small consolation, particularly given the rash of injuries the Bears suffered against the Buccaneers.Long, a three-time Pro Bowl lineman, left the field on a cart with a right ankle injury. Fox indicated after the game that it might be a high ankle sprain, though he said Monday a full determination on the injury had not been made. Ted Larsen figures to take his place in the lineup, though Eric Kush is a possibility.Fox had no update on running back Jordan Howard (ankle or Achilles tendon), nose tackle Eddie Goldman (ankle) or defensive lineman Will Sutton (ankle). Right tackle Bobby Massie also suffered a concussion.The loss to Tampa Bay also raised more questions about the direction of the franchise and wiped out any good vibes the Bears had after they knocked off NFC North leader Minnesota two weeks earlier.Jay Cutler threw two interceptions and fumbled twice after leading the Bears to a victory over the Vikings in his return from a sprained right thumb. It all added up to a big reality check for a team that was as confident as any with two wins halfway through the season could be.The Bears thought they might turn the corner with key players coming back from injuries. Instead, they crashed.I still feel like were not out of it, Miller said.Mathematically, theyre not.The Bears trail Detroit and Minnesota by three games and Green Bay by two in the division. The Vikings are struggling in a big way with four straight losses. So are the Packers, who have dropped three in a row.But with Jefferys suspension, the Bears will have to get by without one of their biggest playmakers.I guess the best word I could use would be unfortunate, defensive end Akiem Hicks said. Because I look forward to seeing 17 (Jeffery) out there going up deep and catching balls and making plays. Its unfortunate and Im going to miss him.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFL ' ' '
