BEIJING -- Rafael Nadal will supplant Novak Djokovic atop the rankings after advancing to the final of the China Open on Saturday when Tomas Berdych of the Czech Republic retired with a back injury. The Spaniard was a break up at 4-2 in the opening set of their semifinal when Berdych retired soon after taking an injury timeout. Nadal could face Djokovic on Sunday, as the Serb played Richard Gasquet of France in the other semifinal later Saturday. Nadal, who improved to 27-0 on hard courts this season, will return to the top ranking for the first time since July 2011. Djokovic has been No. 1 for 101 weeks. "The personal satisfaction is not because I am No. 1 today, its because (of) all the work (I put in) to be where I am today," Nadal said. "I dont feel (like) a better player now than five hours ago, and I wont go to bed tonight feeling that I am the best player in the world--thats something Ive never thought." In the womens draw, top-ranked Serena Williams and Jelena Jankovic of Serbia advanced to the final with contrasting wins. Serena earned a straight-forward 6-2, 6-2 victory over Agnieszka Radwanska of Poland while Jankovic rallied for a 6-7 (7), 6-1, 6-1 win over Petra Kvitova of the Czech Republic. Nadal had been assured of reclaiming the top spot if he reached the final in Beijing or Djokovic failed to defend his title. Nadal, the reigning French Open and U.S. Open champion, has had a dominant year since returning in February from a seven-month layoff due to a left knee injury. He has won 10 titles and reached 12 finals overall, compiling an ATP Tour-best record of 65-3 on the season. He hasnt lost a match since falling in the opening round at Wimbledon to 135th-ranked Steve Darcis of Belgium in June, his only blip this year. "(This is) a great year, one of the best years of my career without any doubt," Nadal said. "Sure is special (to) be back to the top position of the rankings after more than a half year without playing tennis." John Paxson Jersey .

New York Mets manager Terry Collins is now one of them. Collins got his first look at the Pittsburgh Pirates rookie right fielder Thursday night and came away impressed. "Hes got a lot of tools, a lot of skills," Collins said. "I watched him in batting practice and you see he had big power, then he showed it in the game. Hes very impressive." The hot-hitting Polanco homered and drove in four runs, and resurgent right-hander Vance Worley pitched seven stingy innings to lead the Pirates past the Mets 5-2 for their fifth win in six games. Polanco drove in the games first run with a groundout in the first inning, then sent a three-run homer into the right-field stands off Daisuke Matsuzaka in the fifth to put the Pirates ahead 5-1. The right fielder went 2 for 3 with a walk and is hitting .338 in 16 games since being called up from Triple-A Indianapolis on June 10. The Pirates are 10-6 since Polanco arrived, pushing them one game above .500 at 40-39. "Hes a talented young man, so Im humble to have him on the club and the opportunity to write his name in the lineup," Pirates manager Clint Hurdle said. "Its a good time for him to be included on our club and hes obviously been making a difference since hes been up here." Worley (2-0) scattered seven hits, walked two and struck out three. He has given up four runs in 20 2-3 innings over three starts since coming up from Indianapolis on June 15. He was 1-5 with a 7.21 ERA in 10 starts for Minnesota last season. Hurdle was particularly impressed that Worley pitched so effectively while struggling with his command. Worley had walked only five batters in 58 2-3 innings between Pittsburgh and Indianapolis prior to Thursday. "It was a very solid body of work, a very professional effort," Hurdle said. "Hell be the first one to tell you he wasnt as sharp as hed been previously. You saw a man go out tthere and have to wrestle a little bit and maintain composure, mound presence, and just pound the zone.dddddddddddd" Matsuzaka (3-2) allowed five runs and five hits in six innings with four walks and four strikeouts. Lucas Duda hit his team-high 12th home run for the Mets. New York cut it to 5-2 on back-to-back doubles by Daniel Murphy and David Wright in the eighth, but Mark Melancon pitched a perfect ninth for his 14th save. Polancos home run came on a full-count pitch with one out after Pedro Alvarez hit the first of his three singles and Worley also singled. Polanco sounded a little like famous Notre Dame football coach Knute Rockne when he talked about his approach at the plate in that situation. "I just fight, fight, fight, swing, swing and try to make contact," Polanco said. "I stayed with my approach and I hit it." Polanco hit a slider after Mets catcher Travis dArnaud had called for a changeup. "I shook off dArnaud and that ended up being a big mistake," Matsuzaka said through a translator. "I apologize to him about that." NOTES: New York activated CF Juan Lagares (ribcage) from the 15-day disabled list before the game. ...
