MASON, Ohio -- John Isners absence from the ATP top 20 will be brief. The 6-foot-10 American made sure of that Saturday, rallying to beat seventh-seeded Juan Martin del Potro 6-7 (4), 7-6 (9), 6-3 in a grueling Western & Southern Open semifinal. Isner, who fell from No. 20 to 22 this week, will return to the top 20 after a stimulating Cincinnati run that includes beating three straight top-10 players for the first time in his career while earning his second Masters 1000 series finals appearance and first in Cincinnati. His previous Masters 1000 final appearance was at Indian Wells in 2012. "Its awesome to be at this stage again," said Isner, who beat top-ranked Novak Djokovic in the quarterfinals and No. 8 Richard Gasquet in the second round. "Ive been playing pretty well this season, but this tournament is where Ive really started to put it all together. Im playing pretty well in all facets of the game." Isner, in his first appearance in the tournaments semifinals, had been 0-4 against the Argentine. Hell play third-seeded Rafael Nadal, who beat sixth-seeded Tomas Berdych 7-5, 7-6 (4) in the other semifinal to reach the tournament final for the first time in nine appearances. "This is one tournament that Ive never been able to play well, so its something special to play well in a place I never did in the past," said Nadal, 3-0 in his career against Isner. "Im very happy for that. I am having the right feelings on court. Im playing aggressive, and the crowd here is great." Nadal extended his personal winning streak against the Czech to 14 matches while improving his overall season record 52-3, including 14-0 on hardcourts. After winning at Montreal last week, the Spaniard will be making back-to-back appearances in hardcourt finals for the first time in his career. Hes 15-1 against top-10 players this season. Top-ranked Serena Williams also will be making her first career appearance in the events championship match after ousting defending champion Li Na, 7-5, 7-5, in the first womens semifinal. Williams, seeking her ninth title of the year, advanced when Li double-faulted on match point. Williams improved to 60-3 this season. "I really would not have predicted myself being in the finals here at all, so its definitely pretty exciting for me," said Williams, who clinched the 2013 Emirates Airline U.S. Open Series womens title with the win and can earn a $1 million bonus if she wins the U.S. Open. "Really unexpected for me, too. I came in here not playing my best, and now Im in the final. Its just almost weird." Williams will play second-seeded Victoria Azarenka in Sundays final. Azarenka beat 14th-seeded Jelena Jankovic 4-6, 6-2, 6-3 in a semifinal that featured 23 service breaks in 27 games. Isner needed 2 hours, 47 minutes to improve to 16-3 since retiring from Wimbledon in the second round because of a left knee injury. He finished off the win when del Potro sent a backhand from the baseline into the net. Despite tossing into a persistent swirling breeze and bright sunshine, both players served so effectively early that the first set included just one break point, fought off by the 22nd-ranked Isner. The 6-foot-6 Del Potro came up with a crucial mini-break on the 11th point of the tiebreaker when Isner sailed his backhand volley wide to lose the set. Del Potro broke Isner in the eighth game of the second set to put himself into position to serve for the match, but he double-faulted on match point and Isner came up with his own break to stay alive and eventually force a tiebreak that he won when del Potro sent a forehand wide to the deuce court. "I think I lost the match in the second set," del Potro said. "That was my chance to beat him. He was fighting all the time and deserved to win the third set, but I missed my chance." "I know, at that moment, that the sun on that side was pretty bad," said Isner, who can become the first American to win the tournament since Andy Roddick in 2006. "We both struggled with that for about 30 minutes." Despite the loss to Nadal, Berdych still will move up a notch in the rankings to a career-high fifth, passing Roger Federer. "That makes it probably even more special," Berdych said. Buy Nike Vapormax Online .com) - Ames, IA (SportsNetwork. Cheap Nike Vapormax Sale .

SAN DIEGO -- James Shields was on another road mound and thats a good thing for the Kansas City Royals. Then again, he really was at his home away from home. "It was nice to sleep in my own bed last night," Shields said after pitching Kansas City past the San Diego Padres 8-0 Wednesday. Shields (4-3) won at Petco Park, which isnt far from his residence in Rancho Santa Fe. "I got to play with the dog and see the kids for the first time in about a month," Shields said. "It was really nice to be around the house." Shields wasnt a welcome sight for the San Diego batters, scattering seven hits over seven innings. With Eric Hosmer driving in a season-high four runs and the Royals scoring three times in the first inning, Shields was able to win with less than his best. "I didnt think my stuff way that good today," said Shields, who threw a season-high 118 pitches. "I was all over the place, getting behind in counts a lot. It was a grind day, but sometimes you got to go out there without your good stuff and compete and that is what I did." Padres ace Andrew Cashner (2-5) didnt see the fifth inning. "Were kind of in a team-wide funk," Cashner said. The Royals are headed the opposite direction. They won their second straight game, took their first series at Petco Park and snapped a five-game losing skid since rolling into town. "That was what you call an AAGG -- an all-around good game in all phases," Kansas City manager Ned Yost said. "Shields was fantastic, the bullpen was great, our defence was solid and we had very, very good baserunning. And our offence had as good as a day as we have had against a darn good young pitcher in a long time." For a good stretch, Shields, who struck out four and walked two, has been tough on the road. Hes won four straight starts away from Kauffmann Stadium and since the start of last season is 14-4 with a 2.00 ERA. Hosmer got three hits. He finished the series going 7 for 15 with seven RBIs, a homer and a double. "The power numbers will come," Hosmer said. "Im not worried about that. Its early in the season and right now Im just doing anything to help this team win." "The biggest thing today was coming up with runners in scooring position and getting guys in," he said.dddddddddddd The Padres scuffled, not having any better luck against two relievers after Shields exited. They were shut out for a major league-high sixth time this season. San Diego has lost six of eight overall. Cashner, who lasted a season-low four innings, had trouble from the start. He threw 43 pitches in the first, hurt by a pair of errors from shortstop Everth Cabrera that led to two unearned runs. "I feel bad for my teammate, for Cashner," Cabrera said. Alcides Escobar reached when Cabrera misplayed his ground ball after Nori Aoki opened with a single. Hosmer hit a two-run single, Alex Gordon reached base two batters later when Cabrera mishandled his grounder and Danny Valencia followed with a broken-bat, RBI single. Cashner ended the inning by getting Shields to ground out with the bases loaded in a nine-pitch at-bat. "That was the best AB of the game," Hosmer said. The Padres had a chance to cut into their deficit in the second when they got three hits. But Cameron Maybin was too aggressive rounding second base on an infield single, and Escobar slid in behind from shortstop, took Hosmers throw from first base and made the tag. Padres manager Bud Black requested a review, but the call stood. It marked the first time in five appeals this season that Black had lost. The Padres tied a season high with three errors, and had a passed ball and wild pitch in allowing four unearned runs.
