EDEN PRAIRIE, Minn. -- Through their first two preseason games, the best performance from Minnesotas first-team offence has been by rookie punter Jeff Locke. The Vikings havent done much well in these exhibition games yet. Each incompletion by Christian Ponder or three-and-out series by the unit has only heightened concerns whether this team can be balanced enough to build off last years playoff appearance. Even when the wins and losses dont matter, decent showings will somewhat appease the fans, soften the skepticism of the analysts, and most importantly give the coaches and players confidence in a chemistry carry-over to the regular season. "Yeah, there would be some reason for concern if we dont do certain things that weve set out to get accomplished in this ballgame, or any ballgame," coach Leslie Frazier said on Wednesday. The Vikings are at San Francisco on Sunday, and most of the starters are expected to play into the third quarter. But before this becomes an anxiety-raising, must-thrive event, theres a critical fact to point out about the way the offence bumbled through the first two games. "I was coming off the sideline saying, Oh, my gosh, what are we doing?" wide receiver Greg Jennings said. "Like, we were struggling. And then I saw this guy on the sideline that had this 28 jersey on, and he wasnt dressed, and Im like Oh, yeah. I forgot. We dont have a big part of our offence out here that draws a lot of attention. So this week will be a lot better." Assessing a team without the leagues rushing leader and Most Valuable Player is hardly worth it, especially considering the way the Vikings revolve around their star running back Adrian Peterson. This week against the 49ers, the plan is for Peterson to be on the field. "If youre an offensive player, we definitely want to take some steps forward," Peterson said. The Vikings have averaged only 14 first downs and 276 yards over the first two games, though that includes all of the time logged by backups and long shots trying to make the team. Ponder is 6 for 14 for 68 yards and one interception. His passer rating is 28.3. So this next exhibition will be a valuable opportunity for Ponder to continue trying to establish a rhythm with Jennings, rookie Cordarrelle Patterson and the rest of his receivers. Dont expect a polished product either, Jennings said. "Kinks will never completely be ironed out," he said. "There will always be a new wrinkle that we put in that were going to be trying to perfect. Just our relationship, our chemistry, were going to try to perfect that forever." NOTES: The finalists for the punt returner role are incumbent Marcus Sherels and fellow CB Bobby Felder, according to special teams co-ordinator Mike Priefer. The Vikings have been grooming Patterson for that job, too, but theyre trying to narrow his focus for now. ... DT Sharrif Floyds minor left knee operation went fine, Frazier said, and hes expected to be ready for the first week of the regular season. ... In addition to Floyd and FB Jerome Felton, whos out for the rest of August recovering from an appendectomy, the only other significant player held out of practice Wednesday was WR Jarius Wright (concussion symptoms).

Kerber was primed to keep Germany alive in the best-of-five tie, up a break in third set, but Kvitova erased a 1-4 deficit by winning the last five games of the match to give the Czechs an insurmountable 3-0 advantage in the weekend series. Kvitova blew a trio of match points before finally prevailing in a 7-6 (7-5), 4-6, 6-4 triumph. The two-time Wimbledon champ also beat Andrea Petkovic in Saturdays opening rubber and now owns a 23-6 singles mark in Fed Cup play. It was an amazing match and Im just glad I did it, said Kvitova. It was up and down from the beginning of the match and I had to fight for every single point. Maybe I was just lucky in the end. We will celebrate now. The Czechs also won the title in 2011 and 2012, losing to Italy in last years semifinals. Germany was bidding for its first Fed Cup crown since 1992 and lost to the Czechs for the third time in as many meetings over the past five years. The Germans avoided a shutout on Sunday when the doubles team of Julia Goerges and Sabine Lisicki notched a 6-4, 6-3 win over the Czech tandem of Andrea Hlavackova and Lucie Hradecka. The second singles rubber was not played. Kerber, who lost to Lucie Safarova in Saturdays second singles rubber, held a 5-2 lead in the opening set Sundayy, but Kvitova fought back with a pair of breaks to even it at 5-5.dddddddddddd Another Kerber break gave the German the chance to serve for the set, but she couldnt close it out and the tiebreaker eventually went to the Czech with a forehand winner to close out a 76-minute first set. Kvitova then had the upper hand in the second set, breaking twice for a 3-0 lead. Kerber, though, broke twice to even it, and another break gave the German the set. In the decisive third, it was again Kerber that opened a lead at 3-0. A backhand winner in the second game gave the German a break and another backhand pass made it 4-1, but it was all Kvitova from there. After a Kvitova hold, a Kerber error in the next game gave the Czech the break she needed and she hit three straight winners in the following game to even the set at 4-4. A forehand winner put Kvitova ahead with another break and she opened a 40-15 lead in the next game. Kerber saved two straight match points, the first on a Kvitova double fault and the second with a forehand winner. She then saved a third match point before faltering on the fourth with a shot into the net, ending the marathon just three minutes shy of three hours. Im a little bit sad, but it was an unbelievable match, said Kerber. Now its over. It was still a great experience to be in the final. The Czechs deserved to win it. The fourth singles rubber was scheduled to feature Safarova and Petkovic. ' ' '
