All grind and no glamour, the Silver Ferns wing defence role will come under the microscope when New Zealand meet Australia in the fourth and final Constellation Cup netball Test in Invercargill on Thursday.With Kayla Cullen sidelined for three months following foot surgery, the Silver Ferns have been scrambling to fill what coach Janine Southby describes as a hugely under-rated position.I think its pretty obvious were light on the ground there at the moment, she said on Wednesday.I dont know if its the most glorious position out on the court, and its not the one that gets all the kudos.But certainly wing defence is a pivotal position - when youve got a quality wing defence, you know.Long-time centre Laura Langman, who made her debut 11 years and 140 games ago for the Silver Ferns at wing defence, has provided that quality since taking over the role in Cullens absence.Langmans speed and ability to read the game have proven invaluable, and her tenacity in marking one-on-one played an important part in New Zealands 53-51 second-Test win in Launceston.Lauras that player that can shut someone down, she does a lot of ground work and wearing down, and she came up with some great tips and intercepts in that second test, Southby said.Circle defender Anna Harrison played a cameo quarter on the wing in the third Test, but her impact is greatest at goal keep or goal defence.The New Zealanders give away significant height to Australian shooters Caitlin Bassett and Gretel Tippett, who both top 1.90m comfortably, and Southby says more work is needed up-court to slow down the feed into the rangy, mobile pair.The circle like to know where the feed is coming from, and when thats controlled, it makes their job a lot easier.For a goal keeper or goal defence, if youve got feeders coming from all over the show and spinning at you, its damn hard work.Tippett shared game time with veteran goal attack Natalie Medhurst in the first two Tests, but played all four quarters in the third and looks to be an exciting long-term prospect for Australia.The 23-year-old basketball convert has only 12 Tests to her credit, but has impressed Southby with her increasing confidence and maturity.There was a lot more determination about the way she played in the third Test, and we didnt get into her head at all.We know weve got a lot of work to do to shut her down.

Sprinter Tyson Gay failed more than one drug test this year, recording one of his positives at the U.S. championships in June, where he won the 100 and 200 metres, The Associated Press learned Friday. Earlier this month, Gay revealed he tested positive in an out-of-competition test he took May 16. Three people familiar with the case told the AP that Gay had multiple positives this year. One of those people said one positive came at nationals and the U.S. Anti-Doping Agency has notified him of that result. The people did not want their names used because the doping case against Gay is ongoing and the details have not been made public. Gays representatives did not immediately respond to attempts by the AP to reach them. The sprinter has already surrendered his spot at next months world championships. If a positive test from nationals is confirmed by his "B" sample, those results would be vacated, though its likely they would be anyway because of his May 16 positive. The May 16 test has been confirmed by a test of the "B" sample, one of the people familiar with the case said. A first-time offence for doping usually brings with it a two-year ban, though athletes who co-operate with USADA sometimes get reduced penalties. One person familiar with the case told the AP that multiple positives over a short period of time are a sign of an athlete who wasnt trying to hide anything, but simply didnt know he was taking a banned drug. Gay is co-operating with USADA. "The additional positive sample is consistent with him taking responsibility," USADA CEO Travis Tygart said. "He should be commended for that and for removing himself from world championships, which we all should appreciate. The sample was expected, as he works with us for the fair resolution based on the rules, given the fact of his case." When Gay admitted to the earlier positive in a phone interview nearly two weeks ago, he fought back tears. "I dont have a sabotage story. I dont have any lies. I dont have anything to say to make this seem like it was a mistake or it was on USADAs hands, someone playing games," he ssaid.dddddddddddd "I dont have any of those stories. I basically put my trust in someone and I was let down." Since news of his positive, media reports have linked Gay to Clayton Gibson, an anti-aging doctor based in Atlanta. In an email sent to AP, Gibson would not confirm Gay was among his patients. Gay has been the most-watched U.S. male sprinter for the past several years and has long sold himself as a clean athlete. The 30-year-old, who won the world championship in the 100, 200 and 400 relay in 2007, took part in USADAs "My Victory" program -- in which athletes volunteer for enhanced testing to prove theyre clean -- and his results never raised red flags. Until, that is, the out-of-competition test in May. Results came back positive for a banned substance, the identity of which he has not been revealed. The latest news adds to a slew of negative headlines for track. Jamaican Olympic champion, Veronica Campbell-Brown, tested positive for a banned diuretic at a meet on the island in May. A month later, Asafa Powell, the former 100 world record holder, tested positive for a stimulant at Jamaicas national championships, as did his teammate, Sherone Simpson, a three-time Olympic medallist . In a recent statement, Powell said he had "retained legal counsel" and couldnt "discuss all the details of the case." "I look forward to demonstrating to everyone that I am a clean athlete. I always have been, and I always will be," Powell said. "I look forward to donning my countrys national (colours) and as I step into the blocks at the starting line I will remain, as always, proud to be Jamaican." Gay, finally feeling healthy after years of nagging injuries, was among those expected to push Usain Bolt at worlds next month, but instead of racing in Moscow, hell be resolving his doping case. Asked on Thursday about the series of doping cases, Bolt said, "definitely, its going to set us back a little bit." He insisted he was clean. "So Im just going to continue running, using my talent and just trying to improve the sport," he said. cheap falcons jerseys cheap ravens jerseys cheap bills jerseys cheap bears jerseys cheap bengals jerseys cheap cowboys jerseys cheap lions jerseys cheap texans jerseys cheap colts jerseys cheap jaguars jerseys cheap chiefs jerseys cheap rams jerseys cheap dolphins jerseys cheap vikings jerseys cheap saints jerseys cheap giants jerseys cheap jets jerseys cheap eagles jerseys cheap steelers jerseys cheap 49ers jerseys
