NEW YORK -- When Adeline Gray stepped on the wrestling mat in high school against a male competitor, she got his attention pretty quickly.She grabbed her opponent, and his eyes opened up like saucers, like `holy cow, Ive got to fight for my life, said her father, George.Gray is all business on the mat, with a 38-0 winning streak the past two years against women. She started wrestling at 6, first coached by her dad and uncle near Denver, Colorado. She grappled with the boys in youth leagues through high school. Now, the three-time world champion will attempt to win the first gold for U.S. womens wrestling on Aug. 18 in Rio.She has the ability to stay focused when the lights are on, George Gray said. She knows how to win.Gray won the majority of her high school matches against boys at 130-140 pounds. Now shes coached by Terry Steiner, a former All-American wrestler at Iowa who leads the U.S. womens national team.Womens wrestling was added at the 2004 Athens Games. When wrestling nearly got tossed out of the Olympics three years ago, increasing womens participation was among the improvements required by the IOC. Women were added to wrestling boards and female referees to the mat. Two more weight classes were added, bringing the total to six in Rio.Gray, a three-time world champion, has traveled to 22 countries for competitions in the last several years. Shes spent eight years at the U.S. Olympic training center in Colorado Springs, getting ready for the Japanese women. They won three of the four golds at the 2012 London Games, where Gray was an alternate.Here are some things to know about the 25-year-old Gray, who is ranked No. 1 at 75 kilograms (165 pounds).EARLY TRAININGShe joined her uncles wrestling club and started with tumbling and basic moves to see who had better balance. She honed her wrestling technique and competitive skills around age 12, when she developed strength and skill and put that into a complete match, she said.Gray says her mother Donna will attest that she was super-hyper as a kid. Wrestling and playing soccer with her three younger sisters helped redirect her energy.I definitely think my parents had the option to medicate me to kind of calm me down, and they chose to put me in athletics, she said. It helped me in school, it helped me in so many different areas of my life.GRAPPLING GUYSGray was 16-16 against boys while attending Bear Creek High School her freshman year on the varsity team, where teammates knew her from growing up together on the mat. Her dad said shed often trail 2-0 because the boys were faster at the takedown, but shed always either reverse or get around and then get on top. She pinned a lot of boys.Her family moved the next year and she went 20-10 at 135 pounds at Chatfield High School. Her junior year she was captain of the boys team and finished 20-7.Occasionally, there was pushback from parents at other schools. Some of these boys played the gender card, `Im not going to wrestle her, were not supposed to be hurting girls, George said. But guess what, Id see him two weeks later at a different tournament wrestling a girl because he knew he could beat that girl.While there were some forfeits, George says Adeline is where she is today because she wrestled the boys. It made her better.I had my dad in my corner the whole time, she said of the former wrestler and police officer. He really just gave me that freedom to go out there and be an athlete.OLYMPIC PREPAfter winning the junior world title at 17, Gray moved to an Olympic development program at Northern Michigan University and finished high school in Marquette, Michigan. She recently earned a business degree through DeVry University.Gray will be joined in Rio by three teammates -- Elena Pirozhkova (63 kg), Helen Maroulis (53 kg) and Hayley Augello (48 kg).The women wrestle two rounds of 3 minutes in freestyle, which allows for throws and hooking the legs. The men wrestle both Greco Roman, grappling from the waist up, and freestyle.GATOR ROLLGray is known for her arm bar and chicken wing pins and the leg lace move. That involves an arm lock around the ankles, crisscrossing them. Then a gator roll, you start turning, her dad said. If they dont, theyll pop a knee or the pain is unbelievable, so you turn. Thats two points.Gray tries to dominate the opponent early in the match. You dont want to wait around to see peoples best stuff, she said. You want to hammer them with what you have and get off the mat.GAINING GROUNDWomens wrestling is not an NCAA sport, but high school girls wrestling is gaining popularity in California, Washington, Texas, Florida and Hawaii, Gray said.Whats the difference between wrestling boys and girls?(Boys) dont have shoulders like Gumby, she said. Girls get out of pinning holds that no boy would ever be able to get out of. Boys, their shoulders are so stiff, if you get the right leverage on a shoulder, theyre going to go over and pin themselves.Kevin Durant Nets Jersey .

Reigning world champion Eve Muirhead of Scotland opened with a 12-2 rout of Winnipegs Jennifer Jones in a battle of teams bound for the 2014 Winter Olympics in Sochi.Will Greenwood believes George Ford is still in pole position to start at No 10 for England against Australia on Saturday, live on Sky Sports.Ford has been Eddie Jones first-choice fly-half for his six Tests as head coach, but the 23-year-old performed poorly with the boot during Englands 27-13 win over Wales, missing six of his seven attempts at goal. The Bath No 10 faced booing and ironic cheers from the Twickenham crowd when he managed to convert Jack Cliffords try just after half-time, resulting in calls for him to be replaced by Owen Farrell.Jones has used Farrell at inside centre and Greenwood believes the Australian will remain loyal to the side that secured Englands first Grand Slam title since 2003.I think George Ford will still be in pole position in terms of Eddie Jones, Greenwood told Sky Sports News HQ.I am a big fan of George Ford, the crowd of course will look to his kicking stats - but dont worry about them. Farrell will step up and nail five out of six, but Jones is trying to find that balance and fluidity to his backline that is not quite there. Luther Burrell is getting back to his best Although they scored five tries against Wales, it was a bit clunky and needs a bit of WD40. If Jones does not go with Ford, then he will have Farrell at No 10 and move Luther Burrell straight into the inside centre slot.But I dont envisage many changes - Jones is not afraid of pulling rabbits out of hats but he is enormously loyal to the players who do him proud and pull off the big wins. Englands new coach Glen Ella is impressed with the team as they prepare for the tour of Australia You suspect that the team that won the Grand Slam in Paris may just get first dibs in Brisbane against those pesky Australians.Confidence boostGreenwood believes England will be the most confident side out of the three home nations heading to the southern hemisphere this summer with Wales travelling to New Zealand and Ireland to South Africa. Its a massive Saturday for most of the home nations sides, said Greenwood.First up we will be in Auckland - I will have Sean Fitzpatrick on one side and Scott Quinnell on the other and Wales will be trying to do something that they have never ever done before - which is win in new Zealand. Wales have only beaten New Zealand once and that was way bback in 1953.dddddddddddd.Straight after that, we head over to Brisbane where we could see another first. England may have won in Australia before but never in Brisbane - their record is played four and lost four. Then in the afternoon, Ireland take on South Africa.Go back five or six months to the World Cup where New Zealand won it, Australia came second and South Africa came third so it is an enormous challenge. In the meantime, they have had a long break while the home nations have fought and scrapped amongst themselves to be top dog. England came out on top and are Grand Slam champions but the acid test, the barometer of how far all these sides have come comes on Saturday.He added: England are probably the most confident of all three heading to Australia.Wallaby coach Michael Cheika has not called upon the likes of Matt Giteau, Dre Mitchell, Matt Toomua and Adam Ashley Cooper. So four to five of their World Cup final back-line are not available.I would not say that an unbeaten England under Eddie Jones tenure will be over confident, but they will be confident starting the series well at an amazing stadium.Building momentum Highlights of Englands 27-13 win over Wales at Twickenham Jones has admitted Englands hopes of completing a series victory over Australia hinge on the outcome of that first Test at the Suncorp Stadium, and Greenwood agrees.If you go 1-0 down, you can still come back and win the series but its like Andy Murray going down to Novak Djokovic at the French Open - once you go down two sets to one, then you know you have to win the next two against a guy who hardly loses one set, never mind two.Australia very rarely lose two Tests on the spin at home so if you lose the first Test, then you are snookered a fraction. If you get off to a good start, then you are in good shape to go on and nail the series.It should be a cracking series and a good chance to see if the gaping chasm between the southern hemisphere and northern hemisphere has got bigger, or are we a little bit closer.Watch New Zealand v Wales, 8am, Sat, Sky Sports 1 HD followed by Australia v England, 11am, Sat, Sky Sports 1 HD and South Africa v Ireland 3.30pm, Sat, Sky Sports 1 HD.
