The Wallabies have been left to rue squandered chances and occasional moments of laziness which coach Michael Cheika says cost them a Test match they should have won.Australias search for a maiden victory at Loftus Versfeld continues after an 18-10 Rugby Championship defeat to South Africa on Saturday (Sunday morning AEST).It was an encouraging enough display but their failure to make their dominance count on the scoreboard opened the door for the Springboks - who were held tryless - to snap a three-game losing streak.We take our points down there and we win the game, Cheika said.We worked quite well to get into situations down there, then we got in there, and we didnt get enough shape to score another two or three tries, which we really should have done.Thats some of the best footy weve played in the middle of the field this season. Maybe we wanted to score too much.It also appears to have come at a heavy cost with new No.8 Sean McMahon (ankle) sent for scans and facing a potentially lengthy spell on the sidelines.McMahon hurt his ankle in a tackle just before the half-hour mark and tried to play on after having it strapped but didnt emerge after half-time.It would have to be something pretty significant for him not to come back out for the second half, Cheika said.All of South Africas points came via recalled five-eighth Morne Steyn, who kicked four penalties, two drop goals and expertly steered his team to victory.Cheika spoke on match eve of persisting with the Australian way despite the noise around hoodoos, altitude and opposition tactics, and thats exactly what they did - just not for long enough.They established a 10-3 lead after a Bernard Foley penalty and a debut Test try in the 14th minute to Scott Sio, who crossed under the posts to cap off an impressive multi-phase play peppered with smart offloads.But the Springboks fought back and turned the match into a grind after Israel Folaus sin-binning six minutes from the break.With only Folau to beat out wide, South African vice-captain Bryan Habana kicked ahead but was clipped as he tried to move past, prompting referee Wayne Barnes to produce his yellow card.Cheika reckoned only a penalty was warranted but admitted Folaus absence cost them valuable momentum.From there, the Springboks simply rode Steyns boot to victory, with their set piece play particularly impressive in the second half as they won a string of scrum penalties.Winger Reece Hodge missed three penalty attempts, two of them opportunities to put Australia ahead.The other was an audacious early crack from approximately 64m that would have equalled the longest penalty scored in Test history.It dropped less than a metre under the crossbar.Thats the game, mate. Weve got a very young, new side ... theyll learn from those experiences, Cheika said. Dragan Bender Suns Jersey .

RIO DE JANEIRO -- The young athlete, now competing at the Rio Games, always considered herself to be a girl just like the others, a girl who loved to run. Then the governing body of track and field told her she was different, so different that her track career could be over.Marked confidential and signed best sporting regards, the letter outlined a choice for the athlete: Open herself up to a panel of medical experts who could recommend surgery or chemical treatment to reduce her testosterone levels, or stop competing.She had fallen foul of the International Association of Athletics Federations rules aimed at providing a fair playing field for women by keeping out athletes with high testosterone, a naturally occurring strength-building hormone.The IAAFs medical director at the time told track authorities in the athletes country that blood and urine tests detected testosterone levels that were abnormally high. The suspected cause, wrote Dr. Gabriel Dolle, wasnt doping but another hot-button issue likely to flare in the Rio Olympics final week: hyperandrogenism.Had the athlete not been a runner, she might never have known of her condition. It was flagged up by IAAF tests that look for banned drugs. The athlete was stunned when told that her testosterone pointed to hyperandrogenism, her then-coach told The Associated Press.She couldnt understand. It was shock, the coach said. I said, `Youre not alone. There are others.Thus started a months-long process of trips to foreign clinics for batteries of tests and potentially life-changing choices.Another athlete has become the unwilling face of this complex and sensitive issue. Caster Semenya, will race and likely win gold in the 800 meters. Believed to be hyperandrogenic, outed as physiologically different without her consent when she won the world title in 2009, the South Africans dominance has again pushed to the fore divisive questions about whether allowing women to compete with testosterone far above the female norm is fair and whether the hormones attributed performance-enhancing effects are significantly greater than other natural gifts, like height for basketball players.The AP will not name the athlete, her country or give details that could identify her. In message exchanges, the athlete told AP she is focusing on competition in Rio de Janeiro and that her story is personal and private.However, the IAAF letter and APs interview with the coach, who was intimately involved in her eventual decision to agree to testosterone-curbing treatment, shed unprecedented light on the inner workings of the process that at least 14 women have gone through since the federation introduced it in 2011.Having not witthstood a legal challenge brought by another female athlete, Indias Dutee Chand, the IAAF regulations are now on hold, suspended by the Court of Arbitration for Sport since July 2015.dddddddddddd That means hyperandrogenic women can compete in Rio without reining in their natural testosterone levels.During the IAAF process, the athlete could not compete; the coach covered her absence from races by lying that she was injured. The AP will not identify the coach to avoid identifying the athlete.The first IAAF-requested tests to determine her exact condition required a trip to anot
