Olympics-Athletics-With only one Russian in Rio, U.S. eyes bumper medals haul

By Jack Stubbs RIO DE JANEIRO, Aug 11 (Reuters) - The United States is expected to run away with the athletics competition in Rio, taking podium spots often the preserve of Russians such as double pole vault gold medallist Yelena Isinbayeva and 110m hurdles world champion Sergei Shubenkov. Russia has taken second place on the athletics medals table at the last three Olympics and, as with the Soviet Union before it, has long been the United States' main challenger in track and field. But with Russia's athletics squad all but entirely excluded from the Rio Games following revelations of state-backed doping in the sport, the door is open for Team USA to build on a table-topping haul of 28 medals at London 2012. Jamaica, with its powerhouse of record-breaking sprinters, could also place second on the competition medal table for the first time, leaving Kenya, Ethiopia and Germany to battle it out for third place. U.S. athletes have already been feeling the benefits of Russia-free competition in the build up to Rio, raking in 23 medals at the World Indoor Championships in March. Their nearest competitor, Ethiopia, won five. The IAAF's Doping Review Board turned down applications from 67 Russians to compete internationally as "neutral" individuals, following a blanket ban on the country's track-and-field athletes for systematic doping. Long jumper Darya Klishina was the only one approved for Rio, having proved she was not involved in the system and subject to drug tests outside the country. Isinbayeva came third at London 2012, with Jenn Suhr of the United States claiming the gold, but as the pole vault world-record holder and champion in Beijing and Athens, she would have been a serious challenger in Rio. She and Shubenkov had their final appeals to the Court of Arbitration for Sport (CAS), sport's highest authority, rejected on Monday. A vocal critic of Russia's exclusion, which she says punishes clean athletes like herself who have never failed a doping test, Isinbayeva has said any medals won in Rio will be illegitimate. "Let all these foreign pseudo-clean sportspeople sigh with relief and win their pseudo-gold medals in our absence," she wrote on Instagram after CAS upheld the Russian team's ban in July. "They have always feared (our) strength." In the men's events, Russian hopes were resting on hurdler Shubenkov, who pulled off a shock win at the world championships in Beijing last year with a top-20 time of 12.98 seconds. "As an athlete you ... always want to compete against the best," U.S. rival Devon Allen told reporters. "The defending world champion is Russian so, as a competitor, it is disappointing because obviously I want to compete against him. "But on the other side, I don't make the rules. I just show up and compete." (Additional reporting by Andew Downie; Editing by Alison Williams)
