In January 2000, Federer competed for the first time in the Australian Open, losing to 49th ranked Arnaud Clément of France in the third round. He then equaled this achievement in his very first US Open, losing in the third round to 12th ranked Juan Carlos Ferrero of Spain. After reaching the semi-finals at the 2000 Sydney Olympics, Federer reached his first ATP final in Marseille, where he lost to compatriot Marc Rosset, and was also the runner-up in his home tournament at Basel. He did, however, win the Harry Hopman Cup in Australia defeating Jan-Michael Gambill in the final in straight sets. Even though he failed to make an impression at Grand Slams, it was the first year he played in all four. Federer would then end the year ranked World No. 29. (Wikipedia)
