The World Group was the highest level of Davis Cup competition in 2005. The first-round losers went into the Davis Cup World Group Play-offs, and the winners progress to the quarterfinals. The quarterfinalists were guaranteed a World Group spot for 2006. On February 13, 2006 the International Tennis Federation (ITF) announced that Karol Beck had tested positive for the beta agonist clenbuterol during the semifinal for Slovakia against Argentina. As a consequence, the ITF suspended him from the game for two years.
