Guillermo Ignacio 'Willy' Cañas (born November 25, 1977) is an Argentine professional tennis player. He was born in Argentina's capital, Buenos Aires, and named after Argentine tennis star Guillermo Vilas. His highest singles ranking was 8th (June 2005).
Cañas plays a defensive counter-punching game from the baseline, and utilises his retrieving skills in order to frustrate opponents. He uses a two-handed backhand and his favourite surface is clay, but he is adept on hardcourt and grass too.
After a year of suspension for doping, Cañas returned to the circuit on September 2006 at the challenger of Belém, Brazil.
Cañas holds a record of 5 victories and 2 defeats (3:1 in singles) in Davis Cup matches.
From 1995–1999, Cañas played mainly Challenger Series tournaments, that is, the level of competition directly below that of the ATP Tour. In April 1998, he broke in to the top 100 for the first time, having won three Challenger tournaments in the previous 52 weeks. This allowed him to qualify for more ATP level tournaments, and he reached his first final in 1999, at the ATP Houston. He also began to regularly qualify for Grand Slam tournaments, the most prestigious events in tennis.
In 2001, after a right wrist injury the previous year, he climbed from 227th place in the ATP rankings to the 15th, and was named ATP Comeback Player of Year. Cañas had won the first ATP level title of his career that season, in Casablanca, and reached the final of three other tournaments. In addition to this, he reached the fourth round of a Grand Slam tournament for the first time, achieving this result on two occasions, at the French Open and Wimbledon.
In the 2002 ATP Masters Series of Canada, an unseeded Cañas won his first ATP Masters Series title in Toronto, defeating Andy Roddick 6–4, 7–5 in the final. Cañas's path to the final saw him defeat a renowned set of players, including world number two Marat Safin, and top ten ranked Yevgeny Kafelnikov and Roger Federer. Cañas was also the first Argentine to win the Canada Open since Guillermo Vilas in 1976, and also the first to win a Masters Series shield (the Series was created in 1990).. Cañas won one other tournament in 2002, the Chennai Open, and reached in the finals in Casablanca and Stuttgart. He also emerged as a more potent force at the Grand Slams, as he reached his first quarter-final at the French.
Cañas vowed to fight the ban, claiming he was innocent of the charges against him. Cañas took his case to the Court of Arbitration for Sport. His perseverance paid off on May 23, 2006, when he was acquitted of deliberate performance enhancement through illegal substances, since the substances were in a prescription medicine. He was, however, considered careless in not checking the medicine before ingesting it. He was allowed to return to full professional activity from September 11, 2006, and the money prizes acquired before the suspension were restored. Cañas's points, which determine a player's ranking, were nil upon his return, as they had expired.
On March 11, 2007 Cañas defeated ATP ranked number one Roger Federer 7–5, 6–2 at theIndian Wells Masters, ending Federer's streak of 41 consecutive victories, 5 short of Guillermo Vilas's record on ATP Tour matches. He defeated Federer again (7–6, 2–6, 7–6) 16 days later at the Miami Masters to back-up his victory at Indian Wells. This double victory made him the only player (besides Rafael Nadal) to have defeated Federer in consecutive tournaments since 2003. Cañas told the New York Times that, "I came back very motivated, I came back with a lot of energy."
At the 2007 Miami Masters, Cañas once again defeated Roger Federer, and became the first qualifier to reach the semifinals of this tournament. In the semifinal, he beat Ivan Ljubičić, the seventh seed, 7–5, 6–2 to make it to the final. However, the Argentine lost to rising talent Novak Djokovic of Serbia in straight sets. To get to the final, Cañas defeated Tim Henman, Juan Carlos Ferrero, Richard Gasquet, Roger Federer, Tommy Robredo, and Ivan Ljubičić, in respective order, before losing to Đoković. In spite of that loss, Cañas jumped 121 positions to reach the 22nd place in the ATP ranking as of April 30, 2007, the highest jump so far in the year.
Cañas reached the final of one more tournament in 2007, the Torneo Godó in Barcelona, where he lost to clay-court ace Rafael Nadal. Cañas commented afterwards that he believed he would be a strong contender at the French Open. However, his bid was thwarted for a third time at the quarter-final stage, as Nikolay Davydenko denied him and opportunity to play Federer for a third time in the next round. Having set himself a goal of finishing in the top 20, Cañas finished the year in 15th, equalling his best finishes from 2002 and 2003.
