Roger Federer confirms his participation on Estoril tournament in 2010 to defend his title

ATP World Tour No. 1 and former champion Roger Federer has confirmed he will return to compete at the Estoril Open, an ATP World Tour 250 clay-court tournament, from 1-9 May 2010.

The Swiss superstar snapped a five-month title drought by winning his 54th career ATP World Tour trophy at the Estoril Open (d. Davydenko) in May 2008, when a record 53,888 spectators visited the Estadio Nacional.

Federer is the all-time Grand Slam title-leader, having broken Pete Sampras’ record of 14 triumphs (1990-2002) at The Championships, Wimbledon, in July 2009.
