Roger Federer's first match at the Rome Masters will come against a player who's given him all sorts of trouble — Guillermo Canas. Canas rallied past Italian wild card Gianluca Naso 6-7 (8), 6-3, 6-2 Monday to set up a clay-court meeting with Federer, who had a first-round bye. The tournament began with an upset when ninth-seeded Richard Gasquet lost to Peruvian qualifier Luis Horna 6-4, 6-1 in the first match on center court.
