DELRAY BEACH, Fla. (AP) Second-seeded Mardy Fish defeated Ricardo Mello 6-2, 6-1 in a matchup of former titlists in the second round of the Delray Beach International Tennis Championships on Thursday.
The American gained the quarterfinals and will play the winner of Thursday night's match between Juan Martin del Potro of Argentina, the 2009 U.S. Open champion, and Teymuraz Gabashvili of Russia.
Fish won the Delray title in 2009 and has reached the quarters at least four times. Mello won his lone career title here in 2004.
Fish broke Mello's serve in the first and fifth games of the first set and only allowed the Brazilian to hold serve in the opening game of the second.
Qualifier Alejandro Falla of Colombia upset eighth-seeded Adrian Mannarino of France 6-3, 6-2 in another second-round match.
