LOS ANGELES (AP) - Mardy Fish moved a step closer to his second straight title, beating No. 8 seed Igor Kunitsyn of Russia 6-2, 6-4 on Friday to reach the semifinals at the Farmers Classic.
The top seed's next opponent will be 19-year-old Ryan Harrison, who outlasted Yen-Hsun Lu of Taiwan 3-6, 6-3, 6-4 in 2 hours, 24 minutes.
Harrison became the first American teenager to reach back-to-back semifinals since Andy Roddick in 2002. Fish beat Harrison in the semifinals at Atlanta last week on the way to his first title of the season.
Fourth-seeded Thomaz Bellucci defeated Alex Bogomolov Jr. 1-6, 6-4, 6-1 and will play the winner of Friday's late match between second-seeded Juan Martin del Potro of Argentina and Ernests Gulbis of Latvia.
