The 21-year-old Russian seeks his first ATP title. Fish, ranked 21st, is trying to become the first top seed to win the title in the event's 17-year history and the first American to win it since 2003, when Jan-Michael Gambill beat Fish in the final. Fish, bidding for his 13th ATP final, has not won a title since claiming his second career crown at Houston in Aprtil of 2006 on clay.
