Some good matches tonight in Washington. David Nalbandian, who caught fire a year ago at this time, opens his title defense against James Blake in the marquee match.

American teen Ryan Harrison opens in about 30 minutes against Mischa Zverev. The 19-year-old Harrison just reached back-to-back semifinals in Atlanta and LA.

John Isner is also on tonight against Tobias Kampke and in a match between two former Top 5 players on the mend, Tommy Haas battles Fernando Gonzalez.

Top seed Gael Monfils will play tomorrow against the winner of Tuesday Alex Bogomolov-Ryan Sweeting affair.

After an Atlanta title and LA final, second-seeded Mardy Fish withdrew yesterday from the tournament with a bruised right heel. Fish was replaced in the draw by lucky loser Wayne Odesnik who received a bye.
