The ATP World Tour hard-court tournament in the nation's capital is changing its name to the Citi Open, after being known as the Legg Mason Tennis Classic since 1994.

Classified by the ATP as a 500-level event, it's one of the top 20 tournaments on the men's professional tennis circuit.

In addition to a new title sponsor, the 2012 tournament will include a lower-level WTA event played at the same time and place: July 28-Aug. 5 in Rock Creek Park.

Mardy Fish, at No. 9 the highest-ranked American man, says Tuesday that he will enter the Citi Open after missing the tournament in 2011 because of a heel injury.

Fish says: "I love the city, I love the weather. The court surface is great for me."
