Dish-Houston

Tennis fever has clearly hit Houston!! Mardy Fish became the No. 1 player from the U.S. on Wednesday with a straight sets win over David Ferrer in the Miami quarterfinals. When the new rankings are released Monday, Fish will be ranked higher than Andy Roddick, who has been the top American since 2008. Fish is projected to climb from his current career high of No. 15 to No. 11 by reaching the Miami semifinals, and would likely reach the Top 10 if he were to advance to the Miami final.

Ryan Sweeting's wild card brings the total number of Americans in the field for 2011 to eight, including six of the seven Americans who are ranked in the Top 100. The 23-year-old played a brief collegiate career at the University of Florida and was the 2005 US Open junior champion. This will be Sweeting's third main draw appearance in Houston, including last year when he reached the second round as a qualifier before falling to Chile's Nicolas Massu in a third set.

Four players have been added to the field this week. In addition to Sweeting, former Australian Open finalist Rainer Schuettler of Germany, Russian Igor Kunitsyn and Germany's Mischa Zverev have joined the field. Schuettler took the place of 2010 champion Juan Ignacio Chela, who withdrew for personal reasons, while Kunitsyn and Daniel entered the field after all possible special exempt spots from Miami were eliminated.

Twenty-four of the field of 28 players has been set, with four more to enter through this weekend's qualifying tournament, including Americans James Blake and Ryan Harrison, who join Sweeting as the wild card entrants. The top four seeds for this year's event will be Fish at No. 1, 2010 finalist Sam Querrey at No. 2, Spain's Guillermo Garcia-Lopez at No. 3 and American John Isner at No. 4. These four players will have first round byes.
