The Washington Kastles aren't the only tennis to see in D.C. this summer: The Citi Open has been a midsummer tradition in Rock Creek Park since 1969. You won't catch the Djokovic, Nadal or Murray types here, but there are plenty of solid players to watch in this week's field, including world No. 7 Jual Martin del Potro, No. 11 Tommy Haas and No. 13 Milos Raonic. Heavy hitter Gael Monfils and American hero John Isner -- he the winner of the longest match in professional tennis history -- are also included in the field. After qualifying matches on Saturday and Sunday, the main draw begins play Monday at 2 p.m.
