Qualifier Somdev Devvarman of India recorded the biggest win of his career as he upset 6th seed Marin Cilic of Croatia 7-5, 6-4 to advance to the third round of the Legg Mason Tennis Classic.

Defending champion and No. 2 seeded Juan Martin del Potro of Argentina avoided another upset, as did 10th-seeded Tommy Haas of Germany.
 
Del Potro pulled through a 4-6, 6-3, 6-2 win over Taiwan’s Yen-Hsun Lu in the second round, and Haas also won his second-round match, 6-1, 4-6, 6-4 over Canada’s Frank Dancevic.

Asked if his first career win over a top-20 player was his most significant victory, Devvarman said, “Definitely, definitely.”

“When I’m playing well, I like hitting the ball deep,” Devvarman said. “I felt like today I did that very well.”
