Feliciano Lopez ended Lleyton Hewitt's last appearance in the Citi Open with a 4-6, 7-5, 6-3 second-round victory Wednesday over the two-time major champion.
The seventh-seeded Lopez wound up with a 44-23 edge in winners, including 15 aces, in the 2-hour, 10-minute match.
Lopez lost his first four career matches against Hewitt but now has won the past two. Hewitt is a former No. 1 player who has said he will retire after January's Australian Open and received a wild-card entry into Washington's hard-court tuneup for the U.S. Open.
Next for Lopez is a match against Sam Groth, who beat Viktor Troicki 6-3, 6-4.
