Rafael Nadal crashed out of his comeback event after a two-month layoff, falling to South Africa's 50th-ranked Lloyd Harris on Thursday in a third-round match at the ATP Citi Open.

The 35-year-old Spanish left-hander, a 20-time Grand Slam champion, lost to 14th seed Harris 6-4, 1-6, 6-4 in only his second match on the Washington hardcourts.
