Marcos returns to the Citi Open this week with fond memories from past visits. Washington, D.C. was the site of his first ATP World Tour 500 final in 2010 and he has compiled a 9-4 record at the hard-court event.
On Tuesday, Marcos will look to keep the good fortunes rolling in the U.S. capital city, facing Israeli qualifier Edan Leshem in his opener. The 20 year old is making his ATP debut. It does not get any easier from then on, however, with Sunday's Atlanta runner-up Ryan Harrison waiting in the second round. Third seed and 2014 champion Milos Raonic also looms large in the third round, with Americans John Isner and Jack Sock in Marcos' quarter of the draw as well.
Marcos is bidding for his first win of the North American hard-court season, following a first-round defeat to Kyle Edmund at the BB&T Atlanta Open.
