Roberto Bautista Agut (ESP) or Dusan Lajovic (SRB)
Round: Third Round
Marcos survived a three-hour rain delay to move into the second round at the Citi Open on Tuesday, streaking past Edan Leshem.
Marcos spoiled the ATP World Tour debut of the 20-year-old Israeli, prevailing 7-6(1), 6-0 in one hour and 43 minutes. He fired six aces and claimed 82 percent of points on his first serve. He did not face a break point, while converting on three of five of his own.
Neither player faced a break point in the first set, as Marcos pulled ahead 5-1 in the tie-break before the stormy weather arrived. Play was suspended for three hours and Marcos was a dominant force when the match resumed, taking the opening set and not dropping a game in the second.
It was Marcos' 10th match win in Washington, where he's making his fifth appearance. A finalist there in 2010, the ATP World Tour 500 event is one of his favourite events. He will next face American Ryan Harrison in Wednesday's second round. Harrison is coming off a runner-up finish in Atlanta, but Marcos leads their head-to-head 2-1. He most recently prevailed in four sets at last year's US Open. The match is scheduled for third on Grandstand 1, not before 5:00pm local time.
