Roberto Bautista Agut (ESP) or Dusan Lajovic (SRB)
Round: Third Round
Marcos will turn his attention to the Citi Open in Washington, D.C. as he bids for his first win of the North American hard court season. Marcos was defeated by fifth seed Kyle Edmund 6-3, 7-5 in the first round of the BB&T Atlanta Open on Tuesday, despite firing 11 aces and winning 81 percent of points on his first serve.
Edmund prevailed after one hour and 25 minutes in what was their first head-to-head encounter. It was Marcos' first appearance in Atlanta since reaching the final in 2015.
Marcos will move to the ATP World Tour 500 event in the U.S. capital, where he owns a 9-4 record in four trips. He was runner-up to David Nalbandian in his debut appearance in 2010, while reaching the quarter-finals on two other occasions, in 2011 and 2013.
