Marcos opened his quest at the Winston-Salem Open with a 6-4, 4-6, 6-4 victory over home hope Donald Young on Tuesday. He needed two hours and 20 minutes to advance to the third round, winning 76 per cent of first serve points and converting four of 10 break points.
Making his fourth appearance at the ATP World Tour 250 event, Marcos got off to a fast start in breaking for 2-1 and eventually claiming the opener on his first set point. He would break again to open the second set, but Young fought back to force a decider. In the third set, Marcos earned the lone break for 4-3 and served out the victory three games later.
Marcos will next face a stiff test against second seed and World No. 17 Roberto Bautista Agut. He was victorious in their lone head-to-head clash, earlier this year in Dubai. They will square off on Wednesday evening, not before 7:00pm local time on Court 2.
