Marcos became the first to reach the third round at Winston-Salem Open, defeating Jiri Vesely 6-2, 7-6(3) on Monday. It was his second straight-set win in as many days, after blasting Ricardas Berankis 7-5, 7-5 to open his Winston-Salem campaign on Sunday.
Marcos needed one hour and 25 minutes to defeat the 16th seed Vesely, firing four aces and claiming 88 percent of first serve points. He converted all three break points earned while saving three of four faced.
Marcos opened proceedings on Monday afternoon with a bang, breaking in the third game of the match and again in the fifth game. He would take the opening set after just 35 minutes. Both players exchanged breaks in the second set and Marcos would eventually take it in a tie-break, claiming his first match point.
Marcos will bid to reach the quarterfinals in Winston-Salem for the second time (also in 2011) when he faces either top seed Roberto Bautista Agut or Dusan Lajovic next. Marcos and Spain's Bautista Agut have split their two previous encounters. He has previously never faced Lajovic.
