Roberto Bautista Agut (ESP) or Dusan Lajovic (SRB)
Round: Third Round
It did not take long for Marcos to secure his place in the final four at the ASB Classic, streaking past Jiri Vesely 6-2, 6-4 in Auckland. He will next face Portugal's Joao Sousa on Friday.
Marcos claimed his third win in three days behind a dominant display, executing his game plan with a strong baseline game and superior agility. After breaking to love in the opening game of the match, he never looked back, breaking again in the fifth game and a third time early in the second set.
Marcos fired 12 aces in total and claimed 24 of 27 (89%) of first serve points during the 70-minute contest. He was also efficient in defending his second serve, winning 67% of such points, and did not face a break point throughout the encounter.
Marcos extended his head-to-head edge over Vesely to 4-0, advancing to his first ATP World Tour semi-final since last July on the grass of Newport. He will next clash against Sousa, in what will be their first meeting. Americans Jack Sock and Steve Johnson battle in the other semi-final.
