Marcos moved into the second round at the Wimbledon Championships on Tuesday, as Dominic Thiem retired early in the third set of their opening encounter.
Marcos led 6-4, 7-5, 2-0 when his seventh-ranked opponent was forced to stop due to a back injury. The match, which lasted one hour and 37 minutes, featured 10 aces by Marcos, as well as three breaks of serve.
It will go down as his first Top 10 win in two years, since defeating Tomas Berdych on the grass of Halle in 2016. He now has 21 wins over Top 10 opponents in his career, with three coming at Wimbledon.
Next up for Marcos is Russian rising star Karen Khachanov on Thursday. It will be their first head-to-head encounter.
