Marcos will conclude his 2017 campaign with two tournaments on the ATP Challenger Tour.
Looking to vault himself back up the Emirates ATP Rankings (currently at No. 93), Marcos will contest next week's Slovak Open in Bratislava, Slovakia, and the Trofeo Citta di Brescia, in Brescia, Italy.
Marcos previously competed in Bratislava in both 2004 and 2005, winning the title and then reaching the semifinals. It will be his first trip to Brescia.
Marcos is just one month removed from reaching the final at the ATP World Tour event in Chengdu. He is looking to carry the momentum from his strong week in China to the indoor hard-court events in Europe.
