Marcos' Paris quest got off to a strong start, scoring a 6-2, 6-4 win over wild card Paul-Henri Mathieu, but he would retire from his second round match against Grigor Dimitrov with a right leg injury.
A semifinalist at the BNP Paribas Masters in 2007, Marcos needed one hour and 35 minutes to beat Mathieu on Monday, firing eight aces. On Tuesday, he raced to a quick lead, breaking Dimitrov in the third game, before dropping the first set 6-3 and retiring thereafter.
Marcos concludes his 2016 ATP World Tour campaign with a 25-22 record. It is his most wins in a season since 2012, when he claimed victory 35 times. Currently at No. 37 in the Emirates ATP Rankings, Marcos is also projected to finish the season in the Top 40 for the first time in four years.
