The draw for the BNP Paribas Masters has been made and in the first round, Marcos will face American Sam Querrey.
Beginning in Paris on Monday, the penultimate event of the season will be crucial for those players in last minute contention for a place at the Tennis Masters Cup in Shanghai.
For Marcos, this week is all about getting some matches after his return to the ATP circuit following wrist and back injuries.
All the best players are in contention this week and Marcos will certainly have his work cut out for him as he could face a second round clash with World No. 4 Andy Murray.
Also in Marcos' quarter are defending champion David Nalbandian and No. 9 seed Juan Martin del Potro.
Marcos enjoyed an excellent debut last year in Paris, defeating two Top 10 players en route to a semifinal loss against No. 2 Rafael Nadal.
Stay tuned for all the latest!
