On the eve of Roland Garros, Marcos has begun a new partnership with coach, Eduardo Infantino.
Marcos, who has been training with former professionals Franco Squillari and Younes El Aynaoui in the past couple of weeks, will play his first tournament with Infantino at the French Open.
Infantino has previously worked with former World No. 3 David Nalbandian, who reached the Wimbledon final in 2002, and current World No. 5 Juan Martin del Potro – who had a breakthrough season in 2008 by winning four ATP World Tour titles.
Marcos’ first match under Infantino’s tutelage will be against Juan Monaco in the first round of the French Open.
