Monfils had the first set almost wrapped up after going up a double break to take a 4-1 lead, but Ferrero re-lived his good old times and came storming back to stage three breaks in a row before serving out the set.
The Frenchman seemed to have recovered at the start of the second set as he took the Spaniard’s serve in the opening game. But the recovery didn’t last very long and Ferrero got right back into it. After breaking Monfils once more to go 4-2 up, he didn’t let the match slip out of his hand and closed it out in 1 hour and 42 minutes.
In round 3, Ferrero will play the winner of the match between the Madrid Open champion Federer and Argentine Carlos Berlocq.
From the remaining first round matches, Poland’s Lukasz Kubot eliminated Italy’s wild card holder Potito Starace 6-3 5-7 6-2 and 11th seed Frenchman Gilles Simon defeated American Donald Young 6-2 7-5.
