Cerundolo retired from his match against Arthur Rinderknech in Paris, handing the Frenchman a hard-fought win. That came after a Brussels week where he was knocked out by Tallon Griekspoor, though one of his forehands still earned a spot among the tournament's best shots.
In Paris, Cerundolo couldn't finish the match, and Rinderknech said he had managed to turn things around before the retirement.
At the European Open in Brussels, Griekspoor ended Cerundolo's run.
Even in that loss, the ATP singled out a powerful Cerundolo forehand as a highlight.
