Boris Becker is to face an ATP investigation over remarks about Thomas Muster after his recent defeat by the Austrian in the final of the Monte Carlo Open. Muster had been carried from the court suffering from dehydration in his semi-final. His comeback from two sets down to beat Becker the next day led to comments by the German which implied that Muster's recovery was drug-assisted. Becker, meanwhile, was beaten in the German Open in his opening match for the second consecutive year, by Jaime Yzaga of Peru in a second-round match.
