"There may be only one tennis player in the world who wishes he had taken it a bit easier on Roger Federer. Reto Schmidli, 31, a police officer and part-time psychology student in Arlesheim, Switzerland, is the only person who has “double-bageled” Federer, that is, beaten him, 6-0, 6-0."
"He was a really bad loser,” said Madeleine Bärlocher, Federer’s first coach at the Old Boys Tennis Club in Basel. “After he’d lose a match, he’d sit under the umpire’s chair and cry for half an hour sometimes. The other players would already be in the clubhouse eating sandwiches, and he’d still be crying on the court.”
Reto Schmidli, GOAT.
