Challenger to Champion: Casper Ruud, Arthur Fils, Frances Tiafoe and more take the first step

From teen phenoms to veteran grinders, every professional tennis player takes a different road in their journey to the top of the game.

But somewhere along the way, there’s always a stop on the ATP Challenger Tour—an essential stepping stone for young players, a proving ground for rising talent and a comeback trail for established veterans, all in one.
