A remarkable result on Margaret Court Arena.

Men’s ninth seed Andrey Rublev is OUT!

And he has fallen to Brazil’s 18-year-old qualifier Joao Fonseca, making his Grand Slam debut. Remember the name.

It’s a day he will not forget in a hurry, that’s for sure, as he wraps up a stunning straight-set victory over the 10-time major quarter-finalist.

A frustrated Rublev took out his frustration on his racquet as Fonseca fought back from a break down at 3-1 in the third set to force a tie-break.

And the talented Brazilian condemns Rublev to his first Australian Open first round exit in six years with his first match point to huge cheers in Melbourne.
