• Federer beats Marton Fucsovics 4-6, 6-1, 6-2, 6-2• ‘He’s a heck of a player,’ says world No 100 SandgrenTennys Sandgren is not easily overawed, which is just as well, given he owns a name that invites disbelief and is going to play
Roger Federer in the quarter-finals of the
Australian Open on Tuesday.

The world No 100, who still lives in the small Tennessee town of Gallatin – about 30 miles from Nashville – in which he was born 28 years ago and mainly makes noise in slams because of his archly obvious moniker and occasional flashes of muscular brilliance, on Sunday earned the right to play Federer in the first slam of 2020.
