Roger Federer becomes first man to win 300 Grand Slam matches!

Long in the shadow of the Swiss master, Dimitrov played some irresistible tennis to prise a set but was powerless to maintain the intensity under a closed roof at Rod Laver Arena.

Federer, however, simply lifted a gear, taming an occasionally wayward forehand before speeding away from the Bulgarian player nicknamed 'Baby Fed'.

Capturing an early break in the final set, four-time champion Federer sealed the match with an imperious forehand to set up a clash with another young gun in Belgian David Goffin.
