That's the biggest roar of the day from Kyle Edmund, as he scurries on to a lengthy Denis Istomin forehand to return with power and precision to win the point.

The British number two follows up with an ace, and Istomin can't deal with a punchy second serve on the next point.

Edmund goes wide with his return on the break point chance. The pair exchange points. Deuce three, only for Istomin to miscue another forehand.

Break point Edmund.

Can Denis Istomin salvage anything from this match? He's looked off the pace, especially since that medical timeout in the first set.

Without wanting to get ahead of ourselves.... Edmund is well on course to reach the third round here for the first time and if he does, next up will be world number 61 Nikoloz Basilashvili of Georgia. First-round defeats for eighth seed Jack Sock, 18th seed Lucas Pouille (and Edmund's win over 11th seed Kevin Anderson) have really opened up this section of the draw.

Meanwhile, spectators at Melbourne Park enjoy a beautiful summer's afternoon while athletic types run around for their entertainment. Perfect.
