Australian Open third-round picks: Johnson to lead American charge in Melbourne
The Californian is playing well enough to surprise the veteran Ferrer, while Isner will progress if he maintains his incredible record in tie-breaks
Steve Johnson has enjoyed a smooth progression to this stage of the tournament, winning six of his six sets so far.
And the American is excellent value to beat David Ferrer, who was impressive against an ailing Lleyton Hewitt last time out.
But the Spaniard has lost to Bernard Tomic, Jeremy Chardy, Marcos Baghdatis and Jack Sock in recent months and Johnson is capable of adding his name to this list.
When John Isner and Feliciano Lopez face each other on a tennis court, a tie-break is never far away.
The big-serving duo have clashed on six occasions and 10 of the 19 sets have been settled by a seven-point shoot-out.
Isner is statistically the second best tie-break player of all time - winning more than 60 per cent - beat Lopez 7-6 6-7 7-6 in their last meeting at Queen's. Expect a similar outcome in Melbourne.
Stan Wawrinka has started this year in blistering form. The powerful Swiss was a winner two weeks ago in Chennai and is yet to drop a set so far this season.
The 2014 Australian Open winner champion has been consistent at the grand slams, too, reaching at least the quarter-finals at his last six.
Lukas Rosol, meanwhile, has won only 41 per cent of his matches and the majors. There is only going to be one winner here.
Two form players meet collide on Saturday as Brisbane champion Milos Raonic takes on Sydney winner Viktor Troicki.
Raonic endured a disappointing 2015, but looks revitalised this season and has already blasted his way to wins over Federer and Tomic.
The Canadian has won two of his three past meetings with Troicki and should be able to use his monster serve to record another victory.
World No. 74 Andrey Kuznetsov will be amazed to be facing a lower-ranked opponent and the talented Russian should take advantage of his kind draw by progressing.
Dudi Sela is a 30-year-old who plays almost exclusively on the Challenger circuit and is presumably as shocked as everyone else to be in the third round.
Kuznetsov pushed Rafael Nadal to three sets in Doha two weeks ago and has already beaten 30th seed Jeremy Chardy this week. He will win again.
A £10 on the five-fold accumulator returns £138.93*.
