What is slowing down Ivo Karlovic?

The 37-year-old's results and number of aces (75 in the first round) would strongly suggest that nothing is slowing Dr. Ivo down. Not even his age.

Behind the scenes an Aussie has come to Johanna Konta's rescue supplying her with spare black gut to string her racquets for tomorrow's quarterfinal against Serena Williams. If he goes much further with Sam Stosur in the mixed doubles he might need it himself.

Stan Wawrinka on his coming Australian Open semifinal matchup against Roger Federer: "for sure now I'm more confident with myself. When I step on the court, doesn't matter who I play, I know what I have to do if I want to win. Against Roger, it's always special because he's so good. He's the best player of all time. He has answer for everything. But I managed to beat him in a Grand Slam, so we'll see." #ausopen

The comeback continues for Roger Federer, who moved into his 13th Australian Open semi in the last 14 years with a masterful 6-1, 7-5, 6-2 win over unseeded Mischa Zverev. Federer's resounding comeback from a six-month layoff to mend from a knee injury has been terrific. He's 35 but moving around and making shots like he did in his heyday. He faces good friend and Swiss countryman Stan Wawrinka next. It will be his toughest match so far.

Roger Federer has seen Mischa Zverev gain confidence as their quarterfinal at the Australian Open has gone along, but Federer still eked out the second set too, 7-5. Zverev, as expected, has served and volleyed throughout -- a rarity in the game today but a tactic possible on these fast courts. Federer has had to try more passing shots in this match that he normally might attempt in five other matches. At times he's also beat Zverev to the net first.

A ray of hope: Mischa Zverev, with help from a net-cord winner, breaks Roger Federer to inch ahead 2-1 in the second set of their Australian Open QF. Federer blitzed to a first-set win in just 19 minutes.

As if Roger Federer doesn't have enough going for him, he wins challenges on errant line calls too. Maybe you really can have it all. #ausopen

Fans with shirts that read 'R F' and Swiss flags painted on their faces make their way to Roger Federer's quarterfinal against unseeded Mischa Zverev, who upset top-ranked Andy Murray a round earlier. Some folks walking around the corridors at Rod Laver Arena claimed tickets for tonight's match were selling for $600-$700, or as much as two to three times face value. #ausopen
