Wee hours for Konta and Muguruza

It was the latest-ever start time for an Australian Open match: precisely 12:30 a.m.  And it wasn't over until after 3 a.m., when Garbiñe Muguruza finished off Johanna Konta 6-4, 6-7 (3) 7-5 to move into the third round. The tournament flinched here, big time. The previous match involving Alexander Zverev was a marathon. And a brief notion to play on Court 3 was aborted because of ... excessive seagull poo (yup). “I don’t agree with athletes having to physically exert themselves in the wee hours of the morning,” Konta told BBC Radio Five Live. “I don’t think it’s healthy. I think it’s quite dangerous.”

Not Rafa’s brand, but fair balls

The switch from to Dunlop balls in Australia this year is getting mixed reviews. It's like asking players about court speed.  Rafael Nadal thinks they're "fair for everyone." "With colder conditions, the ball is bigger ... a little bit more slow, no? Not that high bounces that sometimes we used to have here," he said. "It's a good quality ball. I can't complain about the ball. Personally if you ask me, I like little bit faster ball than this one. But I can't say is a bad ball because is a good ball."

Melbourne weather “stick”y for Tsonga

Wondering why Jo-Wilfried Tsonga's stick stash went off to the stringer, early in his loss to Novak Djokovic? "It's two different tournaments,"  Tsonga said of the speed difference between Court 7 and Rod Laver Arena. Next: the weather. "I had two tensions in my bag. When I left the hotel, it was 31C. I said, 'It’ll be hot, I’ll string tight.' The previous day they were too loose; I hit the first 10 forehands almost in the stands." Not so on Laver. At 28 kilos, the ball wasn't even making it to the net. Out they went, returning at 26 kilos.

Wardrobe fail out on the field courts

Here's the problem with the ultra-light shorts the fellas are wearing these days. On a hot, sticky, sweat-producing, dripping day in the heart of an Australian summer, they can too easily lead to a major wardrobe malfunction. First rule of thumb: if you're wearing white shorts, make sure you've got white undershorts. Or else it's not pretty. This fella's opponent, with the same clothing sponsor, chose black shorts despite the heat (and won). Believe it or not, at Wimbledon, that code violation would have had the wardrobe police make him change (although they supply alternatives).

McEnroes, Li Na lead legends event

The McEnroe brothers will team up for the legends tournament, which takes place during the second week of the Australian Open. Elder brother John tends to play these more often. But it's always neat to see the siblings compete together. The  legends mostly are on site working as commentators. It's a handy way to pick up some extra change. New to the roster this year is Li Na, playing her first legends event in Melbourne since winning the women's singles title in 2014 – and giving this epic speech that people still remember fondly.

Nick Kyrgios, tennis analyst

A plaid-clad Nick Kyrgios tried his hand at commentary Friday during the match between Roger Federer and Taylor Fritz Friday. It was a good performance. The veteran Jim Courier expertly guided him and elicited good insight. Kyrgios couldn't contain his Federer admiration.

"He almost baits you to come forward – especially guys like Fritz who aren’t so comfortable. I can’t think of anything worse, to be honest," Kyrgios said. "When Federer is in front, he’s the most impossible player to stop. I try to do anything he hasn’t seen before. But he’s seen it all. So it’s tough."

Murray out of Marseille

Whether the Open 13 was speculating, or actually knows something, it has announced that Andy Murray is pulling out his planned participation in the ATP tournament the week of Feb. 18. "Still suffering with a hip injury, Andy Murray is expected to undergo another surgery and therefore has withdrawn from his upcoming tournaments – notably the Open 13 Provence." (The English version puts it a bit differently: "May have to undergo another surgery"). Tomas Berdych, still alive in Melbourne, takes his spot in the main draw. As to what Murray will do, the answer should come fairly soon.

Tournament director Jérémy Chardy

In keeping with the ongoing theme of tennis conflicts of interest, French player Jérémy Chardy is the tournament director at a new Challenger in Pau, France next month. Called the Teréga Open Pau-Pyrénées, it's an $80,000 US event . As a top 50 player, Chardy can't technically enter his own tournament. He needs a wild card. But hey, he's got a pretty good connection there.  The 31-year-old won't have time to be too hands on. He's entered Montpellier, Rotterdam and Marseille the three weeks leading up to the event. (Looks like he posed for the ad, though).

Tag Heuer – Next Gen timepiece

In the tennis watch sponsorship sweepstakes, the Tag Heuer brand is building from the Next Gen up. The Swiss watchmaker is a sponsor at the Next Gen Finals in Milan. And it already had rising stars Denis Shapovalov of Canada and Frances Tiafoe of the U.S. before adding 18-year-old Félix Auger-Aliassime at this Australian Open. The company unveiled its stable of ambassadors (and their timepieces) at an event at the start of the tournament with Auger-Aliassime (18), Hyeon Chung (22), Olga Danilovic (17), Tiafoe (20) and Shapovalov (19).  Romania's Ana Bogdan, 26, is sort of the outlier in the pic.

Lenny Federer in the house

Dad Roger wasn't expecting one of his younger sets of twins, 4 1/2-year-old lookalike son Lenny, to take in a full set of his third-round match against Taylor Fritz Friday. But the kid got his fair share of attention – no surprise. He also got a bit of a piece of Federer coach Ivan Ljubicic.  "I didn't even know he was going to come to the stadium. When I peeked over and he was sitting here I was like, 'Oh, wow, okay, so we have a special guest – for me, anyhow,' " Federer said on court.
