I’ve just been digging around for a link to a column about the economics of professional tennis to add some more context to Boyer’s financial situation. This from Greg Jericho in 2018 is a good explainer, set against the backdrop of Novak Djokovic’s presidency of the ATP Player Council and the push for a new union.

De Minaur exhorts the crowd to enjoy the moment as he breaks Boyer in game three of the third set. Australia’s number one is well on his way to a third round meeting with Argentina’s Francisco Cerúndolo.

Thanks Martin. On centre court Boyer has just taken a comfort break, which is always a smart decision at 0-2 down. Shortly after the resumption of play one of his sneaker’s blows out so he’s forced into another quick wardrobe change. It prompts an interesting discussion on the host broadcaster about how the Stanford grad is part-financed by GoFundMe / Patreon support. It’s a stark reminder of the gulf between the haves and have-nots in professional tennis.

Thanks for following along across the day five morning and into the early exchanges of Alex de Minaur’s second round clash with Tristan Boyer. Jonathan Howcroft will cover the rest of the action from RLA as the Australian closes in on a spot in the third round, but here is a snapshot of what else has been happening in men’s singles around the grounds.

• Gael Monfils has just defeated Daniel Altmaier in straight sets 7-5, 6-3, 7-6(3).

• Ben Shelton (21) has one foot in the third round while leading Pablo Carreno Busta at 6-3, 6-3, 5-4.

• Lorenzo Musetti (16) and Denis Shapovalov are proving all but impossible to split at 7-6(3), 7-6(6).

• Taylor Fritz (4) leads Cristian Garin 6-2, 3-0.

Enjoy the afternoon and what already looks like another cracking evening …

Alex de Minaur wins the second set from Tristan Boyer and is perhaps just one more away from booking his place in the third round. Even when Boyer has been able to test De Minaur, the Australian is pulling out stunning volleys. He looks in fine form and will now hope to close this out in under two hours.

Alex de Minaur and Tristan Boyer both hold as the Australian takes a 5-3 lead in the second set and prepares to serve.

Both De Minaur and Boyer have impressed at the net on RLA with the American particularly keen to surge forward at any opportunity. But those opportunities have dried up in the second set with De Minaur hitting deeper and seemingly harder. The Australian pulls out a perfectly-placed volley that almost spins on a top to stay out of Boyer’s reach, then cleans up another service game to love.

Boyer has had to fight for every service game since his first start but finally cruises through another to love to keep pace with De Minaur in the second set at 3-2. Now the American just needs to test the eighth seed who it must be said is serving with the power and precision you’d expect from such a highly-ranked player.

De Minaur holds to love with his first serve humming. The Australian sends in an ace and keeps Boyer deep enough on the return on a couple more to race through the game in barely three minutes.

Fine tennis from Boyer as he pushes De Minaur deep then bursts forward towards the net to win back-to-back points, the first with a cross-court volley and the next with a powerful smash. The American gets back on the board but is still down a break as De Minaur leads 6-2, 2-1.

De Minaur is running hot on his service games, this time only dropping the one point and finishing with an ace as Boyer. The American hasn’t challenged De Minaur on his serve since breaking him at the start of the clash on RLA.

Alex de Minaur picks up where he left off in the first set against Tristan Boyer although the American doesn’t look like giving up without a fight. Boyer saves a couple of break points but lacks the consistency of his opponent on the backhand to match De Minaur for longer.

A couple of women’s singles results have landed while we have eyes firmly on Alex de Minaur and Tristan Boyer on RLA.

Alex de Minaur keeps rolling along and holds serve to love to win the first set from Tristan Boyer 6-2 in 34 minutes.

Five-in-a-row for De Minaur as he moves to a 5-2 lead and prepares to serve for the first set. Boyer keeps coming to the net and saves a break point with a pinpoint volley but then nets much the same stroke in the next point. De Minaur’s cross-court backhand holds firm as he forces an error from the American to seal the break.

Australian tennis great Lleyton Hewitt is courtside as part of De Minaur’s camp. The former world No 1 sums up what he has made of the clash with Boyer so far.

It would have been nice to get the early break in the first game especially playing with the wind. But Boyer has played pretty well, especially down the far end. He is trying to take it on. We did know he likes to come in but he is taking his chances and he looks very comfortable at the net. He likes going for the drop volley a lot so Alex has to be ready for that.

After an early scare De Minaur has found his rhythm now. The eighth seed breezes through his serve to love even with a 19-shot rally on the third point.

De Minaur holds serve as he works Boyer around the court with clever ground strokes. The eighth seed then breaks Boyer to take a 3-2 lead in the first set.

Tristan Boyer holds after fighting off an early break point for Alex de Minaur. The eighth seed had his chances but some questionable shot selection at the net – including going cross-court when the door was open for a winner down the line at deuce – allows the American to make a reasonably steady start.

Alex De Minaur bounces around Rod Laver Arena as he quickly takes a 0-30 lead over Tristan Boyer. After a couple of errors at the baseline the American tries coming to the net and angles a volley across court that De Minaur is somehow able to chase it down. The return goes long but De Minaur’s speed will now be most apparent to Boyer, if it wasn’t already.

Tristan Boyer will serve first in the second-round match with Australia’s only remaining singles seed in Alex de Minaur.

While we wait for Alex De Minaur and Tristan Boyer to finish their warm-up on Rod Laver Arena, a quick wrap of where we’re at with more second round singles clashes around the grounds.

Alex de Minuar is completing his initial warm up inside the locker room before carrying the hopes of the home nation onto Rod Laver Arena to face American qualifier Tristan Boyer.

The eighth seed was in fine touch as he brushed aside a dangerous first-round opponent in Botic van de Zandschulp in straight sets. Perhaps most importantly, de Minuar is showing no signs of the injury concerns that have plagued him since reaching the last eight at three consecutive grand slams.

The body is exactly where I wanted it to be. I put in countless hours over the better part of six months to get to this point and be feeling good, feeling comfortable, moving, sliding from one side to the other, and not really thinking about my hip.

Emma Navarro (8) has her work cut out against Xiyu Wang after dropping the second set. It’s all even at 6-3, 3-6, 2-2 as the American looks to match her efforts in reaching the third round at Melbourne Park last year.

Emma Raducanu looks relieved as she talks about beating her good friend Amanda Anisimova in straight sets, continuing her journey back from an injury layoff and facing second seed Iga Swiatek in the third round.

This is a slam I love playing at so to make it to the third round means a lot to me. It’s incredibly difficult whenever you play a friend but I had to put that aside today. It was tricky today, it was a little bit windy, but we both had to deal with that. We both, in patches, had moments with out serve, but I was proud to get in back on track.

It’s difficult. The way I play is pretty athletic. I was feeling it but the way I recovered, I was pretty proud of.

It’s a good match for me. Every match I can play against a tough opponent is good for me. We’ve played twice before on clay but this will be the first time on a hardcourt. I have nothing to lose.

Emma Raducanu is showing few signs of the injury concerns that called for a medical timeout at the start of the second set as she holds serve against Amanda Anisimova.

Anisimova to, once again, serve to stay alive.

Ons Jabeur seems to be suffering from illness rather than injury and has had to head to the locker room a couple of times during her second round match against Camila Osorio.

Emma Raducanu calls for a medical timeout and receives some assistance to stretch out the hip, groin and back regions. Hopefully the Brit is just a bit tight rather than suffering anything too serious but she has looked restricted in her movements through this second set. Amanda Anisimova serves while up 3-0.

An upset is well and truly brewing on John Cain Arena as Miomir Kecmanovic takes a two sets lead over 18th seed Hubert Hurkacz at 6-4, 6-4. Last year’s quarter-finalist has sent down nine aces as his serve looks in fine touch but the ground play is off the mark with 22 unforced errors to Kecmanovic’s eight critical at this stage.

Emma Raducanu is subtly grabbing at what appears to be a hip concern. No double faults this time but Amanda Anisimova breaks again and is up 3-0 in the second.

Amanda Anisimova’s power on the backhand is proving the difference so far but the American is also looking to get to the net at any opportunity. She leads 3-1 in the first.

Early danger signs for 18th seed Hubert Hurkacz who is serving to stay in the first set against Miomir Kecmanovic at 3-5 and now down 0-30. The Pole reached the quarter-finals at Melbourne Park last year but is quickly in a spot of bother on John Cain Arena today.

Amanda Anisimova is the first to hold serve as a pair of powerful forehand winners are too much for Emma Raducanu. The American leads 2-1.

Raducanu only needs one as Anisimova sends a backhand too long.

Emma Raducanu and Amanda Anisimova are just completing their warm-up and both should have little to hide ahead of their second-round clash after being regular practice partners and becoming good friends in recent times.

The former US Open winner told Tumaini Carayol what it will mean to play Anisimova for the first time.

I think we’re going to be playing each other many more times in the future. This is the first time. And it’s gonna be a good match. I think she’s a tough opponent. She took some time out, obviously, off the tour, for sort of mental health reasons and just to find herself again.

The Australian contingent has seen better days at their home grand slam, with Jordan Thompson and Ajla Tomljanović among the locals to exit the tournament along with Thanasi Kokkinakis.

If you missed out on the five-set thriller between 15th seed Jack Draper and Australian Thanasi Kokkinakis last night, fret not as we have you covered.

Tumaini Carayol was at Melbourne Park to cover the match of the tournament thus far.

While Jack Snape sat in an at times emotional press conference with Kokkinakis, who was one game away from progressing to the third round but in the end succumbed to injury and an equally determined opponent in Draper.

I know I don’t have forever left, so I don’t know how long I’m going to be out [injured], or what the future holds, even if I can get back to this point if I get [surgery] done. So I’m just [in] a lot of doubt and pretty upset. One thing’s for sure I can’t keep doing what I’m doing, it’s mental torture and physical torture.

Now for the weather. The clouds have returned after rain interrupted day four – at least on the outside courts – on a confusingly wintery summers day. The forecast is only slightly better for today but the eye-test tells us that we should get a lot more tennis in.
