Retirement in Mid-Match: Why Does it Happen?

[prairiegirl]

In today's high stakes tennis we're seeing an increasing number of players quite mid match. I don't recall this happening when I first started watching tennis during the Borg-McEnroe era. Maybe it happened and I didn't pay attention. However, I fully believe the tennis calendar is out of control. Yes, players can pick and choose where they play and when. But imagine having to constantly sleep in hotels, play in different time zones, eat restaurant food, and your body just can't always keep up. So, I asked AI to analyze top players and this is what I got:

Novak Djokovic has etired mid‑match a total of 14 times in his entire professional career across all ATP events, including Grand Slams. This figure comes from combining the well‑documented 7 Grand Slam retirements with ATP‑level retirements recorded in match archives and reporting.

Rafael Nadal retired mid‑match five times in his entire professional career.

Andy Murray retired at 31 after two major hip surgeries – extremely unusual for a young, fit athlete.

Why does Musetti tend to have mid match issues?

His fitness is good, but not optimized for five‑set tennis

He’s fit in the sense of:

• speed
• flexibility
• shot tolerance

But he’s not yet built for:

• long, grinding five‑setters
• heat management
• sustained explosive movement over hours

This is a different kind of fitness — the Djokovic/Nadal kind — and he’s not there yet.

Sinner has retired mid‑match multiple times, with at least three clearly documented retirements in major ATP events (Shanghai 2025, Cincinnati 2025 twice reported, and another Shanghai report). These were due to:

heat stress

illness (fever/flu)

cramping or injury

When we lost in Mario we had to start from the beginning lol.

 

[Shaolin]

The game is more physical and powerful now than when you started watching in the 80s. The way they hit them is like a warmup now.

I'm glad they changed that because starting over sucked. Save states were a good change for everyone.

 

[Robert F]

The physicality of the game has just gone up over the years.
The way Carlos sprints on ever point.
The way Carlos and Sinner hit out of the extreme corners of the court.
The way everyone in the top hundred can defend just puts more cumulative stress on the body.

So they are stressing the body more.
Couple that with the level of fitness they have allows them to put more stress on their body than athletes of the past.

 

[ibbi]

I don't think the heat is an issue. He played a very long match with Mahac under the sun the same day that Sinner was melting, and he had zero issues.

I don't even know that the long and grinding five setters can be blamed given he only had one, and he backed it up brilliantly against Fritz. Last year at Roland Garros he didn't have any, and it still caught up to him. He's definitely had that issue in the past, but it seems to me like that, at least, is behind him.

Explosivity, especially given the seeming location of the injury, definitely seems more like the factor.

This is the real answer

Retirements happened even more back then, injury timeouts were basically not allowed at many events - or if allowed in a very limited capacity. And never any treatment for cramps even on changeovers. Sinner would have been defaulted for time violations for his cramping episode. Players cramped all the time back then(and no roofs)

It's funny some posters here still think Becker should have been defaulted after rolling his ankle at '85 Wimbledon(he literally took 30 seconds to test out his ankle before playing while umpire refused any trainer. Today a player stays on the ground for a much longer time and the umpire actually runs over to check on them! Zero chance any umpire does that back then)

And bathroom breaks...lol at that happening with any regularity back then, even as "tactical" after losing a set (even that was beneath Connors, Mac etc)

You're only thinking this is an issue now because every single match at every single event is available for viewing. USO didn't even have first week coverage until mid 80s I think(and of course they didn't stay on air that long). And no internet to find out everything that was going on, even to find out the final score of a match you were watching when they left the air. Just check out the draw sheets, plenty of ret's.

And the calendar was even worse then, way more events on tour(again 90% of them were not televised)

 

[junkieballer]

Rafael Nadal retired mid‑match five times in his entire professional career.

Nadal 9 times

 

[Bartelby]

Musetti seems to have an ongoing problem with that part of his body.

It's erroneous thinking to assume lack of fitness due to this retirement.

 

[GabeT]

The game is more physical and powerful now than when you started watching in the 80s. The way they hit them is like a warmup now.

Every so often I watch some old match from the Borg/Jmac era. While they can be fun it’s like watching a couple of Sunday players at the local tennis court relative to today’s tennis. They barely move (again, relataive to today’s tennis).

And if you read bios from players from the last the training was a fraction of what it’s today.

 

[Mainad]

Musetti needs to get a handle on his fitness otherwise his career is going to be cut sadly short.

 

[Super Tennis Man Yes]

Players are faster, courts are slower than ever, balls are terrible, schedule is longer, and it's harder than ever to win a point. Mussetti played a lot of tennis last year, and it's looking like he's gonna play a lot of tennis again this year. It's unsurprising injuries would start mounting up.

 

[Bartelby]

As the game gets tougher fewer rise to the top, perhaps, as genetic predispositions to bodily injury increases.

Career marred by injury is the new norm.

[sportsfan1]

This is the second time twosetti has had injury issues against Nole.

 

[LOBALOT]

Maybe he and the other Italians need to go back to doping. The only one who seems to be playing well is the one who was rewarded by being given the winter vacation I mean ban during winter vacation so called punishment.

In a related note anyone notice that Swiatek seems to be struggling since she fell under scrutiny when she was found to be doping.....

 

[ChocoLab]

Yes but the players are supposedly so much bigger and stronger and more athletic now, so they should be able to handle it.

The Djoker had a handful of retirements in his 20-year GOAT career. The Iron Man Fed only had one!
Meanwhile, the young Sinner --the heat-sensitive redhead-- has had several episodes in recent months. Today's players are softer.

Today's players also like fire in the belly. Just happy to be there. It is embarrassing.
Just look at Shelton. Has lost 23 straight sets to Sinner!

I agree. About 10 years ago I happened upon an old Nastase match on TV, When I landed on the channel I thought, ''oh good they are still in the warmup'' but then realized they were actually playing Just a big difference in the game now.

They made fun of the 'glass Samurai', Musetti's is even worse.

everyone in top 100? well, that's a big stretch. maybe top 50. Opelka and many others are terrible defenders. Peak Chang would eat them up in a race.
- cumulative stress is probably from the sliding and joints. It's a 50/50 toss-up from ortho surgeons surveyed about its effect on the knee and joint stress.

Tennis off-court training has changed dramatically. A lot more core, strength plyometrics, yoga/pilates, cardio.
Freakin' Fed used to do half-height hurdle jumps for footwork drills pre-2010.
Obviously, nobody's anatomy/bone density, soft tissue are the same as another, thus it's a bigger benefit for most while for others no gain or even a negative.
Players in the 90s Sampras/Agassi/Becker/Edberg did train and were very athletic.

Didn't she win Wimbledon?

Djoker used to wilt in the sun exactly like Sinner ... and he is not a redhead.

[Waves]

The game has become a sport of attrition at this level. It’s brutal. We would see many more withdrawals if the women played 3/5 also. It would be a bloodbath. I think Novak will be the last of these kinds of players that last, unless there is some modification of the equipment and courts.

The only reason they retire more is global warming

 

[ruripi]

80-90s tennis are made of S&V.
Most points decided within 5 shots without tough sprint. Watch Becker - Sampras 1996 tour final. Not that much long rallies.
After late 2000s, S&V style is dead and players need to sprint much more than 80-90s players. Only few players like Federer can adopt old S&V style to reduce pressure on their body with keep winning. See what happened to Djokovic when he tried to bring more net play yesterday.

The Iron Man relied on Jarvis too. The thing is that all of the knowledge comes from somewhere and it unfortunately is not the God. There's a lot more to considered than the programmed intelligence can offer you officially.

Didn't she win Wimbledon?

Who did she play ?

 

[LOBALOT]

The only reason they retire more is global warming

They need to switch all majors to fast-4 format and best of 2 sets.

Any match scheduled where the temperature is not between 70 and 75 degrees must be immediately rescheduled or moved indoors.

We also need to go back to ball kids handing the players a towel between each point and players need to have the option for a wardrobe change and coaching visit on each change over.

Any twinge of pain or being winded is an automatic 15 minute rest period where the players can head indoors to see their physio.

The game is just too brutal and tough.

TRUE! Still though players, before 1980, had it tough too. Play was continuous, no times out for ANY reason, no toweling off after every point or so, they drank water instead of nutritional drinks, players did not have personal full time coaches, physios etc..

AI chatbots are clueless. Nadal has nine retirements:

1. 2005 Auckland R32 vs Hrbaty, 3-6 RET
2. 2006 Queen's QF vs Hewitt, 6-3 3-6 RET
3. 2007 Sydney R32 vs Guccione, 5-6 RET
4. 2007 Cincy R32 vs Monaco, 6-7(5) 1-4 RET
5. 2008 Paris QF vs Davydenko, 1-6 RET
6. 2010 AO QF vs Murray, 3-6 6-7(2) 0-3 RET
7. 2016 Miami R64 vs Dzumhur, 6-2 4-6 0-3 RET
8. 2018 AO QF vs Cilic, 6-3 3-6 7-6(5) 2-6 0-2 RET
9. 2018 USO SF vs del Potro, 6-7(3) 2-6 RET

Nadal has an additional 7 matches where he withdrew due to injury

Other info it missed: Murray has three retirements, Sinner has seven, and Musetti nine.

 

[jm1980]

The Djoker had a handful of retirements in his 20-year GOAT career. The Iron Man Fed only had one!

Fed never retired from a match that he was already playing in, but he does have five withdrawals:

1. 2008 Paris QF vs Blake
2. 2012 Doha SF vs Tsonga
3. 2014 Tour Finals F vs Djokovic
4. 2019 Rome QF vs Tsitsipas
5. 2021 RG R16 vs Berrettini

Novak, along with Cilic, Wawrinka and Monfils at this AO. Top 5 players at their peak can still play to a top 50 level into their late 30's in this brutal bloodbath.

The 2014 YEC final vs. Djokovic is the one that Federer pulled out of before it had started, after Federer's epic semi final win over Wawrinka.

The 2012 YEC final was played. Djokovic beat Federer 7-6, 7-5.
