It’s usually money that corrupts sport. But in the case of tennis, it’s also technology. As I wrote this week in the FT, there are betting exchanges with a huge range of under-the-radar matches where you can bet on set outcomes. It makes match-fixing look incredibly easy. The hope is that the very technology that allows the match-fixing can also help catch it. Readily available data means anyone with a spreadsheet skills can track what’s going on. Surely, if BuzzFeed and the BBC can do it, tennis can monitor itself properly?

Here are the stories of the week:

TENNIS SCANDAL

The story that kicked it all off: The Tennis Racket 

Is that true? One TRILLION dollars bet on sport each year?

Jon Wertheim points out that tennis’ vulnerability to corruption, match-fixing lies in economics

This is a polite way of putting it: Tennis’s watchdog seems to operate in the dark

Tennis (esp Chris Kermode) appears to be in denial 

Lawyer alert! The curious case of Fernando Verdasco’s odds 

FIFA
That other scandal. No-one writes about Fifa like Marina Hyde. Essential

ATHLETICS
Oh yes, the other other scandal. A second chance for Sebastian Coe

Coe: problem or saviour?

More Marina Hyde. Again, read it.

NORMAL TENNIS
QTWTAIY: Is Rafael Nadal in decline?

Can anyone beat Novak Djokovic?

Four of the last 5 Majors, but Serena Williams has her troubles 

Pondering a tennis landscape without today’s top players 

NFL
Good riddance! St. Louis is better off without an NFL team. The view from LA: welcome back, NFL. Welcome home, Rams. Welcome, maybe, Chargers. Now get to work, all of you.

How Roger Goodell and Cynthia Hogan are turning the NFL into a political machine

Hmm. That Al Jazeera doping report.

FOOTBALL
Jürgen Klopp is in charge of a footballing camel 

Here’s an idea for football: value for money 

BOXING
A horrific tale of a boxer post-fight.

RUGBY
Has rugby union become too complicated a game for its own good?

GOLF
Tiger Woods may not have been golf’s top earner last year, but his impact on the sport still there for all to see.

Understanding what separates Jordan Spieth from the rest.

That’s it – see you next week
