In the 1905 World Series, Giants utilityman Sammy Strang had one plate appearance where he struck out. This entitled him to his complete share of the gate, the equivalent of around $33,000 today. Over a century later, another sportsman would only appear briefly yet cause a great amount of money to shift hands.
On January 9, 2022, in an otherwise undistinguished game between the Golden State Warriors and Cleveland Cavaliers, an injured Draymond Green made a ceremonial appearance at tipoff to be able to “start” with returning Klay Thompson before immediately fouling an opposing player and leaving. The result was that those who bet the under on his player props triumphed. However, this was not an issue of just him getting hurt quickly. His plan was announced shortly before the game, creating a window for people for hammer said unders.
It was an example of what Jason “Spreadapedia” Weingarten rightfully summed up as “One word: Greed”. And it demonstrates what I consider the odiousness at both sides of the sports betting industry. A big reason for the outsized losses is the presence of the “Single-game parlay”, where you can make parlay/accumulator bets (ie, you get a bigger payout, but they all have to win), on different elements of one game. Parlays are notoriously more profitable for the books overall, which is why they push them. However, the nightmare scenario is that all those blockbuster parlays (usually strings of giant favorites) actually hit. So yes, the books were playing with fire, and got burned.
However, I also have surprisingly little sympathy for the people who tried to take advantage of the error and got restricted for it. One of the secrets that a lot of casual observers don’t know are that many, if not most pro bettors (Protip: DO NOT BE A PRO SPORTS BETTOR) are people who pounce on slow/off/etc… lines instead of being super-handicappers. It’s why their complaints about being constantly restricted have fallen on deaf ears to me. And for something so obvious, I’m extra-uncaring about their “plight”.
