As you can see from the dialogue, the ending still doesn't make sense. How can you do a double-or-nothing bet if the match was tied going into the 18th hole?

Gentlemen, this match is all even.
Final hole. Doctor, you are away.
Spaulding, this calls for the old Billy Baroo.
This is a biggie!
Don't let me down, Billy!
Forty thousand dollars...Billy!
I knew you'd do it!
"Silver wings upon their chest...
"...these are men, America's best."
Don't worry about this one.
If you miss it, we lose.
Hey, Judge! Double or nothing
he makes it!
Eighty thousand dollars!
What's that, Judge?
You're on!
We're waiting!
Noonan...you can do it!
You lose it, buddy!
Fore!
It's a birdie!
All right, Smails, that's grand.
Now fork it over!
I'll give you nothing!
Absolutely nothing, you understand!
