His regular caddy couldn’t make it so he offered a local ten times the going rate and then won. The caddy had no claim to the winnings.
Of course he didn't, nobody is saying he did.
Just as no PGA caddy has any claim to any of the winnings of his golfer, it's just standard protocol for any PGA golfer to give his caddy, no matter who it is, a 10% bonus of his winnings........Nice try
