Wow... Plot hole!
At the end of the movie, before the final putting, they were tied. Judge sinks his but his partner misses. Ty misses. If the kid misses his shot, he and Ty lose, as Ty says.
Kid sinks his putt and then Rodney/Ty celebrate the win.... Except they were one stroke behind, so that shot would mean the game is back to a tie.
Liked the movie, but they should have paid attention to that.
