Before the start of the series, Parx had offered a proposition wager on one team to win the series. But if each team won the same number of games, the bet would be void and the bettor would get back the money from his original wager. This is fine for a longer series or — for that matter — a hedge in case something wild happens during a 3-, 5- or 7-game series. Not a 2-gamer. But that’s only part of the issue.
