Like everything else it’s a money deal. 2 games for 1 ticket price loses money. So yes, it’s gone the way of the complete game. And, as long as major league games take today, who could stay at the park for two games? I love the game, but that’s a bit long even for me.
I'll bet a twin bill in 1938 didn't take much longer than one of today's tortuously prolonged contests. Isn't three hours about normal today?
