11th inning to start with 2 on in World Baseball Classic

Asinine. That is not the way the game is to be played !

The changes sound logical. As the regular season begins after the WBC is finished, it saves wear and tear on the pitcher's arms. But despite the changes, if a game is still tied after more innings, say 15 or 18 innings, then what? I forget ... is there a certain number of innings that can be played before a tie is called like in Japanese pro baseball? Or is there no tie?

Sure, change the rules because the population is limited attention span.
