And as if having to cancel a home game due to weather when you play in a dome, the Blue Jays really put their feet in their mouth when they tweeted a smug status poking fun at all the postponed games on Monday.

Six games in all were postponed Sunday, and at least three more Monday, bringing the total number for Major League Baseball games this season to 24, the highest amount since 2007 (per the AP), when there were 27 postponements through the end of April.
