The Commissioner decides if games will be canceled, delayed or shortened due to inclement weather and/or field conditions. The commissioner reserves the right to cancel all games if there are weather or safety concerns. Umpires cannot cancel a game due to weather or field conditions once a game has started without the consent of the two managers. All parties should check weather radar and use common sense in deciding if a game should be canceled, delayed or continued. If lightning occurs, the game will be delayed for 15-minutes, but the game clock continues as no inning shall start after 2H-30M.
Playing, coaching or umpiring baseball games for a number of years should lead to knowing all the ins and outs of the rule book, right? That doesn't seem to be the case for everyone given the amount of questionable calls. ESPN's baseball crew teamed up with a rules expert to create and administer a quiz to current MLB players, managers/coaches and the media. The results were less than impressive. Do you know the game better than the people who live it every day?
