The Pirates filed an official protest with Major League Baseball over Jerry Meals’ call at the plate. That’s nice and everything, but it should be and will be dismissed out of hand by Major League Baseball, because it is an impermissible protest under the rules. Here’s Rule 4.19 of the Official Rules:
Each league shall adopt rules governing procedure for protesting a game, when a manager claims that an umpires decision is in violation of these rules. No protest shall ever be permitted on judgment decisions by the umpire. In all protested games, the decision of the League President shall be final. Even if it is held that the protested decision violated the rules, no replay of the game will be ordered unless in the opinion of the League President the violation adversely affected the protesting teams chances of winning the game.
Whether a tag was applied or not is a judgment call, so the protest is invalid.
Wanna make the Pirates fans really mad? Fine the team for the knowingly impermissible protest!
