On Sept 30th, the Blue Jays clinched the divisional title in the first game of a double-header. There were many shots, in the last few minutes of the first game, of players in the dugout waiting to celebrate. One of them was wearing what appeared to be a toque or brimless cap. It was blue and had a Blue Jays logo on it. Later, he was celebrating on the field with a GoPro over this hat.

A little twitter research reveals that it was David Price, and that he had the hat custom made. I would have imagined that brims were not optional. Are there rules about caps and hats? Do they perhaps only apply while a player is on the field?

While there are no specific rules in MLB OBR about caps and hats, rule 3.03 (a) requires all players to wear the same kind of uniforms. This includes the same style of cap, as well.

3.03 (a) All players on a team shall wear uniforms identical in color, trim and style, [...]

Rule 3.03 (c) goes on to explicitly disallow any player not wearing the team uniform to participate in the game:

3.03 (c) No player whose uniform does not conform to that of his teammates shall be permitted to participate in a game.

Two questions arise from that:

  1. Who is considered to be a player?

  2. What is considered to be participating in game?

While the rules don't give a clear answer to any of those two questions, let's assume that David Price was neither considered to be a player in this instance* nor was he considered to be participating in the game. The question that comes up next would be:

  1. Why was he allowed to be in the dugout in that case?


BENCH OR DUGOUT is the seating facilities reserved for players, substitutes and other team members in uniform when they are not actively engaged on the playing field.

In this instance he should be considered an other team member and this definition hints, that all team members should wear the same kind of uniform, as explicitly required for players in rule 3.03 (a).

This leads me to conclude, that David was - by the rulebook - not allowed to wear his custom-made hat. But then again, there is always rule 8.01 (c):

8.01 (c) Each umpire has authority to rule on any point not specifically covered in these rules.

* On September, 30, when the Blue Jays won their division, they played two games. David didn't appear on any of the two lineup cards (Game 1, Game 2), so he was not eligible to come into the game. In this case it is fair to assume, that he didn't count as a player.

    interesting. But many players wear coats in the dugout which I presume they would not be able to wear on the field. In theory, had he been subbed in, might he have had to switch to a proper hat? Commented Oct 3, 2015 at 11:44

    Yes, if he was to come into the game - which he couldn't because he wasn't initially listed on the lineup card as a substitute -, he would have to wear a proper hat. Proper beeing defined by what the rest of the team wears. If they all have the same hat, then it could also be the one that David had put on. Commented Oct 3, 2015 at 15:53
