Emojis on baseball bats to send messages

There is a certain issue arising with the bats of Bryce Harper, who has placed an emoji on the end:


For those of you who aren't hip with Millennials, it carries two meanings in this case. The obvious is that it's the number 100 and Harper's next career home run will be No. 100.

The less obvious, at least for those not up on their emojis, is that the symbol in question means "keep it 100." That phrase means "to keep yourself real and true, to be honest and stick to the way you are, no matter what any one else thinks," according to Urban Dictionary.



BUT


Major League Baseball implemented new rules just prior to the start of the season stating that bat decals could only contain a team logo or the player's number. This appears to be in violation of that rule.
