Relief pitchers who used to pitch for the Yankees like to grow beards.

I understand that the Yankees'  grooming rules are somewhat outdated -- they were outdated 40 years ago -- but shaving every three days is not really much of a burden:

" 'This is nice, not to have to shave every three days,' Robertson recently said from spring training in Arizona, according to ESPN.com. 'I think it’s kind of ridiculous, but that was the Yankees’ rule. They wanted to have you clean-shaven. Here you can just let it grow. Obviously, they don’t want me to get it to that point. But I won’t let it get out of control.' "
