There could be some bonus to the Yankees in picking up Mark Bellhorn.
As a middle infielder, Bellhorn would know the Red Sox’ signs and indicators. So, at the least, this will inconvenience Varitek & Co. to change all their methods of communication with their staff.
And, who knows? Maybe Bellhorn knows more? Maybe he knows the best way to get David Ortiz out? Maybe he knows something the Yankees pitchers have been doing to tip their pitches (and that the Red Sox use)? Maybe Boston is stealing signs at Fenway and he knows how?
Mark has plenty of incentive to be chatty on anything he knows – after all, Boston released him. Maybe there is some payback raging inside him? Wouldn’t that be nice?
