Batting around

I don’t actually own that much in the way of “sports memorabilia”. Having entire gloves, bats, shoes, etc., is just too expensive. I don’t have any disposable incoming, I’m not a doctor or a lawyer, so paying hundreds of dollars for stuff is just not going to happen. I do have a signed Jim Rice jersey that Sam found for me, and a couple balls I’ve had signed in person. That was it, until today. Today I’ve added a signed bat to my collection.

So, who signed the bat…?
