UPDATE @ 7:00 PM- The Cubs did sign Juan Yasser Serrano to a 250K contract. It is now also known that he is 22 years old.
First reported by cubanballplayers.com, the Cubs are close to signing Juan Yasser Serrano to a 250K contract with the Cubs. MLBTR is saying that he has in fact not signed yet but his representatives and the Cubs are in discussions. I do not have a ton of information on Serrano except he is a 20 year old right-handed pitcher and that he throw pretty hard hitting 93 during his tryout for the Cubs.
I will have more on this as it becomes available.
