Papelbon (b. 1983) was a 19th round pick by the Cubs in the 2006 June Amateur Draft out of the University of North Florida. He played in the minors from 2006 to 2010, all in the Cubs system. He reached AAA in his time in the minors. He had a record of 22-15 with 338 strike outs and a 3.47 ERA.
He is the brother of former Red Sox closer, Jonathan Papelbon.
I mailed to Papelbon on May 24 and got the cards back on June 1, for an 8-day TAT.
