Shaffer (b. 1991) played in the majors in 2015 and 2016 for the Rays. He was a first round pick (25th overall) by the Rays in the 2012 June Amateur Draft out of Clemson. Before that, he went to Providence High School in Charlotte. He had 26 hits, 5 home runs and a .213 batting average.
I mailed to Shaffer on August 4 and got the cards back on September 3, for a 30-day TAT.
