Mummey (b. 1989) was a 4t round pick by the Orioles in the 2010 June Amateur Draft out of Auburn University. He played in the minors from 2010 to 2014, all in the Orioles system, reaching High A. He had 170 hits, 11 home runs and a .237 batting average.
I mailed to Mummey on October 19 and got the card back signed on December 13, for a 55-day TAT.
