Guenther, who is a 5’11”, 185 lb. left-handed native of Atlanta, GA, is baseballamerica.com’s current number 363 overall prospect, and the 50th highest rated left-hander in the minors (as of 8/8/18).

In 13 games, including 12 starts last season between the Batavia Muckdogs and the GCL Marlins, he was 1-4 with a 3.
