The 2015 season was the organization's first year as a member of the rookie ball-advance Appalachian League. Created as a means to split the more advanced rookie-ball players from the GCL Yankees, make a buffer before A-ball, and make enough room for the influx of international talent signed in 2014, the Pulaski Yankees ended up having an impressive year. They led the league with a 45-23 record, only to be eliminated from the postseason too soon for their talent level. Pulaski ended up being an offensive juggernaut with a few of their pitchers having great seasons as well in order to set up one of the more dominate teams in the entire Yankees system.
