Hayes, 19, is batting .269/.325/.399 with six home runs, 31 RBI and six steals through 55 games for Low-A West Virginia.
The teenager has not been overwhelmed at this level. The son of former big leaguer Charlie Hayes was a first round selection in the 2015 draft, and is expected to play the same position as his father. The younger Hayes is still a few years away from making an impact for the Pirates, but his future is bright, and his power is expected to develop as he matures.
