Long, a 12th round pick by the Reds in the 2013 draft out of high school, has shown some nice development in power since being selected. In the rookie leagues, his OPS numbers were just .654 in 2013 and .424 in 2014. However, that jumped to .836 in 2015 after a promotion to Low-A Dayton. Much of that was due to six home runs and seven doubles in 152 at bats. He also boasted of a K/BB ratio of 31:18 that season. In 2016, he got off to a quick start in his second season with Dayton, hitting .264 with a .793 OPS in his first 52 games.
