Heller leads High-A Salem with a .466 on-base percentage and .596 slugging percentage through 15 games. He's a 40th round draft pick in 2012 out of Division III Amherst College.
Heller's an under-the-radar minor leaguer who has emerged as the biggest surprise in the organization in 2014. At one point, Heller had stroked an extra-base hit in five straight games. He's been a much more patient hitter, who's swinging only at strikes, according to High-A Salem manager Carlos Febles.
