Earlier this month, the Arizona Diamondbacks named top prospect outfielder Alek Thomas to their active roster. Thomas, who attended Mount Carmel High School in Chicago, has a wRC+ of 133 and a 13.7% strikeout-to-walk ratio. Thomas’ impressive rookie season should lead to a regular starting job in the majors for the first time. In his first full-season with the D-Backs, Thomas compiled eight doubles and three steals in 101 at-bats.
