Colorado Rockies: The top 25 players under 25 years old
19 Zach Jemiola
Jemiola was placed on the 40-man roster this offseason, which automatically accelerates where a player gets placed on the list. That’s because teams generally utilize their entire 40-man roster over the course of the season. Given that and the fact that Jemiola has already started 15 games in Triple-A, the math simply adds to you will probably see Jemiola in 2018.
Jemiola’s regular-season numbers the past two years have been just okay but the 24-year-old (on Friday) ninth-rounder from Temecula, Calif., has done admirably in the Arizona Fall League each of the past two years.
He’s not really on any prospect lists and nobody talks about Jemiola … but he can pitch and he will reach the majors. It may only be a brief time period where Jemiola is a major league pitcher but I think he can parlay a very good changeup into a solid career as a reliever.
As of now he’s unassigned in the Rockies system and it’s unclear how his 2018 season will shake out, including if Colorado choses now to convert him to a reliever.
