Mey

Neither Mey or Callihan are Top 30 prospects in Cincinnati’s system, according to MLB Pipeline, but they’ve earned spots on the club’s 40-man roster to protect them from next month’s Rule 5 Draft. Of that pair, Mey is the most intriguing from a fantasy standpoint as he recently was lighting up Statcast radar in the Arizona Fall League with a triple-digit fastball as one of the better relievers on the circuit. The 23-year-old righty will most likely open next season back at Double-A Chattanooga.

He topped out at 101.5 mph with his fastball. Mey walked 43 in 55 innings between high-A and Double-A this year, but he’s thus far issued just one free pass in 4 2/3 hitless innings in the AFL. Legit improvement there could make him a late-game reliever down the line.
