The Seattle Mariners may not have the flashiest of farm systems, but Tyler O’Neill represents a truly exciting prospect. O’Neill spent last season with the Bakersfield Blaze, and he was the co-winner of the Mariners Minor-League Player of the Year in 2015.
Originally selected in the third round of the 2013 draft, O’Neill began his professional career with the Mariners’ affiliate in the Arizona Rookie League. He did a nice job in the desert, slashing .310/.405/.450 across 116 plate appearances. O’Neill also hit 1 home run and drove in 15 runs through 28 games.
