Demeritte was drafted by the Rangers out of high school in Georgian in the first round of the 2013 draft, 30th overall. He was sent to the Rangers Arizona Rookie League squad, where he thrived, hitting .285/.411/.444 with 4 home runs and 5 stolen bases in 175 plate appearances with a 16.6% walk rate and a 28% strikeout rate.
The Rangers aggressively promoted the 19 year-old to full-season ball with low-A Hickory of the South Atlantic League in 2014, and Demeritte had major flashes, though he showed some big holes in his swing as well and some definite raw-ness to his tools.
