Brinson has loud physical tools: plus raw power, plus speed, plus arm strength, and the ability to play center field despite mediocre instincts. He didn’t hit for as much power as was expected at hitter-friendly Colorado Springs in 2017, but scouting reports on the raw power, and Brinson’s ability to get to it in games, remain strong. Provided he’s able to make continuous adjustments — and he’s exhibited the ability to do that on his ascent through the minors — Brinson has 25-homer potential. He has had several soft-tissue, lower-body injuries during his career, including multiple hamstring issues, one of which ended his 2017 season. He’s still a plus runner underway but doesn’t reach top speed as quickly as he once did.

This is what it looks like when things start to click on the baseball field for a premium athlete: a .272/.350/.481 line split between two levels, 51 extra-base hits (including 21 homers), and 27 bases stolen at a 87% success rate. Harrison has always had late-bloomer traits. He was a multi-sport stud — not multi-sport athlete, multi-sport stud — in high school and only committed to baseball full time after turning pro. In parts of three pro seasons entering 2017, Harrison missed time with a hamate fracture and broken leg, which prevented him from getting the reps he needed and diluted the way his tools looked on the field when he was.
