2018 Low 80 70: All-star CF No
Makeup

Appears to enjoy the game, plays with confidence, looseness. Late in AFL, was losing approach to sell-out for power, but nothing of concern

Tool Future Grade Report
Hit 60 High hands (above ear) in set-up. Moderate leg kick with big forward stride into wide stance at max load. Load is short and quiet, sets up slight upward launch angle. Stays balanced, in sync through maxed-out extension. Excellent, explosive hip rotation, plus-plus bat-speed and plus barrel control all result in consistent, all-fields, hard contact. Stays closed, let’s ball travel deep and demonstrates solid approach most of the time. Can get over-aggressive early in counts. Swing has some length and barrel drag, exposing Acuna to plus inside fastballs. Bat speed and barrel control compensate. Swing-and-miss becomes moderate concern when selling out for power.
Power 70 Wrist strength and quickness is major asset. Generates additional power via leg lift. Short load, wide stance, and launch angle allow him to tap large portion of raw power in games. HR pop to all fields but in games mostly pull side. Will sell-out in hitters counts despite not needing it, as power comes easily with quiet swing. This adds to swing-and-miss.
Baserunning/Speed 55 4.23 home to first. Faster underway with longer strides. Can steal some bases. Additional weight could slow him down as he matures.
Glove 55 Demonstrates good reads and solid first step; gets to the gaps and balls in, less confidence tracking back. With age, could slow down and move off position but will play to above average into mid-20s.
Arm 70 One-hopper on line from RF warning track. Throws to correct base/target with accuracy.
Overall

Impressive player ready to contribute now despite youth; eventually fits in three-hole with power/hit combo. Will stick in CF; if moves to RF, more than enough glove and arm to handle position. Bat is elite. Player projects to hit for 30 HRs with high average and ability to steal some bases given current development and age. Sky is limit talent-wise, especially if player maintains body and continues improvement in CF. OFP is .300 hitter, 30 HRs, 20 SB in CF.

Risks are limited, although Acuna’s swing can get long when he’s trying to crush everything, dragging the barrel and exposing himself to quality pitches; when he maintains his approach, bat is premium. Could move to RF, but bat will play there.

Physical/Health
80-grade athlete with plus speed and strength. Makes physical attributes of the game look easy. Loose, fluid, long strides. Still learning to control body. Knows he has speed and ability and shows it off in field and on bases. Frame carries strength but is lithe, expect to maintain athleticism as he ages.

mid-2019 Moderate 70 55: Above-average starting center fielder No
Makeup

Plays loose; aggressive; high energy. Reportedly takes instruction well.

Tool Future Grade Report
Hit 50 Wide stance, modest leg-lift into forward stride. Short load, modest shoulder dip creates slight upward bath path leading to line drives, flyballs. Keeps bat head in zone. Full extension. Elite bat speed and wrist strength, uses loose hands to get barrel to ball, cover outer half. Will open early, shoulder dip lower when not going well. Will expand zone on breakers. Plate discipline, feel to hit stilll raw. Swing is good enough with bat speed and barrel feel to play to average with modest plate discipline development.
Power 60 Shows 7 raw power selling out in BP. Bat speed, strength, and launch angle project to plus game power. Has power to all fields, mostly pull in games at present. Grade projects further development in plate discipline, feel to hit to land in FB counts.
Baserunning/Speed 60 Home to first 4.18-4.23. Faster underway, long strides, closing speed. Aggressive runner, big leads. An asset on base paths.
Glove 50 Makes plays with legs. Poor reads and routes, closing speed makes it work. Doesn’t seem to easily pick the ball up off the bat. Grade projects development but moderate risk that he moves to corner.
Arm 60 Easy motion, average release, good carry
Overall

Harrison has rawness but shows the ability to convert plus athleticism to baseball skills. His athleticism allows margin for error, but the player has developmental hurdles remaining to reach his realistic role. Defensively, if routes and reads do not improve, anticipate a move to RF. At plate, plate discipline development is critical to everyday role, allowing 7 raw power and speed on bases to play. Harrison has incredible upside if he hits all of his development hurdles. Project to be good enough in CF to stick there where his power will be an asset. Given athleticism, make-up reports, prior development, confidently project continued improvement at plate and in all around game. Risk/variance still high in hit tool until he shows he can make enough good contact above A-ball.

Soft body, thick middle, strong. Weight maintenance presents long-term challenge. He has some athleticism and runs better than his frame suggests he should but history of body type in MLB not good. Footwork has improved since 2016 look. Average flexibility.

late 2019 High 50 45: Platoon 1B No
Makeup

Strong in-game instincts. Despite size, game does not speed up on him.

Tool Future Grade Report
Hit 60 Sets up with hands at letters, wide stance. Slight leg lift into short stride. Moderate load, hands moving up and back, creating slight angle to swing path (line drives) that keeps barrel head in zone for max time. Plus bat speed. Has excellent plate discipline and barrel feel with all-fields approach.
Power 50 Has 7 raw power but game swing is level, geared for line drives, frequent contact. Will pick spots to power up pull side. With some adjustment should get to average. Could be candidate to open up as he progresses.
Baserunning/Speed 30 Home to first 4.50. Liability. Faster underway (will get extra bases from home), but clogger in most base running situations. Has good base running instincts, doesn’t run into outs.
Glove 40 Has fringe-average footwork, average when charging. Fringy moving laterally. Hands average when fielding ground balls; scoops well; average stretch.
Arm 55 Limited look. When shown across infield was on line was above-average velocity.
Overall

Player will need to maintain weight and continue developing at 1B to have an MLB role. He projects to below-average at the position and will need his bat to play. As a hit-before-power 1B, he is an unlikely candidate for an everyday role, but hit tool has upside and raw power is still in there despite swing path. May fit well as strong-side of platoon, where he should tap into more of his huge raw power. Player hits too well at his age not to get chances, but body concerns and lack of game power present risks.

Physical, looks thicker than listed weight. Strong, thick lower half. Broad shoulders and strength in upper body and arms. With age, I expect player to add more weight, fill out to a corner outfield body

2019 Moderate 55 50: Average regular RF No
Tool Future Grade Report
Hit 50 Noisy set-up: during windup, player shifts set up with weight to back foot, front leg fully extended on toe; hands at shoulders. Toe tap w/ moderate stride; short load. Keeps weight back as long as possible, stays upright. Swing is short with plus bat speed and good hip rotation. Hips drift, barrel drags. Player has solid pitch recognition skills with some feel to hit and ability to lay off off-speed. Plate discipline is plus. Average bat speed. Bat-to-ball skills and feel to hit help compensate for issues with swing mechanics.
Power 55 Currently 55 raw/50 game, projects to 60 raw power, will play to 55 in games. Swing has leverage and bat path to hit balls in the air, but player is selective and often sticks to line drive approach. Shows both level and elevated bat path in BP and games. HR power pull side at present, looking to line drive away.
Baserunning/Speed 50 4.27 home to first time. Only average first step quickness but runs better underway. While slightly above-average now, will eventually settle in to average speed. He could steal some bases but is not a true burner.
Glove 50 Routes in need of refinement, lacks quick first step. Does well charging the ball and moving in; less confident moving back. With average speed and more reps, projects to average in outfield corner; lacks the range to play CF.
Arm 55 Arm is strong enough for right field; some length to throwing actions but nothing of overwhelming concern.
Overall

Player has tweener risk, but future defensive home is in a corner. RF is the best fit given above-average arm and average range at the position. Player does enough good things at the plate to carve out an average regular role, with his best attributes being a patient approach and good eye. There’s just enough of the hit/power combo with average defense to nail down a role as a regular RF.
