Player: D.J. Peterson

Drafted by: Seattle Mariners (No. 12 Overall)

Position: 1B/3B

It’s hard to imagine a more consistent hitter than D.J. Peterson over the last three seasons.

Undrafted out of high school, Peterson attended the University of Mexico where he made an immediate impact as a freshman in 2011 by batting .317 with 32 doubles and six home runs. However, it wasn’t until the following season that the right-handed hitter put himself on the draft radar with an outstanding sophomore campaign.

Playing in 61 games, Peterson batted .419 with 17 home runs, a 29/33 K/BB and, more significantly, earned a spot on the Team USA collegiate national team where he continued to impress at the plate.

So, it only makes sense that the 21-year-old enjoyed his best season to date as a junior, batting .408/.520/.807 with 25 doubles, 18 home runs and a 35/46 K/BB in 55 games.

Full Scouting Report

Note: Numerical scores are on the conventional 20-80 scouting scale, where 50 is average, with the current score first and projected score second.

Hitting: 50/65

Short, compact swing; some of the best bat-to-ball ability in the draft class; strong top hand; contact-oriented bat path; pure hitter who uses the entire field; quiet load with balanced weight transfer; will hit for average at the next level; advanced plate discipline and pitch recognition; mature secondary skills; doesn’t strike out a lot; makes in-game adjustments.

Power: 50/60

Physically strong with plus raw power; line-drive swing prevents consistent utilization; drives the ball with backspin carry to all fields; could hit for more power with a deeper point of contact and better use of lower half; strong enough so that power will translate with wood. 

Speed: 40/40

Below-average runner; lacks quick feet; moves well relative to size.

Defense: 40/50

Profiles as a first baseman at the next level; can handle third base and may try to be developed there; lacks lateral movement and overall agility; makes all the routine plays; could also receive consideration as a left fielder.

Arm: 50/50

Average; can play up in games; enough for a corner position.

MLB Player Comparison: Paul Konerko

Projection: High-floor player; everyday MLB first baseman; will contend for multiple batting titles.


MLB ETA: 2015

Chances of Signing: 99.9%
