PICK ANALYSIS: The Mariners picked D.J. Peterson in high school. They wanted a power bat with this spot and Peterson offers one of the best all-around bats in the draft. While there are defensive questions, his bat will play anywhere.
SCOUTING REPORT: The Mariners drafted Peterson in the 33rd round out of high school in 2010, and he turned down a six-figure offer to head to New Mexico. That decision will paid off. Peterson figured to go in the top half of the first round as one of the class’ best all-around bats.
Scouts gush about his hitting ability. He has short, hitter’s arms, tremendous bat speed and strength, and always hits the ball on the screws. His hitting mechanics are sound, with quick, strong hands, and he shows the ability to make adjustments on the fly. He has keen pitch recognition skills and already has a pro approach to his at-bats. While New Mexico plays at an elevation higher than Coors Field, scouts say Peterson’s power is legitimate. That’s good because defense will never be a big part of his game. He is a below-average runner with an above-average arm. He moves well for his 6-foot-1, 205-pound frame and should get a chance to stick at third base, but he’ll likely wind up in left field or first base. Peterson’s bat should allow him to move quickly.
WHERE HE FITS: Peterson’s bat is special. One scout this spring said it’s the best swing he’s seen in 25 years of coaching and scouting. The Mariners system is loaded, but Peterson is easily in the top four prospects for Seattle and has Paul Konerko upside.
