While these are a few years old now, below are Ji-Man Choi’s Baseball America Prospect Handbook write-ups while in the Seattle system. The now 26-year old Choi ranked in the Mariners top 30 prospect lists in both 2014 and 2015 (#25 and #29 respectively)... 2014 Choi had a breakout season in 2013, starting at high Class A High Desert, making stops at Double-A Jackson and the Futures Game along the way. He ended the year at Triple-A Tacoma. All of that happened while he was making the conversion from catcher to first baseman, and he wound up being protected on the 40-man roster in November. Choi made a splash in 2010 when he was the MVP of the Rookie-level Arizona League, but his career stagnated until he became a full-time first baseman and also put together a better plan of attack in the batter’s box. Already possessing a good eye, Choi has become even more selective and instead of spraying line drives to the gaps at his best. Choi fits the second-division regular description and is in an organization that continues to chase power at first base. 2015 Choi always has been known as a hit-first player—he moved off catcher to first base in 2011–whose lack of power limits his chances of being an everyday big leaguer. So when hit with a 50-game suspension early in 2014 for using a performance-enhancing substance, he faced further skepticisim. Upon his return from his suspension, Choi didn’t really assuage that criticism by slugging .392. He is a pure hitter who can line the ball to all fields with a short, direct, lefthanded stroke, but he doesn’t have much natural loft in his swing. His best-case scenario is as a James Loney-type offensive first baseman, but as a fringe-average defender, he lacks Loney’s defensive value. The Mariners tried Choi in left field, but he’s not a viable option out there.
