Ichiro Suzuki, Akinori Iwamura & other NPB minor league stars

Ichiro Suzuki is some day going to be the first player to begin his career in NPB and end up in MLB’s Hall of Fame. Akinori Iwamura won’t make it, but people familiar with his career in Japan know what a good ballplayer he was.

I recently re-added the minor league batting and pitching data from 1991 to 2001 to my data base — I lost my originals about 20 years ago in a hard disk crash — and asked which under-20 minor league hitter (minimum 200 PA) had the best seasons with offensive winning percentages over .700.

  1. Ichiro Suzuki (19.2 years old), Orix 1993, 214 PA, .883
  2. Akinori Iwamura (18.9), Yakult 1998, 430, .810
  3. Seiji Uebayashi (19.4), SoftBank 2015, 332, .799
  4. Akinori Iwamura (17.9), Yakult 1997, 297, .785
  5. Ichiro Suzuki (18.2 years old), Orix 1992, 270, .784
  6. Kensuke Kondo (19.4), Nippon Ham 2013, 227, .781
  7. Tomoya Mori (18.4), Seibu 2014, 257, .755
  8. Hisashi Takayama (19.1) Seibu 2001, 343, .708





Suzuki took a nice jump forward in 1993 and the next year took another when he won the first of his three straight PL MVP Awards. Most of the rest of the guys you know, although some of you may have forgotten Hisashi Takayama. He was an outfielder without outstanding speed or power and had one chance to play regularly at the age of 28 in 2010, when he played quite well, but was otherwise a guy on the fringe. Takayama’s minor league season at the age of 20 was the 10th best by a player aged 20-21 since 1991, so it’s fair to say Seibu REALLY missed the boat on him.

When Hisanobu Watanabe was promoted from farm manager in 2008, Takayama was one of the guys he gave a shot to in the spring, but at the age of 26 he needed an ally and didn’t have one. Then batting coach Hiromoto “Dave” Okubo, wasn’t a fan of Takayama’s and insisted on keeping hustling and likeable-but-underqualified Kenta Matsusaka as his right-handed-hitting platoon outfielder.

Uebayashi, who is mentioned here, is someone who lacks some plate discipline but who does everything else fairly well but has yet to break into SoftBank’s regular lineup. Had he played for Nippon Ham, however, like Kensuke Kondo, he’d no doubt have a job by now. Mori, it seems is caught in a crunch as well, he’s probably a better hitter than the other guys who are taking his playing time, but he needs to go out and prove.

The best minor league season for a player aged 20 was by Lotte’s Toshiaki Imae in 2004, a year before he became the Marines’ regular third baseman for a decade. At age 21, the best was by Ken Suzuki of the Seibu Lions in 1991. Suzuki went on to be a DH-third baseman for the Lions pennant-winning teams in ’97 and ’98 and a corner infielder with Yakult in 2001.
