I've been thinking a lot about hockey, my other favorite sport, and specifically the fact that most hockey players imported from other countries (I'm thinking specifically of Pittsburgh's Evgeni Malkin last season) start strong but struggle because the American season is more demanding than anything they had ever trained for or played in before. So I went to the numbers, mostly to give a recommendation on what to expect from Kosuke Fukodome and Hiroki Kuroda at season's end. Here's what I found:
Hitters: I went to the most memorable of Fukudome's predecessors in order, starting - of course - with Ichiro. He came to America in 2001 and was a national sensation, hitting .350 and slugging .457. He hit 8 HR, drove in 69 runs, scored 127 runs, and stole 56 bases. Since then, he's been a great player, but he's never stolen more bases, scored more runs, driven in more runs, or hit for a higher slugging percentage (and he's only bested the average once and the HR thrice). He has been a great player since, but his first season was actually his career best in just about every category. Hideki Matsui, the next sensation, had his worst season in his first year in. His OPS+ was 15 points lower than his next-worst year, and his power numbers were way down from other years. Kazuo Matsui, he of the same last name, played better in his first year here than in the next two. He finally got untracked in Colorado last year. Kenji Johjima only has two full seasons catching in Seattle, but each offensive statistic was a little worse in 2007 than it was in 2006.
What does all this mean for Fukudome? Well, unfortunately, it means there isn't a great trend to follow. But I see Hideki Matsui as a different type of player than Ichiro, Kaz, or Johjima, because his game was based on hitting for power. Fukudome seems to compare in playing styles with Ichiro, and I think he could easily hit well for an entire season.
Pitchers: The classic pitcher case is Hideo Nomo, who came over all the way back in 1995. He took baseball by storm with his unusual delivery, and like Ichiro, he never equaled his 2.54 ERA or 236 strikeouts, but he had excellent seasons in his career. There isn't as much data on pitchers; I want to look at Dice-K but he's only been here a year. Takashi Saito, in two years, has experienced two successful seasons. Though his strikeouts went down in year two, his ERA also went down by .50, so I can't call one season much better than the other.
What does this all mean for Kuroda? Very little. I'd love to say he will imitate Nomo's success in his first year, but I think much of it was due to the fact that US hitters had never seen Japanese pitchers before. In the NL West, where most hitters have faced Takashi Saito, Kuroda will derive little of that advantage.
So, in the end, what I've found may not seem like much. Returning to my gut-check feeling, I like Fukudome to keep hitting well all year. He's in a great lineup that should allow him to see good pitches all season long, the warm weather can only help a guy whose game is based on speed, and I think he's shown in the very small sample that is this season that he will have no trouble figuring out American pitching. Training and endurance, the main issue for "imports" in other sports, seems to be a non-factor for Asian ballplayers coming to America. As for Kuroda, I don't expect him to reach Nomo-like success. He's a little tougher to predict, though the same statement on endurance applies. Hopefully, in a few more years, the picture will expand and I can make better predictions. Until then, treat them like typical players. Watch for injuries, bench them during slumps, but look for them to have excellent seasons at year's end.
