I agree it's unfair to call Matsui a rookie, but it's also unfair to compare Kaz Matsui to Hideki. Kaz Matsui's game is MUCH more comparable to Ichiro's.
2003 Japanese Stats
587 Abs, 33 HR, 13 SB (33 the year before), .305 AVG (.309 Career)
My Guess at 2004
15 HR, 25 SB, .290 AVG...RBI/R varying for team.
That's pretty good, IMO.
Ichiro's doing pretty good for himself and Matsui did pretty well for an "inaugural" season.
Zack Greinke...the next Greg Maddux. LOOK IT UP!
For what it's worth.
