Fukudome has been a great addition to the Cubs lineup so far.
The Official Site of The Chicago Cubs: News: Fukudome at center of offensive surge
He was a great, patient hitter back in Japan who could use the whole field with some power.
However, I admit I did not expect him to be able to adjust to the MLB this soon, after watching Matsui (NYY) had tough time in his first year. (at the first couple of months)
Too early to tell if he keeps on hitting like this, (probably not, considering the fact that he has never experienced the long season with lots of traveling) but with the way he has been patient at the plate, I am quite impressed by his performance so far.
He does not have the speed of Ichiro, but he is a pretty good baserunner.
He does not have the power of Hideki Matsui, but I think he is capable of hitting around 20HRs/year.
He is not a great OF like Ichiro is, but he is certainly an above average OF with above average arm.
