Here is the article at the Chicago Tribune: Click!
Here is a brief paragraph in the article:
The pitcher they're most interested in is Ken Kadokura, a 35-year-old right-hander, and they also had a tryout for 34-year-old left-hander Shigeki Noguchi. The Yomiuri Giants released both veterans after the 2008 season.
Personally, I just see this as a move to try to add more players to ease Fukudome's transition from the Japanese League to Major League Baseball. This also indicates that the Cubs haven't given up totally on Fukudome as an effective hitter.
