Since I don't get to watch K-1 I haven't seen him other than videos from the web but his record is impressive to say the least:

Result Opponent Method Event Title Date
Win B.J. Penn Decision (Unanimous) K-1-Hero's 1 3/26/2005
Win Sam Greco Decision (Split) K-1 MMA-ROMANEX 5/22/2004
Win Michael McDonald Submission (Guillotine Choke) K-1-Beast 2004 3/14/2004
Win Rich Franklin TKO (Punches) Inoki Bom-Ba-Ye 2003-Inoki Festival 12/31/2003
Win Stephan Bonnar TKO (Cut) JF 1-Jungle Fight 1 9/13/2003
Win Kengo Watanabe Decision (Unanimous) NJPW-Ultimate Crush 5/2/2003

That's a pretty good list of opponents with all W's ... what's the scoop on him??
