For a little bit of a last look at the Arturo Gatti vs. Carlos Baldomir I turned to Title Bout Championship Boxing 2 (the best boxing simulator available).
I ran a simulation of the bout 10 times, watching the first and just checking the results of the remaining 9.
In the 10 fights Carlos Baldomir won 9; 5 by UD, 2 by TKO and 2 by MD. The 5th fight of the series went to Gatti by UD.
While this doesn't mean anything in the real world last weekends fight ended with a seventh round Mosley TKO when I simulated it, and the weekend before a simulation of Spinks/Karmazin resulted in a close decision win for Spinks.
