Unfortunately I don't know where you can find it on net.
However I re-watched this fight on Video Tape couple times. All I can tell you, Martinez was more accurate, Williams more volume. Martinez seems to land more clear shots but did not push himself to the end. Williams did all he can. As for the winner Martinez by one or two points IMO. Draw would be OK too. So all in all, judges like more Williams. The only one reason I would like Williams in this fight - he gave it all unlike Martinez. Martinez looked like he might quit on his stool in the middle of rounds even though he clearly has enough to go full distance.
This is my opinion about this fight, obviously might be subjective but this is what I saw after watching this tape couple times.
