Jake Lamotta and Fritzie Zivic fought each other 4 times . Jake won 3, A 10rds u dec 14th Jan 1944. A 10rd split dec 12th Nov 1943. A 10rd split dec 10th Jun 1943. Fritzie won 1, a 15rds split dec 12th July 1943. I know why the win for Zivic was over 15rds ,though it was a non title fight. Do you ?
zivic and lamotta gained their 15 round stature because of the unpopular decision which favored the new york fighter in their first fight over the ten round rout last june. http://news.google.com/newspapers?id=0bI0AAAAIBAJ&sjid=_2kDAAAAIBAJ&pg=5814,2329330&dq=jake+15&hl=en
