 On the line was the WBO interim title, held by hard-hitting slugger Michael Katsidis, as well as a chance to fight for a full world title later in the year.At the opening bell, Mitchell looked to establish his jab and keep Katsidis at bay.In the first two evenly split rounds, the occasional flurry of hooks from a highly aggressive Katsidis was enough to make Mitchell fight consistently on the back foot in an attempt to keep out of range.
