On both those occasions a sluggish start had proved costly and so the emphasis this time was on taking an assertive approach from the word go.
"We wanted to make an early statement. We knew that Boobyer's greater experience would make him more dangerous the longer the fight went on," Baron said
Hopman carried out the game plan to perfection, using his technical skills to take the battle to Boobyer and eventually working himself into a position from where he could strike the winning blow.
"He fought very intelligently, he picked his shots well and never really looked in any trouble," Baron said of Hopman.
"He did exactly what we planned, it was impressive."
Hopman will fight for New Zealand at the world Muay Thai championships in Thailand next year but may still have a couple more professional bouts before then.
