"It's really exciting for our promoters. It gives them a little bit more strength when they're trying to put Joseph in the ring with world-ranked fighters.
"I can see us being ranked in the top 10 by the end of the year," Barry said.
Parker had a cortisone injection yesterday to treat a minor shoulder problem but the South Aucklander was passed fit to meet Williams at the Trusts Arena. Barry said the ongoing ailment wouldn't rule him out of headlining December's Fight for Life.
No opponent has been confirmed for that but Barry said Parker would be busy in coming months. "There are fights out there for us ... exciting fights, ranked fights. But the politics are becoming more and more apparent."
But before the 10-0 Parker can worry about 2015, he will need to beat 42-year-old Williams (36-13-2). Parker's PABA and WBO Oriental heavyweight belts will be on the line against Williams.
