He edged home a hard-fought decision win in Japan, despite Willibaldo Garcia's late rally for IBF junior bantamweight honors on June 6.

Jason wants to be a champion again and this time, the chance to do so simultaneously alongside his sibling.

"That's what gets me out of bed, the reason I'm training hard and making sacrifices every day," Moloney (29-4, 20 KOs) told The Ring.

"The goal has always been for me and Andrew to be champions at the same time, I'm working bloody hard to make that happen." Moloney was thrilled to see his brother get over the hump, having fallen short in three battles with Joshua Franco as well as three-weight world champion Junto Nakatani in previous years.

"It's hard to put into words how happy I was when Andrew became champion," he said. "I was more emotional when he won than my own world title.

"He has truly done it the hard way; probably been one of the world's most unlucky fighters over the past five years with all the setbacks and bad decisions he's copped. There were times when he nearly gave it away. To train with him every day, see him persevere and finally become champion was truly special."

Moloney watched Riku Masuda and Daigo Higa contested the WBA 'regular' bantamweight title on July 20.

Both had their moments, though Masuda (11-1, 9 KOs) continued his excellent run to win a 12-round split decision.

"It was a really good fight. The level of boxing in Japan at the moment is incredible, lots of good fighters and great fights," he said.

"I thought Masuda won in a close, competitive fight. I always like the aggressor, so liked Higa's work but thought Masuda just did enough to win."

Masuda is directly in the veteran's crosshairs after that result and despite recently joining the Zuffa ranks, he doesn't believe his promotional status would impact him facing the 28-year-old nor any other champions.

"I would love to fight Masuda, especially now that he has a belt," the 35-year-old said.

"I don't believe that signing with Zuffa would cause any issues. They have just made Ryan Garcia-Conor Benn; I think any fight is possible especially if it's a fight fans want to see."
