LAS VEGAS – George Kambosos Jr. had his moments while sparring recently with Manny Pacquiao.

The unbeaten Australian lightweight prospect was even more successful Saturday night against another Filipino southpaw. Sydney’s Kambosos beat Ray Perez by unanimous decision in an eight-round, 135-pound fight on the Manny Pacquiao-Adrien Broner undercard at MGM Grand Garden Arena.

All three judges – Tim Cheatham, Patricia Morse Jarman and Ricardo Ocasio – scored each of the eight rounds for Kambosos (16-0, 9 KOs). He won by the same score, 80-72, on all of their scorecards.

The 25-year-old Kambosos’s hand speed and accurate right hand was too much for Perez (24-11, 8 KOs), who regularly paid for engaging Kambosos inside. Perez clipped Kambosos with a short right hook near the end of the second round and had some success in the ensuing rounds once he started fighting from a right-handed stance.

Overall, however, Perez had difficulty fending off the accurate, active Kambosos and clearly lost.

The quicker, more athletic Kambosos landed numerous straight right hands, right uppercuts and often got out of harm’s way before Perez could counter him. The 28-year-old Perez displayed toughness, but couldn’t get into a rhythm against a younger, better boxer.

Kambosos spent the previous few weeks helping Pacquiao prepare at Freddie Roach’s Wild Card Boxing Club in Hollywood, California, for his main event Saturday night against Broner.
