The Mexican boxer Andy Ruiz hasn't been impressed with the form of Joseph Parker and believes he's going to have success with pressuring the New Zealand heavyweight.
The pair will fight for the WBO world heavyweight title in Auckland next month.
Ruiz told Fight News that he's as studied the past fights of the 24-year-old Parker, and he's noticed that the New Zealand can't fight well going backwards.
Ruiz wasn't impressed with how the 6'4" Parker fought in his narrow 12 round unanimous decision win over Carlos Takam in May in their fight in the WBO heavyweight eliminator bout.
"In his fight against Carlos Takam he didn't really look that good, he's not good fighting backward," Ruiz said.
"That's going to be my advantage, pursuing him and throwing my combinations."
Ruiz also told Fight News that old he enjoys coming up against taller opponents and Parker will have a significant height advantage on December 10th in Auckland.
"I have been fighting tall fighters all my life so this fight is not going to be any different. I like fighting taller fighters because tall fighters don't like to fight short fighters … they don't like them always being there.
"I like to move and always like being there, it gives problems to a lot of top fighters. I find short guys more difficult, they turn in a little ball and it's harder to get them. Taller fighters, with your speed and combinations, it's a direct target."
