Undefeated and Unified Heavyweight World Champion Anthony Joshua went the distance for the first time in his career, outpointing previously undefeated champion Joseph Parker in a heavyweight unification bout Saturday on SHOWTIME in Cardiff, Wales.

IBF, IBO and WBA Heavyweight World Champion Joshua (21-0, 20 KOs) added Parker’s WBO title to his mantle with a 118-110, 118-110, and 119-109 unanimous decision before a boxing indoor attendance record of more than 78,000 fans at Principality Stadium.

While Joshua was the aggressor throughout, Parker established his jab in the early rounds in an attempt to negate Joshua’s six-inch reach advantage.  And while Parker had his moments, Joshua was more active and landed the more meaningful punches and appeared to stagger the New Zealander on a handful of occasions.

In the championship rounds, it seemed the 28-year-old Joshua was going for the KO against Parker, who displayed a solid chin in becoming the only fighter to push Joshua the distance.

“I am not going to judge my performance,” Joshua said.  “That’s for my coach to do.  My strategy was to get behind the jab and we did that.  The good jab will take you around the world.

“Through rounds 10, 11, 12, I was focused.  I went the 12 rounds and I fought him hard, but it was light work.  This is boxing.  This is what we do.  Joseph Parker is a world champion.  I knew he was going to be determined.  Sometimes this is how it goes.  It becomes a tactical boxing fight.  This was going to be about finesse, and I controlled behind the jab and used finesse.

“We cannot forget – I am now the unified heavyweight champion of the world.”

Joshua didn’t seem disappointed he was unable to score a KO yet still admitted he wasn’t satisfied with the first distance fight of his career.

“Definitely, we are not satisfied.  One step at a time,” Joshua said.  “We are not our best yet but we are at the pinnacle of boxing.  I always go in the deep end, always challenge myself.  I am ready for more challenges.  We will see what’s next.”

The 26-year-old Parker (24-1, 18 KOs) didn’t dispute the decision in what was the first unification fight between undefeated heavyweight champions since 1987.
