Boxing divisional rankings: McKenna wins title, enters middleweight top 10

In a weekend full of middleweight action, the division crowned a new champion and saw a top contender extend his perfect record.

On Saturday in Dublin, Ireland, Aaron McKenna dominated Etinosa Oliha to claim the vacant IBF middleweight title by unanimous decision.

McKenna (21-0, 10 KOs), from nearby Monaghan, was disciplined throughout the contest, using his four-inch height advantage and strength to control Oliha on the inside. McKenna found success with uppercuts and body punches en route to a clear decision victory by scores of 118-110, 117-111 and 116-112.

With the win, McKenna debuts in the middleweight rankings at No. 9. Oliha (22-1, 10 KOs), who was fighting for the first time in nearly a year, suffered his first career loss.

In the co-main event, Callum Walsh remained unbeaten with a unanimous decision victory over Tyler Denny. Walsh overcame a first-round knockdown and an accidental clash of heads to defeat Denny by scores of 98-91, 98-91 and 96-90.

Walsh (17-0, 11 KOs) responded to the early adversity by taking control in Round 2, dropping Denny (21-5-3, 1 KO) with a left hand. Walsh continued to win rounds, but he couldn't put Denny away, as Denny continued pressing forward until the final bell.

Despite the victory, Walsh remains outside the top 10 in the middleweight rankings.

ESPN's divisional boxing rankings highlight the best in the sport in every weight class. Rankings will change based on recent results and performances. Fighters who have announced they are moving to a different weight class will be ranked in that new division, if warranted, only once they fight in that weight class. Fighters who currently own titles in two divisions can be ranked in both.

Fighters who haven't competed in the past 12 months -- and don't have a fight scheduled -- will be dropped from the rankings until they fight again. Any fighter who tests positive for a performance-enhancing substance will also be removed. That boxer will be eligible to reenter the rankings after his next bout.
