Stevie McKenna wasted little time en route to a first-round knock-out victory over Scottish fighter Gary McGuire to maintain his 100% winning record in Yorkshire on Saturday night.

The Monaghan native, who is based in Los Angeles, powered past journeyman McGuire inside the first round, putting his opponent on the canvas three times before the referee called time on the bout.

"Hit-man" McKenna went straight into attack mode from the opening bell, cornering his opponent and landing regularly with a barrage of accurate punches that forced McGuire to take a knee.

Momentum and perhaps over-enthusiasm led McKenna to land a stray punch after the Scot had touched down and the referee handed the Smithborough fighter a stern warning for the late shot that landed on the top of the head.

But the one-sided fight would officially last only 1min 13secs after McGuire hit the canvas twice more in this shortest of boxing mis-matches.

McKenna's volley of punches led McGuire to take another knee in the corner in what was a carbon copy of the first knockdown, before a devastating left hook put his opponent on the seat of his pants, who then shook his head and removed his gumshield as the towel came in and the referee called time.

The win sees the Freddie Roach-trained McKenna move to 5-0 with all five wins coming by way of knock-out, as his move up the paid ranks continues after a ten-month absence from the ring.
