Lisa O'Rourke boxed beautifully to progress to the quarter-finals of the Women's World Championships in Istanbul on Friday.

The Roscommon native secured a unanimous decision victory over Dominican Republic boxer Maria Moronta Hernandez in the round of 16 clash of the light-middleweight division (66-70kg) at the prestigious Turkey tournament.

Happy to fight on the outside from the opening bell against her aggressive opponent, O'Rourke stayed out of harm's way using her long left jab, while backing it up with some powerful right hands in what appeared a straightforward opening stanza.

And O'Rourke picked up where she left off at the start of the second round, continuing to frustrate Hernadez, who was wasting energy, throwing a lot but rarely landing.

O’Rourke then stepped up a gear and showed her dominance midway through the three-minute round as she trapped Hernandez on the ropes, while a huge right hand landed moments after as her opponent looked to move back into the centre of the ring.

It was an excellent all-round display of boxing throughout the second as O'Rourke then finished with a flurry to catch the eye, again pinning Hernandez to the ropes.

Up on the scorecards - remarkably, one judge gave the round to Hernandez - O’Rourke just had to stay out of trouble in the final round, but maintained an aggressive approach, perhaps making a statement to the rest of the division ahead of the quarter-finals.

Light on her feet and moving around the ring with grace, the Castlerea fighter looked in complete control for the remainder of the round, although she was eventually caught by a strong Hernadez right hand.

Little to worry the Roscommon Gaelic footballer, however, as O'Rourke stayed on the front foot to ensure the commanding victory, taking the result on all five judges' scorecards.

Again, one of the five gave the final round to Hernandez, however, it mattered little as O'Rourke took a 5:0 overall result, the scores being 30:27, 30:27, 30:27, 29:28, 29:28.

It was notable that the Cuban judge gave all three rounds to the Irish fighter, no doubt, impressed by the illusive nature and boxing ability on display by the Olympic BC, Galway fighter.

O'Rourke's quarter-final fight will take place on Monday, where a victory would guarantee a bronze medal, at least.
