O’Mahony: It’s got to be our best to beat Scarlets

The Munster captain led his side into next weekend’s final with a 23-3 victory for the league table toppers over fourth-place finishers Ospreys at Thomond Park on Saturday, the Irish province outgunning the Welsh region by three tries to none, breaking out of an 8-3 arm-wrestle after a first-half try from Francis Saili with second-period scores from Simon Zebo and Andrew Conway.
Yet O’Mahony recognises that beating Scarlets will take something else again from Rassie Erasmus’s side, given the blistering form Wayne Pivac’s side has shown this year, winning 11 of their last dozen Pro12 games, including a 30-21 win at Thomond Park in February having trailed 21-6 at the interval.
