Leinster Rugby back Jordan Larmour moved his eye-catching Heineken Champions Cup form to a new level on Saturday with a sensational second-half hat-trick of tries as Ireland dismantled Italy 54-7 in Chicago. The last of his treble was a stunning score from inside his own half, weaving past numerous weary Italian defenders before darting down the left wing and diving over the try line. The 21-year-old, who was Ireland’s full-back on Saturday, has already impressed this season in European competition, scoring his first Heineken Champions Cup try in Leinster’s 52-3 home win over Wasps in Round 1. Munster Rugby lock Tadhg Beirne also got in on the act in the USA, scoring his first two tries for his country either side of half-time. https://twitter.com/ChampionsCup/status/1059085693522272256 Ulster Rugby centre Will Addison and Leinster fly-half Ross Byrne both made their international debuts for Ireland off the bench, with the latter slotting over two late conversions. England head coach Eddie Jones handed a Test start to Newcastle Falcons No. 8 Mark Wilson and Test debuts to Exeter Chiefs prop Ben Moon and Bath Rugby No. 8 Zach Mercer off the bench as they ground out a 12-11 win over South Africa at Twickenham on Saturday. Saracens fly-half Owen Farrell kicked nine points in the win, while Wasps full-back Elliot Daly landed a long-range penalty in the second half. https://twitter.com/Saracens/status/1059038181532803078 Scarlets full-back Leigh Halfpenny kicked 11 points as Wales defeated Scotland 21-10 at the Principality Stadium in Cardiff on Saturday. Scarlets centre Jonathan Davies also got on the Wales scoresheet with a try, but it was Cardiff Blues fly-half Gareth Anscombe who was the hosts’ inspiration, continuing his excellent Heineken Champions Cup form. The 27-year-old has already scored 22 points in the competition this season, with 20 of them coming in the Welsh region’s 30-21 win over Lyon in Round 1.
