The Irish are one win away from a Grand Slam in the Six Nations.

By outlasting Scotland 22-7 at Murrayfield, Ireland earned a fourth straight victory of the championship to move on to 19 points — four more than defending champion France.

The French are the only team capable of stopping Andy Farrell’s relentless squad from claiming a first Six Nations title since 2018. That would require Ireland losing at fortress Lansdowne Road to visiting England and France beating Wales in a match taking place a few hours earlier next weekend.

England are hardly in great shape, either, coming off a record 53-10 loss to France in round four.

Scotland’s 12th loss in its past 13 meetings with Ireland ended the hosts’ title challenge, though the result was in the balance at halftime with the Irish only leading 8-7 thanks to Mack Hansen squeezing over for a try in the right corner in the 28th minute.

Ireland showed their experience and class in the second half, with two quick-fire tries around the hour mark killing off the hopes of the Scots, who didn’t manage to score a point after the break.

After Hansen took an up-and-under on the right flank, the ball was recycled to the left and, after a series of phases, Jamison Gibson-Park’s miss-pass found winger James Lowe, who barged through a challenge to ground in the corner in the 57th.

Five minutes later, Hansen also played a key role in Ireland’s third try by sending in replacement Jack Conan along the right touchline. The back-row forward had the huge figure of Duhan van der Merwe to hold off, but he did and got over the line.
