Ireland did enough to beat world champion South Africa 19-16 in an arm wrestle at Lansdowne Road on Saturday to justify its ascent to No. 1 in the rankings.
Ireland broke a 6-6 halftime deadlock with two tries in four minutes early in the second half, the first from a lineout maul by flanker Josh van der Flier and then a more expansive counterattack score from left wing Mack Hansen.
