Cardiff - Wales "ran themselves into the ground" to hold off Ireland and stay in Six Nations title contention, coach Warren Gatland said after a 23-16 victory at the Millennium Stadium on Saturday.
The visitors, chasing the game after conceding an early 12 points, threw everything at Wales but their grand slam hopes were extinguished by a dogged red line of defence.
Joe Schmidt's Ireland enjoyed two-thirds of possession, made more than twice the amount of metres than their opponents and comfortably won more rucks and mauls.
