The Lions finished their three-match tour of Australia unbeaten after victory over the Brumbies in Canberra on Friday by 13-6 after trailling 3-0 at half-time.
The Lions, who had previously beaten the Force and Rebels while Down Under, scored the only try of the match through a superb solo effort by livewire flank Kwagga Smith. Flyhalf Elton Jantjies added the conversion as well as a penalty, while fullback Andries Coetzee added a late penalty as well.
The Brumbies replied with two penalties by pivot Wharenui Hawera.
The Lions picked up four points for the victory and drew level with the Crusaders at the top on the Overall log, but remain second on points difference having also played one extra match.
The Brumbies picked up a single point for losing by seven or fewer points, and stretched their lead atop the Australian Conference to five points ahead of the Waratahs.
In next weekend’s Round 13 action, the Lions welcome the Bulls to Emirates Airline Park (Saturday, May 20 at 17:15).
