Brumbies coach Stephen Larkham admitted that becoming the first Super Rugby team to lose to the Blues in 2015 is a disappointing result and the Blues first half lead won the match for them.
The Brumbies fought their way back from being 13‑0 down at half time to leading 13‑14 with seven minutes remaining.
However the Brumbies conceded a penalty for offside in the 76th minute and replacement Ihaia West slotted the penalty to take the lead back.
Larkham said it was a disappointing result.
In tonights matches the Crusaders meet the Highlanders at 7.35pm, the Waratahs face the Stormers at 9.40pm while the Force take on the Cheetahs at 11.40pm.
