The Stormers had the scrum advantage, bulldozing forward given the opportunity but the Brumbies had the better lineout. Ben Mowen was the star - his steals have become a habit this season. Kiwi Jack Whetton also produced a fine display in his Brumbies debut.
The Stormers never surrendered. That was demonstrated by their 70m counter-attack, again featuring Aplon, from their own line in the 71st minute when Nic White missed a penalty. Vermeulen was relentless, using his mass to surge at will.
The visitors were rewarded with a final try to Juan de Jongh in the 75th minute but the missed conversion from just to the left of the posts by Peter Grant stymied the last thrust.
Brumbies 25 (R. Coleman 2, penalty tries, N. White 2 con, 2 pen) Stormers 15 (D.Vermeulen, J. de Jongh tries, P.Grant con, pen). Halftime: 13-10.
