The Stormers beat the Boland Kavaliers 57-0 at Cape Town Stadium.
The Cape franchise scored nine tries, with Siya Kolisi getting a hat-trick in the space of 13 minutes and Gio Aplon a double. New fullback Jaco Taute also scored his first try in Stormers colours.
The Stormers led 17-0 at half-time, but ran rampant after the break as the rain stopped and the sun came out.
The only negative for the SA conference champions was the ankle injury sustained by Bok lock Eben Etzebeth, who limped off early in the first half.
‘We’re a bit nervous about Eben’s ankle strain,’ said Stormers coach Allister Coetzee. ‘He landed awkwardly at a lineout and will have a scan tonight.’
