The Sharks returned from their Australasian tour at the top of the Super Rugby log while the Bulls and Stormers continued their good home form this weekend.

The Durbanites beat the Blues for the 10th consecutive time, by 29-23, in Albany on Friday morning. They won three from four on tour Down Under, which is equal to their best tour ever in 2009, and bagged 13 log points in Australasia, firming their grip of the top spot on the standings after four tough games abroad.

It was the first SA clean sweep of New Zealand since 2010.

Later on Friday, the Bulls were at their brutal best as they probably recorded their best win of the season when they dismantled the 2013 runners up, the Brumbies, by 44-23 at Loftus Versfeld. The score probably flattered the visitors as the side from Pretoria remained unbeaten at home this season.

On Saturday morning in Perth, the Lions fought very hard to win their final tour match, but ultimately came up short as they were beaten by 29-19 by the Force.

Round 15 came to an exciting end in Cape Town on Saturday evening when the Stormers beat the Toyota Cheetahs by 33-0 in a rather one-sided match.

It was only the third time ever a team managed a clean sheet in a South African derby – the first time was in 1999 when the  Sharks beat the Bulls by 29-0, while the team from Pretoria beat the Southern Kings by 34-0 last year.

In total, it was the fifth time ever a SA franchise failed to score a point in a Super Rugby match. The Bulls lost 27-0 to the Crusaders in Timaru in 2011 and the DHL Stormers lost 22-0 to the Crusaders in Cape Town in 2008.

Sharks captain Bismarck du Plessis said his side's game-plan went according during Friday's 29-23 win over the Blues in Albany.

"Three wins against three tough teams, we're happy with that," said Du Plessis.

"We wanted to put them under pressure at scrum time and line-outs and we did that, particuarly in the first half."
