Highlanders, Crusaders, Chiefs win in Super Rugby

(AP) -- New Zealand's Crusaders overwhelmed South Africa's Stormers 57-24 to stretch their winning start to Super Rugby to eight matches on Saturday.

The New Zealand teams, who will welcome the British and Irish Lions in June, enjoyed another clean sweep.

The Dunedin-based Highlanders ran through Japan's Sunwolves 40-15, and the Hamilton-based Chiefs eked out a scratchy 16-7 win over the Western Force in Perth.
