Flyhalf Otere Black scored a try among 19 points as the Auckland-based Blues beat the Dunedin-based Highlanders 39-17 Sunday in Super Rugby Aotearoa. The Blues took a bonus point from the five tries to two win to stay unbeaten after three matches in the New Zealand domestic tournament while the Highlanders are now 2-1 after three games. Poor discipline cost the Highlanders who were repeatedly penalized at the offside line and at scrums.
