Great Britain’s Sam Ward made a dream return to Olympic action as his side won their men’s hockey Pool B opener against South Africa.
The 30-year-old struck from a penalty corner after just two minutes.
Matt Guise-Brown levelled from another penalty corner a minute later but second-half goals from Liam Ansell and Jack Waller gave GB a winning start.
With tough games against Belgium, Germany and the Netherlands to come, Danny Kerry’s side needed a good display against one of the two Pool B teams ranked lower than them to boost their quarter-final hopes.
And while Great Britain were tested by their opponents early on, South Africa’s ill-discipline cost them as the game went on.
Kerry’s side next face Canada on Monday.
