Robin Peterson has been reprimanded for smashing the stumps in celebration after he hit the winning runs in South Africa's gripping one-wicket win over Sri Lanka on Wednesday in Guyana.

"It was decided to give him an official reprimand, no fine will be imposed," match referee Jeff Crowe told reporters after Peterson attended a hearing on Thursday.

Peterson ended the match when he edged a four to the third-man boundary off fast bowler Lasith Malinga, who took four wickets in four balls to take Sri Lanka to the brink of what would have been a famous victory.

When Peterson reached the other end of the pitch, he smashed the stumps to celebrate the victory.

"I actually meant to swing my bat above the stumps but my spikes got caught up in the pitch and I lost balance," Peterson told reporters after the match.

"It didn't look pretty but I'll take the two points, whatever it looked like. I'm just so happy to be able to contribute towards the win."

The International Cricket Council took a dim view and summoned Peterson to a disciplinary hearing.
