Heinrich Klaasen says he made a small technical adjustment to his batting before scoring a 61-ball 119*.

Klaasen’s second ODI century powered the Proteas to a series-levelling four-wicket win against the West Indies in Potchefstroom on Sunday.

However, he revealed afterwards that he hadn’t been middling it in the nets in the build-up to the game.

“We just fixed a little technical thing at the nets after 50 balls of edging and surviving balls.

“I just tried to stay nice and still and calm. I think after that, I hit a couple of better balls and everything seemed to hit the middle of the bat a bit better.

“I took that confidence into today’s game.”

HIGHLIGHTS: Proteas vs West Indies (3rd ODI)

Needing 261 to win, the Proteas were in trouble at 87-4 before Klaasen shared partnerships of 55 off 38 balls with David Miller and 103 off 62 with Marco Jansen.

Klaasen reached his hundred in 54 balls – the fourth-fastest in ODI cricket for the Proteas behind two from AB de Villiers (who holds the world record for the fastest with his 31-ball hundred against the West Indies at the Wanderers in 2015) and one from Mark Boucher.

“It was one of those days where the first couple of shots went into the gap,” Klaasen said.

“To be quite honest, the rest was simple for me. We’re trying to play the conditions and not the situation, and the conditions were fantastic to bat on.

“I felt like I had a couple of loose deliveries that I capitalised on, and I felt that set the tempo for my innings.

“I didn’t have to take too many risks, even though I took one or two, but the good ball I could have respected.

“There was no pressure, even when I got in, to chase any sort of big run-rate when the conditions are that good.

“You just have to bat through and play each ball on its own merits.”
