He was a member of South Africa’s Under-19-team which made the final of the 2002 World Cup.
Kleinveldt was fast-tracked into first-class cricket by Western Province in 2002/2003, but did not prove to be an instant success.
He spent some time with the province’s B-side and forces his way back into the first X1 thanks to a superb six for 22 against Border.
Several impressive seasons with the Cape Cobras forced him into the national reckoning, and he was included in the South Africa A side touring India in 2007.
Kleinveldt made his Twenty20 international debut in November 2008 but that proved to be a forgettable experience, as he conceded 20 runs in one over.
He continued to impress at first-class level, and took three five-wicket hauls in seven matches for the Cape Cobras as he finished with 32 wickets in the 2011/2012-season.
Kleinveldt made his test debut against Australia in Brisbane in 2012, but had considerable trouble with 12 no-balls and a wide in the first test and conceded 97 runs in 21 overs.
The seam bowler operated with more control and considerable more success in the second test at Adelaide. He removed the first three Australians and finished with three for 65 in 19 overs.
In his One Day International debut for South Africa against New Zealand at Paarl, Kleinveldt bowled with reasonable control to capture two for 37 in nine overs.
The all-rounder was one of a few standout-performers for the Proteas in the ICC Champions Trophy semi-final against England at the Oval in June 2013, He scored 43 while featuring in a 95-run partnership for the ninth wicket with David Miller, and captured one for 10 in four overs.
Kleinveldt showed his mettle for the Cape Cobras in the Sunfoil Series with a match-haul of nine for 89 against The Unlimited Titans in the 2013/2014-season. His seven for 34 in a new-ball spell characterized by venom, swing and seam, was one of the finest of his career.
His 27 wickets in the campaign at an average of 22.07 was a key factor in the Cobras retaining their Sunfoil Series title.
Capable of clearing the ground with ease, Kleinveldt can be a devastating hitter down the order.
A knee injury kept him side-lined for longer than five months in 2014 and he was ruled out of contention for the South African tour to Sri Lanka and Zimbabwe.
He nursed a hamstring-injury during part of the Momentum One Day Cup competition and Ram Slam T20 Challenge campaign of 2014/2015.
