The eight players received semi-professional contracts at Western Province for the 2015/2016-season.
Apart from Kleinveldt and Hamza, Pieter Malan, Aviwe Mgijima, Lesiba Ngoepe, Travis Miller, George Linde and Mpilo Njoloza were also rewarded semi-professional contracts.
Kleinveldt scored 669 runs in the 2014/2015-season, and prospered in his maiden first-class game for the Cape Cobras by striking a composed 97 as opener against the Sunfoil Dolphins.
The 19-year old Hamza excelled, compiling a stylish 580 runs in the Sunfoil Cup Three-day competition at an average of 58.
Malan also enjoyed some memorable success for Western Province. He assembled 694 runs and pressed briefly for a more permanent position in the Cape Cobras top-order.
The contracted bowlers and all-rounders have the abilities to stake a claim for higher honours at Newlands.
Aviwe Mgijima captured 16 wickets and scored 201 runs at an average of 40.20 for Western Province last season.
Travis Miller and George Linde have made debuts for the Cape Cobras and both have taken five-wicket hauls for the senior franchise team.
Ultimately, consistent excellence and match-winning performances would be required to propel the semi-professionals firmly into the hearts and minds of the Cape Cobras selectors.
Ngoepe showed glimpses of his quality in the 2014/2015-season. Yet, he would want to convert those moments into sessions and centuries to exert more pressure on the incumbents at the Cape Cobras.
