Malan recently hammered an unbeaten 82 and 114 in club cricket in England and will hope to extend that form to the Africa T20 Cup starting on Friday 4th September.
Faiek Davids, the Western Province coach, said he planned to use Lesiba Ngoepe, Malan, Omphile Ramela, Dane Vilas and Hamza in his top-five for the T20 Cup.
Vilas, senior player of the Cape Cobras, recently made his test debut for South Africa against Bangladesh.
Ramela hammered a century on debut for South Africa A after also concluding the Sunfoil Series competition in 2014/2015 with two centuries in his final three domestic four-day matches for the Cape Cobras.
Hamza was prolific for the South African Academy team in Sri Lanka and topped the averages in the one-day series against the Sri Lankan emerging team. He averaged 71.50 at an impressive strike-rate of 86.14.
Hamza made statistical headlines in the 2014/2015-season when he became the fourth-youngest South African player to score a double-century in a first-class game, against Namibia.
He did so at the age of 19 years and 113 years, putting him behind Johann Myburgh (17 years and 122 days), Graeme Pollock (19 years and 19 days) and Xenophon Balaskas (19 years and 86 days).
Davids said the South African left-arm swing bowler Wayne Parnell will fulfil the role of first all-rounder for the Western Province team at the Africa T20 Cup.
His ability to swing the ball both ways through the air at pace can make him a world-class bowler. He also has credentials as a hard-hitting batsman who has crafted at least two centuries in domestic limited-over matches.
If Parnell can reclaim his self-confidence and consistency, nothing prevents him from becoming a regular first-choice all-rounder for South Africa in limited-overs cricket, Davids said.
Davids added he would have loved to have his full squad available for a longer outdoor training period, but the fact that 11 of his 13 squad members are overseas, is a blessing in disguise, as they all gain cricketing exposure outdoors.
