Of the omissions, left-armer Andy McKay's international future looks bleak at 31. He was rated the third best bowler under the HRV Cup's MVP system behind Hira and Nicol.
Instead fellow left-armer Bates (28) has been picked in both squads after taking 14 wickets at 20.85 in the HRV Cup; the most wickets, equal with Hira, in the competition. At 34, Graeme Aldridge's one chance for national selection may have been and gone with the tour to Zimbabwe.
Newly selected leg spinner Nethula gets a chance for international competition. Left-arm orthodox spinner Luke Woodcock slips out of the frame.
