No, in fact, their first class debut happened very close to each others'. Mackay debuted when he was 31 , and Lamb when he was 18, in 1998/99 season.
This is not the only similarity, as an answer to the question, they both had their first class debut playing for the "ZCU Presidents XI".
Mackay: 2-4 October 1998, ZCU President's XI v Indians, at Sunrise Sports Club,
Lamb: 26-29 January 1999, ZCU President's XI v England A, at Kwekwe
So, no points to anybody on this one...
