He has an unusual ODI shirt number which reads '5+0'. This is as a mark of respect to the late Hansie Cronje who wore the number 5 during his career: with Cronje's death his shirt number was retired and South African players do not sport the number 5 without a '+' or zero after it.
Prince moved from Eastern Province to Western Province in the mid 90s under the instruction of Duncan Fletcher who saw potential in him. Ashwell played 2 seasons for English cricket team Morecambe Cricket Club in his earlier career, After being named Western Province's player of the year in 2001, Prince came to the attention of the selectors. He made his Test debut in February 2002, against Australia at the Wanderers. His inclusion in the side was partly due to the quota system in South Africa. He however justified his spot in the side by making 49 and top scoring. In the third Test at Durban he narrowly missed out on a half century again but his 48 was influential in his sides victory.
