Italy's Manassero, the youngest winner on the tour, and Spain's Jimenez, the oldest winner, were confirmed on Tuesday for the tournament at Durban Country Club from Jan. 10-13.
Manassero was 17 when he claimed the 2010 Castello Masters title. Jimenez won last month's Hong Kong Open at 48.
The new European season begins with three successive events in South Africa, starting with this week's inaugural Nelson Mandela Championship.
