Brett D'Oliveira has played second XI cricket for the last two seasons
Worcestershire have awarded one-year deals to academy graduates Brett D'Oliveira and Nick Harrison.
Leg-spinner D'Oliveira, 19, will become the third generation from his family to represent the county, following father Damian and grandfather Basil.
Right-arm seamer Harrison, also 19, made his debut at Derbyshire in the CB40 earlier this month.
Director of cricket Steve Rhodes said: "The two lads have taken well to life as professional cricketers in 2011."
He added: "Becoming full professionals is in response to the improvement both players have made during their scholarship year, both on the field with their cricket and their preparation off it."
The revered D'Oliveira Snr, who played 44 Test matches for England, has a stand named after him at the Diglis End of the county's New Road home, while son Damian has been on the coaching staff since retiring in 1995.
