Steven Finn bowled himself into contention for a return to England's line-up after taking four wickets on Sunday on the opening day of the last warm-up game before they begin the Test series against South Africa on Boxing Day.
Finn was only drafted into the squad last week, but underlined his credentials against South Africa A by taking four wickets for 34 runs at the City Oval.
England bowled out their opponents for 136 runs and scored 64 without reply before bad light curtailed the game and stumps were drawn.
Finn, who was forced out of the test series against Pakistan in October after injuring his left foot, was flown over to South Africa after impressing for England Lions in two comeback appearances against Pakistan A in Dubai.
