South Africa breathed a sigh of relief when Temba Bavuma strode to the crease on day three of the four-day clash with a Cricket Australia XI.
Bavuma had reinjured an elbow in the nets that kept him out of the recent Test tour of England, and did not bat in the first innings of the tour match at Allan Border Field in Brisbane.
He was wearing a compression bandage on his left arm when he came in just before lunch in a huge boost to the Proteas chances in the first Test against Australia at the Gabba starting on December 17.
South Africa went to the break at 2-88 in their second innings after losing opener Sarel Erwee (two) to the first ball of the morning off Jordan Buckingham.
Dean Elgar (26) was bowled by a Blake Edwards delivery that kept low.
Rassie van der Dussen was unbeaten on 50 at the break after finding form while Bavuma was five not out.
Van der Dussen was strong down the ground and played a number of reverse sweeps to the boundary off spinner Matt Kuhnemann.
The Proteas lead by 209 runs after making 347 in their first innings and then bowling the hosts out for 226.
Captain Elgar (109) top-scored for South Africa in his first dig while 20-year-old Campbell Kellaway (105no) held the CA XI innings together.
