Mharakurwa found the going tough in the round of 16 losing to world number 9 Austrian Martin Lergner 6-2, 6-1 in straight sets.
Mharakurwaâ€™s hopes of continuing in the competition were dashed when he and his South African partner Marshal Marsh lost 4-6, 6-4 and 8-10 against Canadian Keegan de Cure and Ohbri Cheein the initial stage of the doubles competition.
In a telephone interview, the three time Zimbabwe sports person of the year with a disability described his performance as â€œvastly improvedâ€ indicating he is now setting his sights at the Harare Open expected to be staged this May.
Mharakurwa had stormed into the round of 16 after winning his first singles match at the South Africa Open Wheelchair tennis after posting a 6-1, 4-6, 6-1 victory over Spanish Daniel Caversachi.
The results shattered Mharakurwaâ€™s hopes of winning the singles event, and took him a step backwards after reaching and bowing out of the semi finals in 2008 and 2009 in the same competition.
