Botha helped by returning to basics after doosra ban

Going back to basics and ditching his doosra after an international ban has revitalised Johan Botha's career, the South African off-spinner said after his seven-wicket haul in the final Test in Barbados.

Botha returned match figures of seven for 102 against West Indies in only his third Test to help South Africa clinch the series 2-0 on Tuesday.

The 28-year-old was called for a suspect action on his Test debut against Australia in 2006. He was banned until he remodelled his action and subsequently cleared by the International Cricket Council (ICC).

Botha was then forced to undertake testing once again after his action was questioned in a One-Day International against Australia and he was banned from bowling the doosra, the delivery which turns away from the right-hander.

"It (being barred from bowling the doosra) has helped a bit, there are no more worries about my action and I can just concentrate on one or two things and keep it as simple as possible and that's really helped," he said.

Botha said he focussed on adjusting his pace after losing the doosra.

"Change of pace and a little bit change of length (but) the main thing is you still have to be consistent and I think that's why I did quite well in this game," he said.

"I have not done it in four day cricket in South Africa as well as I wanted but this game I was really happy with my performances."

Despite his man-of-the-match performance, Botha does not see himself as a threat to Paul Harris as the first choice spinner in the South Africa side.

"Harry has done a great job over the last three years, you can't just judge him over one or two games. It is easier when the ball is turning into you and we come up against teams later in the year Pakistan and India which have got a lot of right handers and that suits Harry," Botha said.
