Former South Africa all-rounder Johan Botha has announced his immediate retirement from all forms of cricket.
Botha's Australian Twenty20 league team, the Hobart Hurricanes, announced the news late Wednesday.
It said Botha cited "wear and tear on his body and sheer physical fatigue."
The 36-year-old Botha, who received his Australian citizenship in 2016, failed to take a wicket during Wednesday's nine-wicket loss to the Sydney Sixers.
He had played all 10 matches for the first-place Hurricanes this season.
"To the Hobart Hurricanes, thank you for making my last season one I will remember forever...I will be your number one supporter," he wrote in his farewell letter.

Botha played for South Africa in five Test matches, 78 one-day internationals and 40 T20 Internationals from 2005 to 2012.
Botha captained the Proteas in 10 ODIs and took the team to the No. 1 ranking after they defeated Australia 4-1 in Australia in 2009.
