Wiaan Mulder's incredible innings of 367 not out has put South Africa in a commanding position against Zimbabwe in the second Test at the Queens Sports Club in Bulawayo. Mulder's monumental score, the highest ever by a South African in Test cricket, helped the Proteas reach a formidable total of 626 for five before he declared at lunch on Day 2.

Resuming the day on 264, Mulder continued his dominance over the Zimbabwean bowlers, quickly dispatching any loose deliveries. He reached his triple century off 297 balls, the second-fastest in Test history behind Virender Sehwag's 278-ball effort. Mulder then surpassed Hashim Amla's previous South African record of 311 with successive boundaries. His innings included 49 fours and four sixes, showcasing his aggressive intent.

Mulder's score is the fifth-highest individual score in Test cricket, behind Brian Lara's 400*, Matthew Hayden's 380, Lara's 375, and Mahela Jayawardene's 374. He is also the first player to score a triple century in their first innings as captain at Test level. Despite being only 33 runs short of breaking Brian Lara's world record of 400, Mulder declared the innings closed. Mulder said that his respect for Brian Lara and advice from coach Shukri Conrad led to his decision to not chase the record.

Zimbabwe's response to South Africa's mammoth total was poor, as they were bowled out for just 170. Sean Williams was the only batsman to offer any resistance, scoring 83 not out. Debutant Prenelan Subrayen was the pick of the South African bowlers, taking four wickets for 42 runs. Mulder also chipped in with two wickets.

South Africa enforced the follow-on, and Zimbabwe ended Day 2 on 51 for one in their second innings, still trailing by 405 runs. Takudzwanashe Kaitano was 30 not out and Nick Welch was 6 not out at the close of play.

Earlier, on Day 1, Mulder's unbeaten 264 had already put South Africa in a strong position. He took over the captaincy from the injured Keshav Maharaj and led from the front. South Africa had lost their openers cheaply after being put into bat, but Mulder combined with David Bedingham for a 184-run partnership and with Lhuan-dre Pretorius for a 217-run partnership to seize control.

South Africa already lead the two-match series 1-0 after a 328-run victory in the first Test. With Zimbabwe trailing by a massive margin, South Africa are in a strong position to win the second Test and the series.
