Lendlease Breakers and Sydney Thunder allrounder Rachel Trenaman has scored her first century for her country and played a definitive captain’s knock to lead the Women’s Australian Under 19 team to a decisive 120-run victory over the South African Emerging Women’s side at Hammanskraal Mandela Oval, Pretoria, on Saturday.

In the second match of the tri-series between the Australian Under 19 team, South African Emerging Women, and the England Women’s Academy, Trenaman scored 122 from 124 balls to set an imposing total of 280 from its allotted 50 overs. 

The win followed a thrilling nine-run win against the England Women’s Academy on Thursday. 

A 119-run third-wicket partnership between the 16-year-old Trenaman and emerging Breakers’ batter Tahlia Wilson (76) was pivotal to the win.

In reply, South Africa were dismissed for 160 within 37 overs where Trenaman again starred with the ball. The Australian captain claimed 2-25.

For the second consecutive time, 15-year-old New South Wales’ fast bowler Stella Campbell (2-19) returned best figures for Australia in the second match for her country.

After it lost 2-50 within the opening 10 overs, Australia needed to consolidate and build a significant partnership that could establish a substantial first innings total which is exactly what Wilson and Trenaman produced.

The pair maintained a run-rate of more than four runs per over throughout the middle stages of the innings before their stand was eventually ended in the 35th over.

Wilson was removed for 76 from 95 deliveries, but Trenaman refused to let the departure of her Breakers’ team mate slow the right-hander down.

Trenaman shared another important 61-run partnership with Victorian middle-order batter Georgia Wareham (29), and despite the loss of 6-19 in the final four overs, Australia posted a highly competitive total which it comfortably defended.

The South African Women’s Academy lost 3-15 within the first seven overs of its response and were soon 5-43 in the eleventh over thanks to some terrific bowling by Campbell and Melbourne Renegades’ medium-pacer Tayla Vlaeminck (2-20) opening the attack for Australia.

While South African captain and opening batter, Tazmin Brits (52) did her utmost to recover the situation for her country, Australia was just too strong for their hosts.

Trenaman claimed the final two wickets to seal the win and put Australia on top of the table. It will next play England in Johannesburg on Wednesday.
