The Kovsie Annerie Dercksen is one of South Africa’s most promising youngsters and climbing the cricketing ladder.
She enjoyed every second of playing with some of her heroes and believes the exposure to international cricket will help her become a better player.

Star from Beaufort West
This second-year Education student from the University of the Free State (UFS), who dreams of playing for the Momentum Proteas, represented the South African Emerging Women’s team three times in 2021.
The star from Beaufort West toured with the side to Bangladesh and also played against Zimbabwe and Thailand in One Day and T20 matches.
According to Dercksen, it is an incredible honour and privilege to be a part of a side.
She soaked up the experience and says everyone was willing to share their knowledge.
“I would have to say, sharing the field with some of my heroes and getting to work with some of the best coaches in the country are some of the highlights.”
She says each tour brought its own challenges and this helped her grow in the way she views and approaches the game.
“In Bangladesh we played against a well-established team in foreign conditions while facing a lot of spinners in spin friendly conditions. Personally, it was quite a challenge and I had to come back and work on some options, especially against spin.”

Coming through the ranks
The all-rounder has come through the ranks. She represented South-Western Districts at school level, played for the South African U19 side and is currently representing the Free State.
But Dercksen didn’t always dream cricket, especially not when playing ‘backyard’ cricket with her brother on the farm.
She didn’t even play for a team at school. “Until a boy from our primary school’s team got sick before a game. A teacher came to class and asked, ‘who can play cricket’, and I put up my hand.”

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
