SA sprinter Akani Simbine secured a win in the men's 100m on day two of the SA Track and Field Championships in Tshwane on Friday.
Simbine stopped the clock in 9.99 seconds in the 100m final to claim victory ahead of Gift Leotlela (10.16) and Thembo Monoreng (10.33).
In the opening day of the SA Championships on Thursday, Simbine nearly shattered his national record as he broke won in 9.82 seconds - although he had the benefit of a +2.8m/s tailwind.
"I came here to be SA number one, so I'm happy with my run," Simbine said in a Athletics South Africa (ASA) press release.
"I'm glad to run another sub-10 and the key is to stay healthy. It's another big year and I'm sticking to the main goal, which is the Tokyo Olympics."
Meanwhile, the women's 100m final on Friday was won by Reabetse Moloi, who crossed the finish line in a time of 11.55 seconds.
"I'm really happy. I had a lot of challenges getting here. It was not an easy medal. I wish the time was a little faster but I'll take the win," said Moloi.
Producing the major upset of the day, Tiaan Kleynhans won the men's 110m hurdles final in 13.62, with SA record holder Antonio Alkana relegated to fourth place in 14.02 after hitting a hurdle and losing his balance.
200m record holder Clarence Munyai scrapped into the final as he finished third in his semi-final in 21.03 seconds. It was a close call for Munyai, who would not have qualified for the 200m final if he finished 0.02 seconds slower.
Marga Cumming won gold in the women's hammer throw with a best attempt of 64.30m. Cumming's winning heave landed just one centimetre short of the 64.31m* national record she set in Potchefstroom in February.
Her brother, Alan Cumming made it a family one-two by taking the men's hammer throw title with a 72.78m effort.
Mire Reinstorf dominated the women's pole vault final, clearing the bar at 4.00m, while Leyton Davids' best leap of 16.46m was good enough for gold in the men's triple jump. Zinzi Xulu won the women's triple jump final, landing at 13.34m.
Nkosinathi Sibiya (3:42.92) and Danielle Verster (4:20.54) won gold in the men and women's 1 500m finals.
In the men's 200m semi-finals, 400m world record holder and Olympic champion Wayde van Niekerk won his semi-final in 20.38 and he will line up as the firm favourite in the half-lap final, to be held on Saturday.
"All credit to great performances of the day. The sweat and tears of the athletes tell us of the determination and hard work that have been put into preparation of this championship," said ASA president. Aleck Skhosana.
