If you were paying attention during the Rio Olympics in 2016, then Akani Simbine is a name that you know. He's the 22 year old South African who held his own against runners like Usain Bolt and Justin Gatlin in the 100-meters, coming fifth place 0.01 seconds behind Johan Blake.

On Monday night, Simbine faced Blake again, and this time, he took gold. With a time of 10.03 seconds, Simbine crossed the finish line with one arm held up in victory. His fellow South African Henricho Bruintjies came in second at 10.17 seconds, just beating out Blake, who came third at 10.19 seconds.

"I came here wanting to be on the podium. I believed in myself, that I could get the gold medal," Simbine said.

Blake, who is tied with Tyson Gay as the second-fasted man in the world behind Usain Bolt, was heavily favored to win the race. In fact, Bolt joked earlier this week that Blake could not return to Jamaica unless he had the gold medal with him.
