Rising Colombian star Anthony Zambrano produced a major surprise at the World Athletics Championships Doha 2019 last month when he raced to 400m silver. The 21-year-old clocked a notable 44.15 to clip a hefty 0.14 from the South American record set by Brazil's Sanderlei Claro Parrela at the 1999 World Championships in Seville when Zambrano was barely a year old.
