Matt Zacharkow, otherwise known as 'Baby Ninja' for dressing up like baby while he runs, first compete in American Ninja Warrior 6 where he beat qualifying but in the finals went out on the Minefield just missing out on Vegas placing in 16th. He was given a wildcard spot and was seen in Vegas with his fellow Miami competitors. Fellow competitor Joseph Rosello confirmed Zacharkow's Stage One result, stating Zacharkow failed the Silk Slider. The splash created by Zacharkow would make the already slick landing platform even harder to land on.
He competed in American Ninja Warrior 7 in Pittsburgh and failed the Wind Chimes in qualifying.
