Umaru has played tennis professionally since 2005, and has represented the Nigerian national squad at Junior ITF, Men's ITF and Davis Cup tournaments. He is currently ATP ranked No. 1,527 and has a national ranking of No. 13. It was only natural for him to put those skills to use and teach others - he decided to become a professional coach and had stints in the US and Nigeria, before settling in Dubai. Umaru is a regular hitting partner for some of the biggest names during the Dubai Duty Free Championships.
