Steph Curry is a miracle worker ... 'cause he mentored a boxing star who NEVER touched a basketball in his life -- into hitting a free throw shot on an NBA court.
Seriously, it's one of the ugliest shots ever -- but props to both Steph and Amir Khan ... because despite the ridiculously awkward shooting motion -- Khan hit the shot!
Still, Amir ... don't quit your day job, bro.
