On May 12, 2018, ONE Championship crowned a new but old champion at the Jakarta Convention Center in Jakarta, Indonesia. Like in the previous events of the promotion in 2018, ONE Super Series bouts and mixed martial arts matches were intertwined at “ONE: Grit and Glory.”
The second bout of the evening was between Indonesian national wrestling champion Elipitua Siregar and countryman Dodi Mardian. Siregar figured in a brilliant professional debut, dominating Mardian in the first round to score an exciting submission victory.
