Rio Olympic bronze medalist Takanori Nagase secured his fourth straight national invitational weight class championship on Sunday and a place in this summer's world championships in the men's 81-kg division.

Nagase defeated Hayato Watanabe in the final on points after extra period at Fukuoka Kokusai Center to continue his domestic dominance, and will now seek to defend his title in Budapest, where the worlds will be held starting Aug. 28.

It was a completely different story for Rio 90-kg gold medalist Mashu Baker, however. He pulled out in the first round with a right-shoulder injury in his first post-Olympic tournament.
