Tamawashi remained alone atop the leaderboard regardless of taking his second lack of the Autumn Grand Sumo Event by the hands of fellow rank-and-filer Wakamotoharu on Thursday.
The Mongolian-born No. 3 maegashira maintained a one-win buffer at 10-2 after his nearest rivals coming into Day 12, No. 8 Hokutofuji and No. 10 Nishikifuji, have been crushed by ozeki Takakeisho and No. 1 Tobizaru, respectively.
