Ozeki Terunofuji appears poised to earn promotion to sumo's highest rank of yokozuna after reeling off his 13th straight win on Friday, leaving him tied with yokozuna Hakuho for the lead at the Nagoya Grand Sumo Tournament with two days to go.

Terunofuji entered the 15-day meet at Dolphins Arena with the knowledge that a third straight championship here or a comparable record would earn him promotion.
