Yokozuna Terunofuji overcame a tough challenge to remain among the unbeaten leaders with a 4-0 record on Wednesday at the Kyushu Grand Sumo Tournament.

No. 2 maegashira Onosho and Terunofuji provided most of the thrills on Day 4's final bout at Fukuoka Kokusai Center. Onosho, who entered the contest with a 4-2 record against the yokozuna, kept Terunofuji off his belt from the get-go and fought him to a standstill at mid-ring.

As Terunofuji's frustration appeared to mount, he made more and more aggressive lunges toward his opponent. But Onosho dodged those efforts and began sliding the yokozuna back toward the straw.
