Russian Wakanoho has become the latest sumo wrestler to be given a ticking-off for throwing a tantrum when he smashed a shelf in the fighters' communal bathroom after losing a bout. The Japan Sumo Association (JSA) warned Wakanoho about his behavior on Monday after the 19-year-old's temper got the better of him following a loss a day earlier. “I get a bit upset when I lose,” the giant Russian told reporters. “I don't want to break things, but when I see dishes and stuff I just have to smash them.” Wakanoho's sumo “stable” master Magaki said his charge had a few rough spots to iron out. “He has difficulty keeping his emotions in check,” he acknowledged. “That's a bad thing.” Magaki has had problems of his own after being given a warning by the JSA after admitting to beating a junior wrestler with a bamboo sword. The sport has been plagued by scandal in recent months, most notably the arrest of a former gym chief on suspicion of assault following the death of a teenage wrestler.
