Dana White furious with referee Mario Yamasaki for letting debutant’s annihilation go on way too long

Not for the first time, Dana White is upset with Mario Yamasaki.

Valentina Shevchenko looked phenomenal in her UFC flyweight debut in Belem, but it was Mario Yamasaki's officiating of the bout that dominated the post-fight discussion. Number one women's bantamweight contender Shevchenko showed the world why she's seen as the uncrowned queen of 125 lbs on Sunday morning. 'Bullet' completely outclassed promotional newcomer Priscila Cachoeira, ending the Brazilian's unbeaten run in the lion's den. Shevchenko beat her up on the feet and beat her up on the ground before forcing the tap with a rear-naked choke at 4:25 of the second round. https://twitter.com/UFCONFOX/status/960023602291617792 Although it lasted deep into the second, the fight was over as a contest by the end of the first. Cachoeira was clearly out of her depth against the combat sports veteran. While striking stats can often be deceiving in MMA, they really told the story of this fight. According to FightMetric, Shevchenko outstruck her opponent by 217-1. That's right, unofficially, Cachoeira landed just one strike in the entire fight. At one point, Shevchenko had her opponent in a crucifix position on the ground. She relentlessly hammered ground-and-pound on the helpless fighter. Yamasaki kept having a look at the situation but refused to step in. No wonder why Dana White was so pissed off at him after the fight. White has been one of the biggest critics of the ref for years. He took to Instagram to voice his disgust over Yamasaki's performance. https://twitter.com/TheJivemaster/status/960032593839353856 He wasn't alone in his outrage. Plenty of fighters, fans and personalities took to social media to give out about Yamasaki. While some suggested her corner should have thrown in the towel, nobody was defending Yamasaki after the fight. https://twitter.com/MikeBohnMMA/status/960024846443757568 https://twitter.com/RdosAnjosMMA/status/960025362133483520 https://twitter.com/GilbertDurinho/status/960023098820046849 https://twitter.com/kennyflorian/status/960024298340605952 https://twitter.com/MMAjunkieSteven/status/960023439347105792 https://twitter.com/MMAjunkieSteven/status/960023899005054976 https://twitter.com/jeremybotter/status/960023084987305984 https://twitter.com/VinnyMMA/status/960023064598556672 https://twitter.com/jeffwagenheim/status/960023060328996865 https://twitter.com/AdamHillLVRJ/status/960023007639908352 https://twitter.com/KelvinGastelum/status/960023276507381761 https://twitter.com/MMAHistoryToday/status/960023159360532480 https://twitter.com/MMAPod/status/960023322716246021
