#1 Sheamus vs. Yoshi Tatsu

Sheamus is jacked young man with a reputation for being tough. He has world title victories to his name, and has been a WWE mainstay for nearly a decade now. You can compare that to Yoshi Tatsu, a guy who didn’t look all that impressive by WWE standards, and never climbed any higher than the mid-card for the company.
The two got into a confrontation years back. Some rumours suggest Sheamus owed him money. Others limit the scope of the disagreement to Tatsu taking out his and others’ frustrations about Sheamus neglecting, multiple times, to clean a communal blender backstage.

Regardless, neither man backed down for a fight, and the bigger Celtic Warrior probably didn’t realize Tatsu’s shoot boxing and fighting background. Onlookers all seem to agree that there was no question Tatsu got the better of Sheamus.
Of course, Tatsu’s place as a wrestler didn’t really improve and he wound up released by the company. While Sheamus isn’t a main eventer anymore, he remains a regularly featured star on WWE’s main roster.
