There actually appears to be some controversy as to how many eliminations Strowman has.
While wwe.com and wikipedia (which appears to just be copying wwe.com thinking that's official) lists 4 each, multiple other websites like bleacher report and cbssports (amongst the ones I've checked) are saying he has 5.
The discrepancy appears to come with the elimination of Jeff Hardy. WWE is stating Hardy was elimianted by Mcintyre, these other websites are saying he was eliminated by Braun.
While WWE would SEEM to be the official authority on this, their website can't be taken as 100% correct. This is a screenshot of the official wwe.com results. They have "Alexa Bliss" listed as the eliminator of Rey Mysterio lol. So clearly wwe.com has some issues
I haven't gone back on the network and watched the rumble. And I won't be able to this afternoon.
If anyone has, or does, please let me know who eliminated Jeff Hardy.
For now, we can go on the assumption of a tie.
