Off the top of my head, Dibiase made him pass out to the Million $ Dream to win the tag belts.
It's not a pin but, IMO, a submission is even better.
Not sure if it was televised on Prime Time or not but Yokozuna pinned him shortly before Quake left the company.
Not sure if this is what you're thinking of, but when Earthquake walked out in 1994, they aired clips from a house show of Yokozuna sitting on Earthquake after the Banzai Drop, and talked about it to give the impression that Yokozuna had run Earthquake out of the WWF.
I was referring to a match in late 1992-early 1993 prior to Quake's 1st departure from the company. Fuji still had the buzzcut. But I know what you're talking about since Quake was scheduled to have a KOTR Qualifying Match against Owen Hart that week. I figured Owen was fucked since Quake just beat Yoko in a Sumo Match on the previous Raw. Luckily since Quake was taken out, Doink was the replacement and Owen had little problem disposing him.
