'That's not usually how you land an armbar at that angle, but it works. It was a lot like judo transitions, where you scramble the second you hit the ground. 'I made that up on the fly, to be honest. But it was kind of funny: We were going toward the ground, and I kind of reverted back to judo mode and was thinking, 'Don't touch your back. It's a point.' 'That's where the acrobatic thing came from, was thinking about not touching your back in judo.' It was hard to work out who was more stunned, Zingano or the sell-out 17,000-crowd at the Staples Center. 'She's really good ... but that wouldn't happen again,' the beaten challenger said.

Rousey tvingade utmanaren att ta sig ur. "Vi väntade att hon skulle komma ut och göra något flygande på mig direkt," Rousey sade. Det brukar inte vara så man landar en armbåge i den vinkeln, men det fungerar. Det var ungefär som judoövergångar, där man förvränger så fort man träffar marken. Jag hittade på det i all hast, ärligt talat. Men det var lite lustigt: Vi gick mot marken, och jag liksom gick tillbaka till judoläge och tänkte: "Rör inte ryggen. Det är en poäng. Det var där akrobaten kom ifrån, tänkte på att inte röra ryggen i judo. Det var svårt att räkna ut vem som var mest chockad, Zingano eller den utsålda 17 000-befolkningen på Staples Center. "Hon är riktigt bra ... men det skulle inte hända igen," sade den slagna utmanaren. "Det var ett knä och sedan ett kast och sedan en scramble, och sedan var hon lindad runt min arm. Jag åkte fast. Jag var redo att göra en miljon olika saker. Jag planerade att hamna i ett knytnävsslagsmål i kväll.' Zingano ser ut i smärta när Rousey flyttar sig i position för att utföra armbarsfinishen.

Holm avslutade under tiden en 11-årig proffsboxningskarriär för att koncentrera sig på MMA för två år sedan men såg långt ifrån det kompletta paketet mot Pennington.
