WWE SmackDown Results: Biggest Winners, Losers and Moments from May 21

Just days after Dean Ambrose coerced The Authority into giving him a WWE World Heavyweight Championship match against Seth Rollins at Elimination Chamber, the Lunatic Fringe rolled into Friday's SmackDown and had the best night of any Superstar on the show.

First, he verbally sparred with Director of Operations Kane and enjoyed a fun back-and-forth with Roman Reigns. Then, he avenged his defeat at the hands of Bray Wyatt from Monday night, staving off interference from Seth Rollins, Jamie Noble and Joey Mercury while doing so.

The most unstable and unpredictable star on the main roster continued to ride the wave of momentum that started when he was interjected in the title hunt prior to Payback.

With his championship opportunity right around the corner, expect to see Ambrose have more opportunities to cement himself as the biggest winner of the night, regardless of whether it comes on a live episode of Raw or canned SmackDown broadcast.

Ambrose was not the only Superstar with an upcoming title shot to have a strong night Thursday.

Which of the Superstars preparing to enter the dangerous, barbaric and hellish Elimination Chamber joined him? And who were the biggest losers of the night?

Winners: The Lucha Dragons

Sin Cara and Kalisto scored a gigantic victory in a Fatal 4-Way bout Thursday night, defeating former WWE tag team champions Tyson Kidd and Cesaro, Los Matadores and The Ascension to garner some much-needed momentum heading into their huge title opportunity on May 31.

The high-flying duo has gotten over on the main roster to a much greater extent than it did in NXT, where fans seemed bored by the team's generic babyface nature.

Now as the Dragons prepare for the biggest match of their career, they stand out as one of the two or three teams most likely to leave with the tag titles. Even if they do not, expect to see insane high-flying spots and maneuvers that leave fans talking about the Lucha Dragons in the wake of the show.

Winner: Dolph Ziggler

The Showoff continued what has been a fairly good week by defeating Bad News Barrett in a competitive one-on-one bout Thursday night. One of the favorites to leave the Elimination Chamber with the intercontinental title, he dispatched the 2015 King of the Ring with the Zig Zag.

But the brilliance in Ziggler's performance Thursday night did not come in his work with Barrett. No, he earned winner status thanks to the promo he cut before the contest.

Cocky, confident and even bordering on arrogant, all of which fit his character to a T, Ziggler told Lana that he understood what she was doing by trying to make Rusev jealous but he was totally OK with it since she was a great kisser.

And that is an element that has been sorely missing from Ziggler over the last year or so.

Somewhere along the line, he lost the character that got him to where he is today. He was creatively neutered, for lack of a better term, losing any trace of the old Ziggler and left to try to succeed as a general wrestler who does the whole in-ring thing as good as, if not better than, everyone else.

On Thursday, fans got a little taste of the cocky and supremely confident guy they had come to love not all that long ago, and it worked.

Loser: Roman Reigns

From January onward, few Superstars have delivered as spectacularly in big-match situations as Roman Reigns has. Love or hate the guy, he has been one of the best and most consistent workers on the roster in 2015, not to mention part of some of the year's best matches.

But Thursday night again highlighted one of the biggest issues with Reigns: WWE Creative's complete and utter ignorance when it comes to booking him.

Reigns got over in the first place as a quietly charismatic guy who would unleash with great ferocity and aggression on his opponents when the bell rang. Force-feeding him what you believe are clever lines when they clearly do not fit him or his persona only makes the audience groan.

And who gets the backlash? Reigns.

Add to that the fact he was forced to stand in the background during a verbal exchange between Dean Ambrose and Kane before hitting his "believe that" catchphrase to end the segment, and it makes one wonder why he was even written into the start of the show in the first place.

Wouldn't it have been better to save his arrival for the end of the show, to counteract Seth Rollins' surprise cameo and pop the crowd even more than he already did?

It was a puzzling use of Reigns from WWE Creative, which has done little to back up the tremendous in-ring performances by a guy whom many hope becomes the face of the company for the next decade.

Loser: Stardust

No Superstar needs a character reboot more than Stardust does.

Drop the face paint and the latex bodysuit because he is dead in the water at this point. No amount of emergency reparations are going to do either Stardust or Cody Rhodes any good.

The second-generation star needs to return to being himself, the bright young worker who was one of the more consistently strong wrestlers on the roster prior to the ridiculous decision to have him rip off his brother's revolutionary character.

Losing to R-Truth for weeks on end is eating away at whatever credibility he may still have left, so it is imperative to make the change before it is too late to salvage the performer's career.
