WWE Fastlane 2021: 5 Potential finishes for Nia Jax and Shayna Baszler vs Sasha Banks and Bianca Belair 

Nia Jax came up short in her quest to become SmackDown Women's Champion last night when her Women's Tag Team partner cost her the match. The loss comes two days ahead of their title defense at WWE Fastlane.

Jax was locked in The Bank Statement when Bianca Belair and Shayna Baszler invaded the ring. Baszler looked to kick The Boss in the face but instead, she kicked her own partner and left her to be pinned by the Champion

Later in the night, Baszler took on Bianca Belair and both Sasha Banks and Nia Jax walked out, leaving their partners to go it alone. The two women then were attacked by Natalya and Tamina, who have been looking to send a message to the Women's Division.

There are several potential finishes that could take place for the WWE Women's Tag Team Championship match between these four high-profile women at Fastlane.

#5. Nia Jax and Shayna Baszler retain the Women's Tag Team Championships at Fastlane

Nia Jax and Shayna Baszler won the Women's Tag Team Championships back from Asuka and Charlotte Flair at The Royal Rumble. They have already beaten Sasha Banks and Bianca Belair.

The two women came up short in their quest to become champions back at Elimination Chamber. Bianca Belair and Sasha Banks are far from on the same page. The two women are set to collide for the SmackDown Women's Championship in just over three weeks' time at WrestleMania.

The EST of WWE made the decision to challenge The Boss at WrestleMania following her Royal Rumble victory back in January. The two women have since been able to remain civil as part of this feud. This could all change after Fastlane when the build-up to WrestleMania begins and they are forced onto opposite sides of the ring.

The fact that Banks and Belair are a thrown-together team could work in Jax and Baszler's favor. The champs know each other well and should be able to overcome the challenge of the challengers if they don't allow their differences to get in the way at Fastlane.

#4. Tamina and Natalya interfere and try to send a message to the Women's Division again at Fastlane

Heading into Fastlane, Tamina and Natalya have joined forces. Last night on SmackDown, the two women made it clear that they mean business ahead of Fastlane when they attacked Shayna Baszler and Bianca Belair.

Nattie and Tamina come from wrestling families and believe that they deserve much more than they have been given in the Women's Division. This could be why they felt the need to attack Baszler and Belair.

Of course, the two women could be making a statement because they haven't been handed a Women's Tag Team Championship match. Sasha Banks and Bianca Belair came up short at Elimination Chamber but have been given a second opportunity whilst Tamina and Natalya remain overlooked.

Could the two women once again insert themselves into Sunday night's match at Fastlane and push for a shot at the Women's Tag Team Championships at WrestleMania?

#3. Bianca Belair and Sasha Banks become Women's Tag Team Champions at Fastlane

Bianca Belair and Sasha Banks have been able to remain on the same page throughout their time working together on SmackDown, whilst building towards this match at Fastlane.

There have been moments where the two women have made it clear that they are only working together for the championships. When they are on the same page, they have made a formidable team.

Despite the fact that the two women will be on opposite sides of the ring at WrestleMania, stranger things have happened in WWE than Belair and Banks walking out as Women's Tag Team Champions.

After all, Shawn Michaels and John Cena were Tag Team Champions when they faced off at WrestleMania. Michaels went on to cost the team the titles a day later on RAW.

Baszler and Jax are having a few issues remaining on the same page at present and The Boss and The EST of WWE could take advantage of that at Fastlane to become champions heading into WrestleMania.

#2. Reginald involves himself in the match and sways the outcome of the championships at Fastlane

Reginald may or may not be present this weekend at Fastlane. The former NXT star was given a break and a spa day this week which allowed him to miss Friday Night SmackDown.

Of course, Reginald wasn't needed since Shayna Baszler caused Jax to be unable to become SmackDown Women's Champion. However, he could return this weekend and again be the difference-maker.

Reginald was the reason why Banks and Belair came up short at Elimination Chamber. He provided the distraction but has made it clear that he wants to be on Sasha's team despite being recruited by Nia Jax and moved over to Monday Night RAW.

It will be interesting to see if Reginald can help Jax and Shayna Baszler to retain or if he decides that Fastlane is the best time to jump ship and help The Boss to become Two Belts Banks again.

#1. Shayna Baszler and Nia Jax finally implode which leads to the two women entering a feud following Fastlane

Last night's episode of SmackDown laid down quite the tease ahead of Sunday night's Women's Tag Team Championship match at Fastlane.

Shayna Baszler inadvertently kicked her own partner in the face and cost her the Women's Championship. Jax then walked out on Baszler during her match with Bianca Belair. The two women were then attacked by Tamina and Natalya but Jax didn't go on to make another appearance as part of the show.

There have been teases that the two women could go their separate ways a number of times. If there's a moment where a move goes wrong or either star inadvertently hits the other, it could easily spark the end of their union at Fastlane.

The two women are hanging on by a thread at present. It's easy to see a loss at Fastlane being enough to kickstart a feud between the former friends heading into WrestleMania.
