Raw women's championship (30-minute Iron Man match): Charlotte Flair def. Sasha Banks 3-2 in overtime (34:45)

Charlotte Flair and Sasha Banks added a new chapter to the growing legend of their 2016 rivalry on Sunday night -- closing out the year's final pay-per-view with a 30-minute Iron Man match that needed extra time to declare a winner.

With Banks bleeding heavily from her nose and mouth during overtime, Charlotte forced the WWE Raw women's champion to tap out via the Figure 8 leg lock to win the match three falls to two at Roadblock: End of the Line in Pittsburgh, Pennsylvania.

Charlotte regained the title as the belt changed hands for the sixth time since the WWE's latest brand split in July. All three of Banks' victories during that stretch have come on Raw, while all of Charlotte's have taken place on PPV. The victory extended Charlotte's unbeaten streak in pay-per-view singles to 15-0 -- the best mark ever recorded by a WWE superstar.

Sunday's match was much slower and methodical than their recent physical and violent meetings at Summer Slam and Hell in a Cell. While the PPG Paints Arena crowd was slow to heat up, Charlotte and Banks gave them plenty of reason to as their largely technical affair heated up late.

Charlotte recorded the first fall with 10 minutes, 46 seconds remaining when she pinned Banks after connecting with her Natural Selection finishing move off the top rope. Banks countered two minutes later to even things up with a sneaky roll-up for a three count.

After Charlotte missed a moonsault minutes later, Banks took the lead with 6:40 remaining when she forced Charlotte to tap to her Banks Statement submission.

The end of regulation saw Charlotte, who was trailing 2-1, focused exclusively on the left knee of Banks. She applied her Figure 8 leg lock in the center of the ring with exactly 2:00 to go, and forced Banks to dramatically tap out with just seconds to spare to even things up.

After referee Chad Patton called for a sudden-death overtime period, Charlotte continued to attack Banks' knee before the bell sounded to start the extra session.

Banks initially had Charlotte trapped in a Banks Statement but Charlotte broke fee and reserved the move into a Figure 4 again, before arching her back to form the bridge of the Figure 8 to earn the submission win as Banks' face become covered with blood following a blow to the face.

The bout marked the 11th Iron Man match in WWE history and just the second female match. Banks and Bayley took part in a 30-minute Iron Man match at NXT Takeover: Respect in 2015.
