NEW YORK — Katie Taylor and Amanda Serrano will complete their historic trilogy later Friday night when they collide at Madison Square Garden in New York City.

Before that, however, there's an stacked undercard for boxing fans to sink their teeth in.

Alycia Baumgardner, Chantelle Cameron, Savannah Marshall and Ellie Scotney will all be in action.

Spain’s Jennifer Miranda showed up to fight against undisputed junior lightweight champion Alycia Baumgardner, but tough wasn’t enough as “The Bomb” retained her titles via 10-round unanimous decision in the co-main event.

Baumgardner (16-1, 1 NC, 7 KOs) was calm, cool and collected with her attacks in the first two rounds, as the awkward Miranda (12-1, 1 KO) tried unsuccessfully to goad her into a scrap. The champion wasn’t buying it, but in the third she began upping her work rate with pot shots and close-range combinations. It was during these inside exchanges where Baumgardner excelled against her bigger foe, who nonetheless wasn’t going anywhere as the bout approached the midway mark.

Miranda’s wild rushes got wilder in the sixth and seventh rounds, and Baumgardner responded with some of her best work as she countered her while simultaneously steering clear of incoming head-butts.

To her credit, Miranda never stopped pressing and trying to win, but she didn’t have the power to get the respect or attention of Baumgardner, who kept all the belts at 130 pounds in her possession via scores of 98-92 (twice) and 97-93.

In a super middleweight upset, WBO champion Shadasia Green battled back from an early point deduction to win a hard-fought 10-round split decision over Savannah Marshall, taking the Brit’s IBF and The Ring titles in the process.

Scores were 95-94 and 96-93 for Green (16-1, 11 KOs). The only loss for Marshall (13-2, 10 KOs), who won on one card, 96-93, had been to Claressa Shields.

Neither fighter shied away from letting bombs fly in the early going, but the wild punches largely missed their mark as they settled into the fight. Clinching soon became an issue, though, with referee Thomas Taylor warning Green twice in the second stanza.

When Marshall wasn’t getting her inside attacks smothered, she was able to stay busy and effective from long range.

In the fourth, Green was docked a point for holding, putting her in an early hole on the scorecards.

The New Jersey native finally gave the local crowd something to cheer about in the fifth as she drilled Marshall with several hard shots that certainly got her attention and marked a shift in the fight as the exchanges got cleaner and the rounds got closer.

Marshall landed one of her best punches in the eighth when she scored with a flush right hand, but Green just stared back at her foe in response. It was a point scorer, though, and an important one heading into the final two frames.

They scrapped on even terms to the end.

London’s Ellie Scotney kept her unbeaten record and her IBF, WBO and Ring magazine titles intact in junior featherweight action as she outboxed Yamileth Mercado and took the Chihuahua native’s WBC belt in the opener of the four-fight main card.

Mercado (24-4, 5 KOs) found out early that Scotney’s speed was going to be an issue, but with the Brit not possessing fight-changing power, the Mexican tried wild aggression to get the better of her opponent. Her wide and wild shots didn’t serve her well, though, as Scotney (10-0) either stepped out of range or countered with little effort.

In the fifth, Mercado’s increasing frustration was evident. Scotney went back to her corner with a cut over her left eye, but it was Mercado who ended the frame with her own cut to deal with as she had to be wondering what she needed to do to get into the fight.

Those answers never came, and while the bout went the distance, the final scores of 100-90 and 98-92 (twice) were never in doubt.

Australia’s Cherneka Johnson arrived with the WBA bantamweight title, and after an impressive stoppage of Shurretta Metcalf she left the Madison Square Garden ring with her IBF belt and the vacant WBC and WBO belts, too.

The end came when referee Charlie Fitch halted the bout two seconds into the ninth round.

Johnson’s steady pressure baffled Metcalf immediately, and the difference in technique between the two was evident. Metcalf, who was dropped in the fourth round and rocked on a number of occasions, didn’t have her legs under her throughout the bout, which led to her return fire having no effect on the soon-to-be undisputed champion at 118 pounds.

In response, Fitch and the ringside physician kept their eyes closely on the action until finally stopping the fight in spite of Metcalf’s protests.

Chantelle Cameron kept her hopes for a rubber match with Katie Taylor alive as she scored a clear-cut 10-round unanimous decision over Jessica Camara in defense of her interim WBC junior welterweight title.

Scores were 99-91, 98-92, 99-91 for Northampton’s Cameron.

Montreal’s Camara (14-4-1, 3 KOs) took the fight to Cameron (21-1, 8 KOs) at the start and she refused to back down from any exchanges with the Brit. The unfortunate part for the Canadian was that Cameron was more than willing to brawl at close range, and what resulted was compelling — but one-sided — action throughout.

The crisper punches continued coming from Cameron, and the pace of the fight began to take its toll on Camara, whose face showed the wear of battle. After the seventh round, Camara was on wobbly legs as she returned to the corner, prompting a visit from the ringside physician. Camara was cleared to continue,and she gamely fought on, but it was all Cameron down the stretch

Junior featherweight contender Ramla Ali survived a spirited effort from Brazil’s Lila Furtado before emerging victorious via unanimous decision.

Scores in the eight-rounder were 77-75 twice and 78-74 for Somalia’s Ali.

Furtado (11-3, 2 KOs) came out firing from the opening bell, swarming Ali (10-2) throughout the bout. After taking some time to get acclimated to the pace, Ali began landing good counters on the inside, nearly dropping Furtado in the second round. That was as close as the fight came to producing a knockdown, and Ali’s cleaner shots likely made a positive impression on the judges, even if the crowd didn’t agree with the decision.

In the opener at Madison Square Garden, two-time Canadian Olympian Tamm Thibeault put herself in line for a shot at the vacant WBA middleweight title with a fifth-round TKO win over previously unbeaten Pittsburgh native Mary Casamassa.

The WBA final eliminator was scheduled for eight three-minute rounds.

In control from the start, Quebec’s Thibeault dropped her foe in the opening round, and while Casamassa was game she was outgunned. The 2020 and '24 Olympian picked up the pace in the fourth, and it was a matter of time until the end came at 2:18 of Round 5, with referee Charlie Fitch stepping in after an unanswered barrage of punches from Thibeault.

Thibeault moves to 3-0 with 2 KOs. Casamassa falls to 6-1 with 1 KO.
