NEW YORK – Alycia Baumgardner left no doubt whatsoever about the outcome of this 130-pound title fight.

Baumgardner dropped Elhem Mekhaled twice during the fourth round, hurt her badly during the seventh round and won their 10-round title unification bout by unanimous decision at Madison Square Garden’s Hulu Theater. The 28-year-old Baumgardner became women’s boxing’s fully unified junior lightweight champion by defeating France’s Mekhaled, whose toughness made what was a one-sided fight on the scorecards entertaining.

Judges Robin Taylor (99-89), Eric Marlinski (99-89) and Ron Paolillo (98-90) all scored the bout for Baumgardner by big margins.

Baumgardner (14-1, 7 KOs), of Bingham Farms, Michigan, retained her IBF, IBO, WBC and WBO 130-pound championships and won the WBA belt that was vacant before she defeated Mekhaled. In her previous appearance, Baumgardner edged rival Mikaela Mayer (17-1, 5 KOs) by split decision in their 10-round championship unification fight October 15 at O2 Arena in London.

Mayer, who watched Baumgardner beat Mekhaled from a ringside seat, wants a rematch as soon as possible.
