Echo Arena, Liverpool, Merseyside - Tony Bellew (21-2-1, 13KOs) made his splash at cruiserweight with a twelfth round knockout of Valery Brudov (41-5, 28KOs) to win the vacant WBO International title. It was Bellew's first bout at the cruiserweight limit, after moving up from 175-pounds following November's knockout loss to WBC champion Adonis Stevenson.
Perennial (or even eternal, as some followers of the game would point out) welterweight contender Kell Brook (32-0, 22 KOs) continued to dismantle one opponent after another with yet another effective stoppage - this time of brave but bitterly overmatched Mexican Alvaro Robles (17-3, 15 KOs). The Special One, 27, halted Robles on his feet at 1:35 of the eighth round after a horrid beating.
Meanwhile, two-time world title challenger Kevin Mitchell moved closer to a third shot at one of the four major lightweight belts after stopping Mikheil Avakyan inside two rounds.
The 22-year-old Georgian was overwhelmed from the outset and Londoner Mitchell was able to land his shots at will against an ungainly foe.
Avakyan was dropped twice in the first session to some rudimentary blows and after the youngster was sent down in the first minute of the second to a sharp combination referee Steve Gray had seen enough.
A shot at IBF lightweight champion Miguel Vazquez could be next for Mitchell on the Froch-Groves undercard on May 31, according to promoter Eddie Hearn.
