In a meeting between the two undefeated champions, widely regarded as the best two fighters at 140lbs, Taylor sealed a majority decision win in a Fight of the Year candidate at the O2 Arena in London.
The victory sees the Edinburgh fighter walk away with 50 percent of the world title gold on offer at super-lightweight – with Jose Ramirez holding the WBO and WBC belts.
Fight fans were treated to an epic unification bout recently when Errol Spence Jr edged past Shawn Porter in a welterweight classic one month ago.
That was eclipsed as Taylor and Prograis served up an enthralling contest – with two elite operators going to war in an absorbing exhibition of skill and determination.
Prograis looked the more composed fighter in the opening rounds, exhibiting the superb head movement and impressive shot selection of shuddering body shots, crisp jabs and stiff uppercuts that had seen him remain undefeated in 24 professional bouts.
Taylor grew into the contest considerably however, making the fight uncomfortable for the skilful American and slowing him down with shuddering body blows of his own in the seventh and eighth rounds.
Momentum had swung in Taylor’s favour and the Scot, two years younger than his opponent, made use of his superior physical strength to stay on top, finding his target with impressive shots that stirred up the home crowd.
Prograis fought back in an absorbing contest with Taylor’s eye almost swollen shut as a result of the damage he took, but a strong 10th round from the Scot ensured he retained momentum.
Taylor secured a 114-114, 115-113, 117-112 win on the judges’ scorecards, dedicating the victory to his father-in-law who died last month.
Lee Selby outpointed three-weight world champion Ricky Burns in a compelling lightweight contest while Lawrence Okolie and Conor Benn extended their undefeated records.
Josh Taylor has done it! He wins an absolute classic and adds the WBA title to his collection.
Josh Taylor beats Regis Prograis via majority decision!
