Las Vegas • Canelo Alvarez and Gennady Golovkin fought 24 rounds in the space of a year, with little to pick between them.
When the scorecards were totaled Saturday night, though, the judges crowned a new middleweight champion of the world — but just barely.
Alvarez won the 160-pound titles held by Golovkin by the narrowest of margins, taking a majority decision to hand the longtime champion his first loss as a pro in a spirited fight that had a sold out crowd roaring.
A year after the two fought to a draw, the second fight was almost as close.
