LIVORNO, Italy — Sumbu Kalambay, a naturalized Italian, saved strength for the late rounds and won the vacant World Boxing Assn. middleweight title Friday night with a 15-round unanimous decision over Iran Barkley.
Judges scored the fight 147-140, 147-140 and 147-142, giving Kalambay the title left vacant when Sugar Ray Leonard retired.
Kalambay, 159, improved to 43-3-1. Barkley, 153, of New York, spent much of the day attempting to add weight. He is 22-4.
Kalambay, 31, used a conservative style, and Barkley, 27, landed several damaging lefts. By the 11th round, Barkley showed signs of fatigue, and Kalambay scored with punishing rights.
The American looked stunned toward the end of the 12th, and the ring doctor checked his left eyebrow, prone to bleeding in past bouts.
