Luis Collazo W12 Jose A. Rivera... Little-known New Yorker Luis Collazo took a welterweight title fight on short notice in the champion's hometown and came away with a split-decision win. After a thrilling final three minutes of action, Collazo was awarded a victory over hometown hero Jose A. Rivera by scores of 115-113 (twice) and 113-115.  Boxingtalk agreed with the verdict, scoring it 115-114 for Collazo.  Rivera came forward for most of the fight but Collazo was very effective with counterpunches.  The win brings Collazo the WBA regular title at 147 pounds.  Rivera, still a contender but no longer a titlist, must now ponder whether turning down a lucrative non-title fight vs. Ricardo Mayorga last year was the right thing to do.  source: G.
