Split Decision (SD)
A verdict where two judges score the bout for one fighter, and the third judge scores it for the other fighter. The majority of judges pick the winner, but there is disagreement, indicating a closer fight.
Fighter A wins by **split decision** – e.g. Judge1: 115-113 A, Judge2: 116-112 A, Judge3: 114-115 B. Two votes for A vs. one for B gives Fighter A the win. Bettors holding “Fighter A by decision” tickets still win (books usually don’t differentiate SD vs UD unless explicitly bet), but it shows one judge thought Fighter B won.
