Not sure if you are serious there, but this is how boxing scoring system works.
For your reference:
https://en.wikipedia.org/wiki/Professional_boxing#ScoringThe most widely used scoring system since the mid-twentieth century is the "10-point must system", so named because a judge "must" award ten points to at least one fighter each round (before deductions for fouls). Most rounds are scored 10-9, with 10 points for the fighter who won the round, and 9 points for the fighter the judge believes lost the round. If a round is judged to be even, it is scored 10-10. For each knockdown in a round, the judge deducts an additional point from the fighter knocked down, resulting in a 10-8 score if there is one knockdown or a 10-7 score if there are two knockdowns. If the referee instructs the judges to deduct a point for a foul, this deduction is applied after the preliminary computation. So, if a fighter wins a round, but is penalized for a foul, the score changes from 10-9 to 9-9. If that same fighter scored a knockdown in the round, the score would change from 10-8 in his favor to 9-8.
Those "10-9" simply means there is no knockdown but the judge thinks Mayweather wins the round.
