Tennis scoring system

The tennis scoring system is a way to keep track of tennis matches and tournaments. Tennis competitions are organized by tournaments that offer matches for doubles and singles. The great majority are organized as a single-elimination tournament, with competitors being eliminated after one loss, and the overall winner being the last competitor without a loss. Optimally, such tournaments have a number of competitors equal to a power of two in order to fully fill out a single-elimination bracket. In many professional and top-level amateur events, the brackets are seeded according to a recognized ranking system, in order to keep the best players in the field from facing each other until as late in the tournament as possible; additionally, if byes are necessary because of a less-than-full bracket, those byes in the first round are usually given to the highest-seeded competitors.
