What is the origin of the sports phrase Sudden Death Overtime?

SUDDEN DEATH - "Settling a tie with a single stroke. The term comes from a variety of sports...The term was transferred to other kinds of instantaneous decision in the late 20th century..." It is used, with varying rules applied, in football, soccer, ice hockey, golf and tennis. Gamblers used the term even earlier to describe the final single throw of the dice or flip of the coin. Interestingly enough, the first appearance of the phrase 'sudden death' had nothing to do with sports. Mark Twain reported it in 1865 as a frontier expression for rotgut whiskey."
