Best Championship Performance ESPY Award

The Best Championship Performance ESPY Award was presented in 2001 and has been presented annually since 2004 to the sportsperson, irrespective of nationality, gender, or sport contested, adjudged to have given the best performance in a single championship game, series, or tournament played in a given calendar year; the award technically devolves on both the sportsperson achieving a performance and the performance itself.
For those team sports contested professionally in North America or collegiately in the United States, "championship" performances are those that occur in an ultimate game and match or ultimate series of games, whilst such performances in international team sports are those that occur in the ultimate game of a premier competition or in a world championship organized by a recognized governing body. Individual "championship" performances are those occurring in the ultimate game or match of a significant championship or in the series of games or matches that compose a single significant championship tournament or event (in golf and tennis, respectively, e.g., a major championship or Grand Slam tournament). 
Balloting for the award is conducted over the Internet by fans from amongst between three and five choices selected by the ESPN Select Nominating Committee. Through the 2001 iteration of the ESPY Awards, ceremonies were conducted in February of each year to honor achievements over the previous calendar year; awards presented thereafter are conferred in June and reflect performance from the June previous.
There was no award presented in 2019 or 2020.
