the.com/home run

means A hit that sends the ball out of play (or at least far enough) to let the batter round all the bases and score in one go, no sprinting required.

from From baseball's 19th-century vocabulary, where a 'run' was already the word for a scored point — a batter 'ran home' through first, second, third, and back to home plate. Add 'home,' the base where the run completes, and you get a hit so clean it guarantees the whole circuit. The figurative sense — any unqualified success, a 'home run' of a pitch meeting or a business deal — took off in the 20th century, riding the sport's popularity into everyday speech.
