Back to back homeruns意思

"Back to back homeruns" is a term used in baseball to describe two consecutive home runs hit by two different players on the same team. In other words, the first player hits a home run, and then the next player to bat for the same team also hits a home run without any other batters coming to the plate in between.

This term is often used to highlight a particularly powerful performance by a team's hitters, as hitting back-to-back home runs can quickly change the momentum of a game and put a lot of runs on the board at once. It's also a sign of good teamwork and timing, as the second batter has to be ready to hit immediately after the first home run is hit, without the opportunity for the opposing team to make a pitching change or otherwise adjust their strategy.
