In baseball, 30 30 refers to a significant achievement by a player who hits both 30 home runs and steals 30 bases in a single season. This rare feat showcases the player's exceptional power and speed. It demonstrates that the player is not only hitting the ball out of the park but also successfully stealing bases to advance in the game. For example, let's say there's a player named Alex. In a season, Alex hits 30 home runs, meaning he hits the ball in such a way that it goes over the outfield walls and he can score a run. In addition to his impressive power hitting, Alex also steals 30 bases throughout the same season. This means that he successfully advances to the next base while the opposing team tries to catch him out. Hitting 30 home runs or stealing 30 bases individually is already quite an accomplishment in baseball. So when a player achieves both in a single season, it is a notable milestone and demonstrates their exceptional skills in both power hitting and base stealing.
