This particular regulation, often implemented in recreational softball leagues, limits the number of over-the-fence hits a team can achieve per game. Typically, once a team hits two over-the-fence balls, any subsequent such hit is treated as a single or an out, depending on league-specific guidelines. For example, a team might hit two home runs in the first inning. If they hit another in the second, that ball may be ruled a single instead of a home run, preventing one team from dominating the game through excessive power hitting.
The primary benefit of restricting over-the-fence hits is to promote a more balanced and competitive environment. It discourages an over-reliance on power hitting and encourages teams to develop other aspects of their game, such as base running, small ball tactics, and defensive strategies. This rule aims to increase player engagement and team diversity by limiting the impact that a few strong hitters can have on the overall outcome. Historically, such regulations have arisen in response to concerns about safety in smaller playing fields and to ensure that a wider range of skillsets are valued.
