RS (runs support)

Run support, often abbreviated as RS, is a term in baseball that refers to the number of runs scored by a club while a pitcher is on the mound . It’s a crucial indicator of how much offensive production a pitcher receives from his teammates. In other words, it’s a measure of how well a team supports its pitcher with runs, which can significantly influence a pitcher’s performance.

For instance, a pitcher would be considered to have received five runs of support if his team scores five runs during his six innings on the mound. The amount of run support a pitcher receives has a profound impact on his performance, often determining his win-loss record. Therefore, this statistic is commonly used to put a pitcher’s win-loss record in context, making it a significant aspect of baseball analysis.

Run support, a concept used in baseball analysis rather than an official metric by MLB, helps us understand the interplay between a team’s offense and its pitching staff. It’s clear that a team’s chances of winning a game are significantly bolstered when they score more runs to support their pitcher. This underscores the crucial role of offensive production in a team’s victory, a key insight for baseball fans and analysts.
