Why Do Managers Prefer Ground-Ball Relievers With Runners On Base?
One ground ball can erase more than one problem.
Managers prefer ground-ball relievers because ground balls create double-play opportunities and are less likely to score inherited runners than deep fly balls or extra-base hits.
Inherited runners create immediate pressure. In those situations, preventing a ball from reaching the outfield often becomes the highest priority.
Ground-ball pitchers naturally fit that goal. Their pitch movement encourages hitters to drive the ball into the ground rather than into the air.
A well-timed ground ball can produce a double play and end an inning instantly. Even when it does not, ground balls often limit runner advancement.
Bullpen decisions are heavily influenced by game context. Managers frequently select relievers based not only on talent but also on the specific type of contact they tend to generate.
