Overview
A line drive is a batted ball that travels on a low, sharp trajectory, occupying the middle ground between ground balls and fly balls. Line drives are the batted-ball type most likely to result in hits: statistically, approximately 70% become hits, far exceeding the hit rates of ground balls (roughly 25%) and fly balls (roughly 20%). The high hit probability stems from the ball's speed and trajectory. A hard-hit ball on a flat plane gives fielders minimal reaction time and easily splits defensive gaps. Unlike fly balls, line drives lack the hang time that allows outfielders to reach the landing spot. For hitters, producing line drives signals high-quality contact. Generating sharp liners requires precisely squaring the ball on the bat's sweet spot and returning it at the optimal angle. Ichiro Suzuki built his legendary batting average on a prolific output of line drives, a style celebrated as 'the art of the liner.' In modern analytics, line-drive rate (the percentage of batted balls classified as line drives) has become an important metric for evaluating hitter quality.
