Ground Ball Hits are batted balls that have a trajectory in which the ball rolls or bounces on the ground. These players hit the most balls into play that’s classified as a ground ball (that can result in a hit, ground out, fielder’s choice, or reach on error). Ground ball leaders usually do not have a lot of power and some (though not all) try to hit the ball on the ground and utilize their speed which can often be the best chance they have to reach base. Ground ball leaders are often good contact hitters and less likely to strike out than the average batter. Ground ball leaders often have a higher than average BABIP (batting average on balls in play) as many will use their speed to beat out infield hits that may not have resulted in hits for a slower runner.
Also referred to as a "Grounder."
