Since players can't control the location of their ground balls, luck is a major factor regarding whether or not they end up with a hit (generally, a single). It turns out that almost all batters are subject to this "rule," and the mean of ground balls that end up as hits tends to hover right around 25% (or .250).

Sorry... I was confusing BABIP and BHIP (singles average):

Singles Average (BHIPx%)- An indicator which measures the percentage of batted balls which are hit into play and are subsequently registered as singles (Singles/(AB-K-2B-3B-HR)). The typical singles rate for the entire MLB universe is around .250. Every year there are outliers that hit significantly below or significantly above this average...of these, 80 to 85% are able to reverse that trend the following season. Using this historical indicator, we can surmise (based on batting average) which players will have a comeback or drop-off season.

Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
