It seems to be paying off. The rate of shattered bats has dropped for the past four years. Around 1,200 bats shattered in players' hands last year, compared to 2,500 in 2008. The average "multipiece failures per game," i.e. the number of bats that shatter into a million shrapnel pieces, has gone down from 1.0 in 2008 to 0.47 to 2013.
