Previous research neglects to consider additional sources of moral hazard in baseball beyond the designated hitter rule. Using a game-level analysis similar to Bradbury and Drinen (2006), we find that an additional National League relief pitcher leads to more hit batsmen than an additional American League relief pitcher and that the number of games remaining in the National League has a smaller positive effect on the number of hit batsmen than the number of games remaining in the American League, though the latter relationship is economically small.Both results, however, imply additional avenues by which moral hazard emerges.JEL classifications: D81, L83
