HS Fed - Catcher Obstruction question

[DG]

But, MLBUM and PBUC do not cover near the number of issues topics that JEA and J/R do. JEA is not readily available, it has been out of print for some time. MLBUM is only available to ML umpires, or if you know one. J/R and PBUC can be purchased any time. PBUC and MLBUM are nearly identical if not exactly identical in rulings. So if you want to get good interpretations books get PBUC and J/R and then get Carl's Baseball Rules Difference (BRD) to get differences between OBR, NCAA and FED.
