Via Jayson Stark: MLB and the MLBPA are working on an agreement that would “clarify” the new home plate collision rules, specifically for plays like this. An official announcement is expected soon. Stark says the clarification “would remind umpires that while the intent of the rule was to protect catchers from violent collisions at the plate, the wording was not intended to be interpreted so strictly that it would allow runners to be called safe on a technicality if the throw had beaten them to the plate by a substantial margin.”
As Dave Brown put it the other day, home plate has become the twilight zone. No one really seems to know what’s happening on plays at the plate anymore and they’re often followed with reviews and arguments and confusion. Hopefully whatever MLB and MLBPA are working on will clear up some things, but I still expect there to be some bumps in the road. I think the spirit of the rule is great — avoid turning catchers’ brains into mush, basically — but the new rule is clearly a work in progress. There has definitely been a league-wide learning curve in year one.
