David Martinez says that Donovan's blocking the base. Yeah, that's what he's signaling to the umpires. He dropped his knee and Garcia slid right into his knee. That's obstruction. And again, the umpires have not called this very often. Gerardo Parr is asking about it. That is absolutely obstruction. And they are not going to do anything about it. You can't challenge it.
