I had this one pegged all wrong, but in hindsight, it makes sense. They had to clear a 40-man spot for Berroa, and Terry Tiffee is more expendable if he should get claimed off waivers by another club. This might mean Hu and Berroa split time at SS until Furcal comes back, which he is TENTATIVELY expected to do on July 17 at Cincinnati, at which point Hu is almost certain to go back to Triple-A. I explain this every time someone gets designated for assignment, but in case you missed it, that means the club has 10 days to trade, release or outright that player. Before he can be released or outrighted, he must clear waivers, and that means he has to be ON waivers for three full business days without being claimed by another club. The Dodgers can waive him at any point during the 10-day period, they don’t have to do it immediately. I’m not sure whether Tiffee has ever been outrighted before, but if it’s at least the player’s second outright, he has the right to refuse the assignment and become a free agent. … The Tiffee move means the Dodgers reduce the number of Arkansas natives on their roster from one to zero.
