I've seen a bunch of questions about waivers, and although I definitely do not think of myself as an expert, I did read an article about them by Steve Phillips over on ESPN.com
Usually, I think the guy is an idiot (heck, look at what he did to the Mets), but this was actually a pretty informative article
Alas, it is insider only, but here are the relevant bits:
Players can change teams one of three ways on waivers:
- A player is claimed on waivers and the team awarded the claim makes a trade with the other club.
- A player is claimed on waivers and the player's team just decides to dump the claimed player on the claiming team.
- A player clears waivers, meaning that no team claimed him during the 47-hour period, and is later traded to an interested party.
Once a player goes on waivers any team can put in a claim, but the claims are awarded in order of
- League -- American League teams have dibs on AL players before the National League gets 'em and visa-versa
- Record -- When comparing two claims within the same league, the team with the worst record gets dibs.
Gammons had an article about the guys who have cleared waivers. Among the hitters that cleared were: Piazza, Griffey, Sweeney, Frank Catalanotto, Dustan Mohr, Todd Hollandsworth, Todd Walker and Edgardo Alfonzo. Sadly, one of our favorites, Adam Dunn did not clear - so we realistically have no shot at him. For those of you with insider, here's the Gammons article:
One other interesting thing to note - if a team wants to trade anyone on the 40 man roster, that player must clear waivers. So, for some of our AAA guys to be included in a waiver trade, they too would have to clear waivers. (Not bloody likely in the case of someone like Juan Cruz).
