Jon Heyman of SI is reporting that the Milwaukee Brewers have claimed Arizona pitcher Doug Davis off waivers, where he was placed by the team. However, it's important to note that this does not necessarily mean that he will be leaving the team: it's a fairly common method used by teams, after the trading deadline, to put their players on the market. If a player is not claimed by any team he can then be dealt freely, even though the deadline passed at the end of July. [There's a good article on the process here]
The claim means that the two sides have 48 hours to work out a deal, and if nothing comes to fruition, his current team can simply pull the player off waivers, and he stays with them. Or they can let the player go, and the gaining outfit then becomes responsible for the player's salary for the rest of the season - which is no small amount in Davis's case, being about $3.5 million. The Milwaukee Journal-Sentinel reckons a trade is unlikely; it says that before the deadline, we were looking for "the equivalent of a second-round draft pick" - Davis will be a Class B free agent, so that's basically what we'd get for losing him. Nick Piecoro tends to agree, stating the team are not looking to dump salary.
We'll see what happens in the next couple of days: probably nothing at all.
