For three minor leaguers, Tim Kurkjian talking on ESPN right now. More when I get the links.

[update] Kurkjian did not say who the players acquired were, though the host did quesiton why the Phillies wanted a pitcher with a 5 ERA and a 1.5 WHIP

[update 2] From Rotoworld:

ESPN's Buster Olney says the Phillies have acquire Joe Blanton from the A's for three minor leaguers.
No word yet on the prospect, but the A's needed to get either Carlos Carrasco or Adrian Cardenas here. Infielder Jason Donald and catcher Lou Marson are the Phillies' next-best prospects. Getting both Carrasco and Donald would have been a coup for the A's. What this does for the Phillies' plans for Brett Myers is unclear. If Myers would be happy in a setup role, it'd now make sense for the Phillies to convert him.

[update 3] For those curious, you can find Buster Onley's original "Blanton will be traded" video here.

[update 4] The Links have arrived. SF Gate confirms the Blanton trade, and ESPN reveals who we got in the deal.

The Athletics get second baseman Adrian Cardenas, pitcher Josh Outman and outfielder Matthew Spencer, all minor leaguers.

[update 5] Stats for all!
