Arizona Diamondbacks GM Josh Byrnes set the trade wire on fire tonight. He starts by acquiring Dan Haren from the Oakland Athletics in a seven player deal. All five players sent to the Athletics are prospects. Brett Anderson will be 20 in 2008 and had an outstanding season at A ball. Dana Eveland hasn't translated his low minor league walk numbers to the majors yet. Greg Smith also posts good walk and strikeout numbers in the minors. Aaron Cunningham is developing power as he rises through the minors. Carlos Gonzalez is the least impressive one of the group, but he's only 21 and already at AAA. Basically, the Athletics restocked their system with five good players.

Then Byrnes changes Valverde into Chad Qualls, Chris Burke and Juan Gutierrez. The DBacks now have two aces in Webb and Haren, and a possible third if Randy Johnson comes back. Not a bad day for the Arizona GM.

Update: I missed that Chris Carter also went to Oakland, so it was an eight-player deal.
