The Oakland A's sent established pitcher Trevor Cahill and reliever Craig Breslow to the Arizona Diamondbacks in exchange for top pitching prospect Jarrod Parker, OF prospect Collin Cowgill and relief prospect Ryan Cook, according to the league. Matt Eddy of Baseball America has a full scouting report on all the players involved. Nick Piecoro of the Arizona Republic profiles the trade from the Diamondbacks side.
Parker is the key to this trade, immediately becoming the top prospect in the A's farm system. A potential ace, Parker is a full season removed from Tommy John surgery and is still regaining his command, especially with his slider.
Reactions to the trade have varied. Kevin Goldstein thinks it's a "really good trade for the A's," while Keith Law of ESPN.com doesn't think the A's got enough in return. Zach Sanders of FanGraphs.com likes the deal for the Diamondbacks as well, and Athletics Nation thinks the A's got back "roughly 60%" of Cahill's value.
