Non-steroid related baseball news: Dan Haren traded

These players that Oakland got from the Diamondback in exchange for Dan Haren had better be some good prospects. Otherwise, why trade away the AL All-Star game starter when he still has three years left on his contract for an average of less than $5.5 million a year? If this was Haren’s last year under contract and would be a free agent in 2008, then I could understand the trade. But Haren won’t be a free agent until 2010 so why wouldn’t Billy Beane keep him for two more years?
