After moving Koji to Texas, Andy MacPhail and the Orioles weren’t finished last night.  In the late hours of Saturday, Derrek Lee was traded to the Pittsburgh Pirates for Single-A first baseman Aaron Baker.

Lee sat out of game two of the double header in New York last night and the rumors about the deal were circulating all evening.

Baker is a 23 year old prospect who will reportedly be sent to Single-A Frederick when he arrives to the Baltimore.  Here’s what Ben Nicholson Smith of had to say about the O’s newest acquisition:

Baker, 23, has a .285/.353/.474 line with 15 homers in Class A Bradenton this year. The 2009 draft pick did not crack Baseball America’s preseason list of the Pirates’ top 30 prospects.

The Orioles likely would have lost Lee at the end of the season as he signed a one year contract for 2011. It’s still tough to believe that the Pirates are buyers.
