The Yankees have acquired OF Xavier Nady and RP Damaso Marte from the Pittsburgh Pirates for Jose Tabata, Ros Ohlendorf, Phil Coke, and George Kontos.
Jimmy Dugan's Take - At first glance, this looks like a lot to give up for a couple of 'band-aids', but I like this move. Both Nady and Marte could be a part of the 2009 roster, with Nady under contract, and the latter having a $6 million option.
As for what the Yankees are sending to the Bucs, yes, they are giving up some value. Tabata has loads of potential, but his downside has become more evident in 2008. Not only has his power continued to disappoint, his attitude is now in question. Ohlendorf is at best a servicable reliever. Kontos and Coke are similar as they both have solid minor league numbers, but are not considered in the Hughes-Kennedy-Horne-Melancon or even Marquez level of Yankee pitching prospect.
UPDATE - Coke and Kontos have been replaced by minor league pitchers Daniel McCutchen and Jeff Karstens. While most experts have McCutchen rated higher than both Coke and Kontos, Karstens is a spare part - and horribly ugly to boot. Still a good trade.
