It seems the Yankees have done some research on the subject and have figured out that the missing link between them and a pennant is OF/1B Eric Hinske. The Yankees swung a deal for Hinske today giving up assorted crap and getting back Hinske and cash.
Hinske was part of the 2007 World Series champion Red Sox and the 2008 AL pennant winning Tampa Rays. He hasn't done much in limited playing time with the Pirates, slugging only .368 in 106 at bats, but he does strengthen the Yankee bench in the wake of the news that Xavier Nady will be out for the season.
The Yankees only gave up 23 year old right-hander Casey Erickson and 23 year old outfielder Eric Fryer. Erickson has pitched well for the Charleston Sea Dogs, but at 23 he hasn't moved above Low-A ball yet. Same goes for Fryer who was acquired from the Brewers in the off-season for Chase Wright.
It's a low cost, low reward move for the Yankees. Hinske gives them a decent pinch hitter and someone who can spell either Johnny Damon or Nick Swisher in the outfield. It's a move that can only help them and if Hinske flops then the Yanks have enough time before the deadline to try something else.
