Update 4:16: The Yankees have also acquired Martin Prado from the Diamondbacks, according to Jack Curry of the YES Network. Prado is batting .270/.317/.370 with five homers this season.
Drew, 31, signed a one-year deal with the Red Sox in late May. He is really struggling, hitting .176/.255/.328 in 39 games this season. Drew had a solid season last year, batting .253/.333/.443.
This is a puzzling deal for the Yankees but a good one for Boston. They get salary relief and will get Kelly Johnson out of it. The Yankees struck out in their search for a big bat today, but they may have a second baseman for the rest of the year.
The Red Sox are tearing down everything right now. They have now dealt 4/5 of their Opening Day rotation, and have shed some more salary. However, they have recovered some other pieces that could be useful in the years to come.
