It's rare for two contending teams to swap players, especially during the season.
However the Giants, with their rich arsenal of arms and the Red Sox, buoyed by a deep offense, are a study of contrasts. They each have an excess (if such a thing ever exists) of what the other wants. And therein lies the roots and the reality for an exchange to occur between these two top-of-the-line franchises.
For both teams, injuries have hit them in their respective weak spots. The Red Sox rotation and bullpen have both taken hits.The Giants are particularly hamstrung at the plate without Buster Posey, and for a few more weeks, Pablo Sandoval.
Here are a few players on each team that the other might be interested in as a means of plugging some holes, not only in present but also over the long haul.
