Attention will shift back to the Red Sox and the Yankees, now that Bay is off the market. The perception is that the Yankees need a left fielder, but to many analysts the team is currently strong enough to compete. More than anything, this will intensify the microscope on the Red Sox. So far this off season they've let Bay go, and tried to trade Mike Lowell to Texas. They replaced Bay with Mike Cameron, which may have saved money but is also an offensive downgrade.
The Sox were long thought to be out of the Bay sweepstakes, but now that he is about to be off the market its difficult to ignore that the Red Sox have failed to add power to a lineup that went cold at the end of 2009. So far, advantage Yankees.
