I can agree with idea of him doing this when he leads off the inning. And, the way things have gone thus far, he's been starting the inning more than I'd like to see (yeah, I'm looking at you Loretta). In fact, I'm getting outright sick of seeing the shift, and I'd like to see the Sox make teams pay for it, so I can think of other scenarios where they ought to take advantage. Of course, for them to pay the full price, they need the full Manny threat behind Papi, and I don't think he's all the way back yet. Once he is, they should consider doing it more often to keep teams honest.
