Just a guess. They kept quiet to not tip off other teams and waited until now to confirm it because it became obvious to the world. They kept on trying to convince teams that he was just getting timing back, was crushing the ball in BP, etc. . . so they would have some fear of throwing lefties at us. They want righties because our best two hitters have been Harper and LaR, with Lombo our best OBP guy. I'd be curious about our offense v. RHP and v. LHP. [edit - I checked it - It looks like both in terms of wOBA and OPS, we are slightly better v. RHP.]
