A meaningless plate appearance I watched (and wrote up) in spring training is totally consistent with what we're seeing now that he's been called up. Some pitcher got two strikes on him - one called, one sharp foul. Sano just looked so locked in at that point. He watched the next pitch go by, low, for a ball. And another out of the strike zone. And another. And ball four. But he seemed so utterly ready to punish a pitch had one been in the strike zone. Just a simple walk, in a spring game, but I was sold, both on Sano's discipline and on the fun spring training is. OK, I already knew the latter.
