On the surface, the Grissom watch is just silly because he's played just 16 games. What's the point?
Well the point is that the Sox brain trust are paying Chris Sale's freaking salary of $17M while he starts for the Atlanta Braves and so far has the highest pitching WAR on the Braves and the 2d most IP. That is nothing less than extraordinary and demands that we question what the Sox got in return.
The catch, of course, is that the Sox have 6 years of control over Grissom in addition to his being a pretty good prospect a year or two ago. So, as moonslav and others insist, it's way, way, way, way too early to pass judgment on the trade.
But not for me. I'll give Grissom another 2-3 months, which is about what Pedey had as a rookie in 2007 (and having played in 31 MLB games in 2006) before he showed how good he was.
And maybe I'll give Grissom the whole season because no way, no how can he fix this lineup with his bat.
And as for losing Sale, while I hate it, after 51 games the Sox still have the 2d best ERA in MLB (but the Phillies, ERA 3.11, are about to pass them). 3d is still pretty amazing.
