Tito has made some questionable calls regarding the bullpen, and I'm not a huge fan of his usage of Foulke in so many non-save situations. However, he has done a decent job, and I cant really think of too many games that we've really lost because of a decision of his. (one or two come to mind, but thats it).
As for Embree, for some reason he is struggling at home with a 5.56 ERA, but he is fine on the road with a 3.29 ERA. This is a little bit strange, but it shows that something isn't horribly wrong with his delivery at least. He should snap back into it, and if he doesnt, no worries. Williamson is back with a vengeance.
