Hill hasn't had the chance to progress. The problem with your theory is that if your 4 best starts are your first ones, then you get to keep your job, but if they are your 11-14th starts, and your first 4 were as bad as the other guys 5-8, then you lose out while the other guy keeps pitching. Doesn't make much sense. It's not like Hill has never gotten through a major league inning. Just look at Hill's first 4 extended outings last year. 4.1, O H, 0 R, 6 K, 2 BB 5.0, 5 H, 2 R, 5 K, 2 BB 6.0, 5 H, 2 R, 4 K, 2 BB 1.1, 7 H, 7 R, 1 K, 2 BB The difference with him is he had a full month between his first opportunity and his 2nd. He suffered a setback and then was given no chance to redeem himself later. Marshall had some decent, but hardly special outings early, suffered some setbacks, and was allowed to keep pitching. That's good. But that's the same chance Hill should have gotten.
