Ray's issues are entirely between his ears. Frankly, I think he should be moved to the pen... His stuff is plenty good enough to be a closer... of course, since he is a mental midget who knows if he could handle the pressures of that role.
At present, he can't make it into the 5th inning in less than 80 pitches. He may have done that once or twice this year and IIRC, he actually did quite well in those rare instances.
But come the 4th and 5th inning, when hitters are making adjustments and he begins to tire, he essentially starts tossing batting practice. His velocity is gone and he loses the ability to locate his slider.
It's all now bigtime mental for him. When he reaches the 3rd inning and he's pushing 50-60 pitches, I have no doubt he's worrying about pitchcount and what he'll be like come the 4th and 5th inning... It's like a self-fulfilling prophecy...
