Of course he's been overworked. But the most important thing is to get Hoover back on track. Pitching to two hitters tonight, had it worked, would have helped.
I just don't think this guy's problem is overwork. I think his pitches are too good, they get too much of the plate. I don't think he quite has the stuff to get away with it.
But, yes, Hoover has been overused.
