Discussion: Is Superman injured?

I noticed that Superman has not been doing so well this winter. Mark Voit was ahead of him for a while on Dec 16 at Great Falls, but the big guy surged at the end. Then Graeme just blew him away at White Clay Creek on Mar 10. And a few days later in Calgary some Canadian put the hurt on him. He must have been tired from flying up there just 3 days after the humiliating defeat in Delaware. Maybe he mistakenly bought the Moscow 3K compass. It seems any reasonably fast runner who skips a split can kick Superman's ass.
