It Was a Very Good Year

Mark Eichhorn is the holdest of what single season feat for relief pitchers (guys with zero starts)??

Anything to do with ERA like "lowest ERA by a pitcher with more than 150 innings and zero starts".

This is correct, though I had a different wording of the answer (but they are basically the same thing). The answer I had work up was "most innings pitched by a pitcher with zero starts and a sub 2.00 ERA".

Good job, UC.
