Just going by those stats, Armstrong seems worth a flyer to me. He's pretty much better statistically than Wright across the board, although I know we are comparing relievers with starters here. The high K rate and reasonably low HR rate, even in the PCL, are pretty encouraging. Control looks like a potential issue. Hopefully he's healthy.
