Key word there is "compete". Obviously Woodruff, Burnes and Peralta are assured spots, and I have to imagine Lauer is a lock as well. Doubt Miley is going to be pitching out of the pen, so he's probably a lock as well. If they go with a 6-man rotation, which seems likely at this point, that leaves Ashby, Houser and Wilson in competition for that role, with the two losers likely going to the pen. Not such a bad problem to have.
