Dobnak started on short rest a couple weeks ago! (Due to a doubleheader.) But yeah, in modern MLB, virtually no one uses starters on short rest outside elimination games, so I don't think Rocco's record up to this point means much in this regard. And I too don't think he'd start someone on short rest if he had a good alternative -- for example, I don't think he'd use Maeda on short rest if one of Berrios, Pineda, or Hill was available on full rest. But right now, there seems be a pretty bright line after our top 4 starters, pending what Odorizzi, Bailey, and/or Dobnak might show before then.
