Joe Saunders signed a one-year pact with the Seattle Mariners late last week. With Saunders off the market, it appears likely that the Orioles will look internally for a 5th starter to join Jason Hammel, Wei-Yin Chen, Miguel Gonzalez, and Chris Tillman in starting rotation. The list of potential candidates includes: Zach Britton (L), Jake Arrieta (R), Steve Johnson (R), Brian Matusz (L), T.J. McFarland (L), and if his contract indeed becomes finalized, Jair Jurrjens (R). Zach Britton is my pre-Spring Training favorite for the final rotation spot in Baltimore. I have some thoughts on him that I’ll try to share at a later date, but I want to talk about a more under-the-radar candidate, Rule V draft pick T.J. McFarland.
