If the Orioles don't sign another starting pitcher, left-hander Zach Britton is the likely favorite to win the fifth spot in the rotation because he's out of options, according to Roch Kubatko of MASNsports.com.
If needed, the Orioles could send starting pitcher candidates Kevin Gausman, Steve Johnson and T.J. McFarland to the minors and bring them up later in the season. Though, McFarland could be a candidate for the bullpen while Troy Patton serves a 25-game suspension at the outset of the season.
However, Kubatko expects the Orioles will sign another starter. Chris Tillman, Wei-Yin Chen, Miguel Gonzalez and Bud Norris are expected to fill the first four spots in the team's rotation.
