Taking a guess at the minor league rotations

The Orioles have not yet announced their pitching rotations for three of their four full-season minor league clubs. But at this point, it's worth taking an educated guess at what we might see on the mound starting next Thursday. A few days ago, O's skipper Dave Trembley told reporters that Chris Tillman, Jake Arrieta, Brandon Erbe, Troy Patton and Alfredo Simon would begin the year in the Norfolk Triple-A rotation. The order of the rotation has not been announced. Here are some guesses at the other rotations: Double-A Bowie: Zach Britton, Steve Johnson and Chorye Spoone appear pretty set for that starting five. Others that could join them include Tim Bascom, Ryohei Tanaka and Pat Egan. At Frederick, it looks like six candidates are vying for rotation spots. They are Rick Zagone, Cole McCurry, Kenny Moreland, Oliver Drake, Nate Nery and Ryan O'Shea. At Delmarva, Matt Hobgood, last June's top draft pick, is expected to make that rotation. He could be joined by Jesse Beal, Ryan Berry, Vito Frabizio and Jake Cowan. Others expected to make the Delmarva staff include Bobby Bundy, Tony Butler and Randy Henry. Keep in mind these are my own guesses at this point and nothing beyond the Triple-A rotation has been confirmed by the club yet. Meanwhile, hope you can join me on opening night at the ESPNZone.
