I have to say I was more than a little surprised when I saw that Brett Marshall was the 40-man roster casualty for Carlos Beltran yesterday. He wasn't very good in Triple-A last year as a starter or in his handful of Major League relief appearances, but he's still just 23 years old with a good fastball and a plus changeup. That seems like a commodity much more worthy of being held onto than a washed up 35-year-old outfielder who can't hit anymore. But in looking at the projected starting rotations for the Yankees and the SWB RailRiders, it starts to make a little more sense.
Yankee Rotation: CC Sabathia, Hiroki Kuroda, Ivan Nova, Free Agent Pitcher X, Winner of the Pineda/Phelps/Warren/Nuno ST competition (probably Pineda or Phelps)
RailRider Rotation: Manny Banuelos, Vidal Nuno, Jose Ramirez, Nik Turley, Shane Greene
With guys below him in Double-A having better years and moving up and ManBan being healthy again, Marshall's Triple-A rotation spot wasn't the sure thing it was last year. And with Phelps and Warren already more established as Major League swingmen, Marshall wasn't going to beat them out for a spot on the 25-man roster. His poor 2013 made him expendable and the Yankees probably felt they had enough MiL depth in Triple-A to cover for injuries.
It sucks for him and hopefully Marshall clears waivers and stays in the organization, because I do think he can develop into a decent pitcher, but that's life for a low-ceiling prospect on a team with constant 40-man roster issues.
