Prized Marlins righty Sixto Sanchez cut his most recent throwing session short due to what the Marlins termed “slight discomfort” in his right shoulder, tweets Jordan McPherson of the Miami Herald. He’ll be evaluated over the coming days as the Marlins determine a course of action.

MLB.com’s Christina De Nicola adds that Sanchez had been slated to throw around five “innings” and 75 pitches in a simulated game but cut things short after just the second frame, at which point he informed the team of the discomfort.
