EDGE Analysis

This setback will bring Minor's rehab assignment to an abrupt halt, but manager Ned Yost was adamant that it's nothing serious. The training staff will give Minor a look over this week to determine when he may be able to resume his rehab. Minor went six innings for Triple-A Omaha on Monday, allowing four runs on seven hits and one walk while striking out four (83 pitches).
