Gray (foot) will throw a simulated game Tuesday, MLB Network Radio reports.
After completing a 41-pitch bullpen session Saturday, Gray is ready to face hitters, and appears on the verge of heading out on a rehab assignment. His arm is fine, it's just a matter of making sure he is fully recovered from a stress fracture in his left foot that has sidelined him for almost two months. Gray has as much strikeout upside as any pitcher who is not widely considered an SP1, it is just a matter of him limiting baserunners and navigating his home starts in the unfriendly confines at Coors Field.
