Miz is different man. The number of pitching prospects we've had in our team's history that are as special as him can be counted on one hand. We are not risking his arm to save Jared Koenig's, respectfully.
If we are that worried about the bullpen then start Tobias tomorrow and follow him up with Carlos and tell those two they get all nine innings regardless of what happens.
Patrick? Sure. Hall? Sure. Myers? Sure. Use them. Ask for more.
Keep Miz on whatever program you have installed for him with reasonable adjustments given this season's circumstances.
If Miz gets hurt from overuse this season and it affects his future,.. it will be an unforgivable malpractice from this front office.
