Zimmermann left after 2 complete innings. The plan was for Stallings to piggy-back off Zimmerman's start. I believe the plan was for Bruce to go 3 innings but he threw 41 pitches (24 strikes) in 2 innings.
If I am correct, the collective bargaining agreement says no more that 20 games in a row. The players agreed to the schedule and while it sicks, it is what it is.
