In recent years it has become relatively commonplace for a team's PR staff to put out game notes that list a bunch of TBDs as the pitching probables. Managers are becoming more and more hesitant to give away even seemingly innocuous information, and the surge of openers has made it even more difficult to predict what a series might look like.
This season, you can expect even more of this, but for a whole new reason. With just three weeks to prepare for a 60-game season, teams do not expect to have true five-man rotations. Gabe Kapler made it clear earlier this week that his starting staff will carry a much different type of workload, but there still will be a starting staff in some form.
