While most seem to embrace the idea, they acknowledge it's uncharted territory and yet another strategic tool to employ during games.

The issue was a consistent line of questioning when managers and general managers of the 15 teams that hold spring training in Arizona gathered for MLB media day on Tuesday.

All clubs will get a chance to test the new system in a handful of spring training games, although details of that schedule had not been determined.

Each team will get at least a minimum number of games this spring to test the rule. Teams with more spring training games that are televised probably will have more opportunities to try out the new system.
