TAMPA — Ahead of the first official workout of the spring for pitchers and catchers on Thursday, the Yankees held a team meeting inside the clubhouse at George M. Steinbrenner Field.

The main topic? Rules, and more specifically, clocks.

Three rule changes are coming to MLB this season: pitch timers, shift restrictions and bigger bases. They will loom over camp this spring, especially once Grapefruit League games begin, as teams try to get their players adjusted to hit the ground running by Opening Day.

On Thursday, the Yankees’ presentation — led by coaching assistant/advance scouting director Brett Weber — was geared toward the pitch timers that are aimed at speeding up the pace of play. Then they put it into motion during their afternoon workouts.
