On Opening Day, know your MVR

Get ready for another initialism to enter the baseball vernacular beginning Thursday on Opening Day: MVR or “Mound Visits Remaining.”

Major League Baseball’s latest round of pace-of-play rules, which go into effect this season, include a limit to the number of mound visits a manager, pitching coach or teammate can make over a nine-inning game.

Each team will get six mound visits over the course of a nine-inning game — not counting visits that include a pitching change — and each team will receive an additional visit for each extra inning.

Umpires can award additional visits by the catcher if his signals with the pitcher get crossed up.
