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. Those will be granted on the request of the catcher on a case-by-case basis.

Limiting the number of mound visits to six was a compromise from the league office to the players union, which opposed MLB’s plan to establish a pitch clock that included game-altering penalties.

How many visits each team has remaining will be shown on the stadium scoreboard as an additional column on the line score.

Seeing MVR after LOB for runners left on base will take some getting used to, but knowing how many visits a team has over the course of the game will be as clear as day.

As the Orioles and Minnesota Twins worked out at Camden Yards on Wednesday afternoon, tests of the stadium scoreboard showed the MVR column.

And, no, that’s not the Orioles’ Opening Day starting lineup.

But now, when your confused friend looks up at the scoreboard and asks what MVR is, you’ll be the smart one.
