Atlantic League to move mound back foot as MLB experiment

The Atlantic League, a minor league hotbed for innovation in baseball, will announce plans Wednesday to move the pitcher’s mound back 12 inches from home plate this season, according to two people with knowledge of the arrangement. The move represents one of the most stark rule changes proposed by baseball leadership in a generation and comes amid sweeping changes on the minor league level designed to reduce home runs and strikeouts and increase the action from batter to batter.

The eight-team Atlantic League, which has franchises along the East Coast, will enact the change during the second half of its 120-game regular season, one person familiar with the matter said. It will be the first change of mound regulations in professional baseball since 1969, when MLB lowered the mound after a season in which seven starting pitchers posted sub-2.00 ERAs.

MLB officials pushed for the experiment after years of internal deliberations about altering the distance from the mound to home plate, one of the people familiar with the discussions, who spoke anonymously so as to freely detail the private sessions, told The Washington Post. It is geared toward increasing action on the base paths and cutting down on strikeouts and home runs.

“[MLB leaders] reached the conclusion that the things that drew us to the game in the first place are being eclipsed by absolute outcomes, and, frankly, people find it boring,” one of the people involved in the decision said. “Batters will hit the ball more frequently, and that’s really the root of what we’re doing here.”

An MLB official, speaking on condition of anonymity to discuss internal deliberations, explained that moving back the mound back has been brought up for years, but then dismissed as too radical.

But when the league began to consider other, more minor changes, its leadership concluded it would be “negligent” not to test the one change that might solve the problem on its own.

“We kept coming back to the fact that we can try to change four or five things, and we’re going to, to try to nudge the game in the right direction and get more contact back,” an MLB official said. “But we’d probably be negligent if we didn’t at least try the one solution that, while we were calling it radical, might in and of itself be the solution.”

The Atlantic League will also institute a “double hook” rule governing the designated hitter: Teams can keep a DH in their lineups as long as their starting pitcher remains in the game. When a manager goes to the bullpen, the new pitcher must bat or be substituted out of the game.

That rule amounts to a compromise between the rules in the American League, where teams can use the designated hitter for all of their pitchers, and the National League, where teams are not allowed to use one at all.

MLB hopes that allowing teams to use a designated hitter until the starter is out of the game will incentivize teams to rely more on starting pitchers, something the league’s fan surveys said would be a popular shift. At a time when several teams use “openers” for a few innings and even proven top starters often last just five or six innings, league officials hoped the loss of a designated hitter might influence some managers to keep their starter in an inning or two more.

Both leagues used the designated hitter in the shortened 2020 season as part of MLB’s health and safety protocols. When MLB and the players’ union discussed covid-19 protocols ahead of the 2021 season, the union proposed a universal designated hitter again. MLB did not agree, though many in the industry expect a universal designated hitter to be part of the next collective bargaining agreement.

Moving the mound back has not been expected to be part of those conversations, and it almost certainly will be a polarizing experiment. The Atlantic League tried to push the mound back two feet in 2019, before its agreement with MLB, but withdrew the proposal after pushback from pitchers, several of whom threatened to leave the league.

The Atlantic League is independent and its teams are not affiliated with MLB franchises. It is a partner league with MLB and has debuted experiential rules before - perhaps most notably so-called “robo umps.” Players there are signed by the teams themselves, which means they are not usually elite prospects and are never under contract with major league organizations.

But even though it won’t be tested on highly paid young players, the new rule could reignite tensions over MLB Commissioner Rob Manfred’s newly experimental eye toward the game. Earlier this year, Manfred hired Theo Epstein, the former president of baseball operations for the Chicago Cubs and the former general manager of the Boston Red Sox, to serve as a consultant tasked with finding new ways to increase in-game action and pace of play.

Since Epstein joined the commissioner’s office in January, MLB has announced several experimental rule changes at the minor league levels, including larger bases and rules limiting defensive shifts. Many of those rules have Atlantic League origins and now have a clear path to the big leagues: Class AA teams may no longer shift their infielders as dramatically, and Class AAA teams will play with bases that are 18 inches square. Major league pitchers also must face a minimum of three batters before being pulled from the game, another Atlantic League innovation.

“These rule changes are extremely viable - otherwise MLB wouldn’t do them,” one of the people involved in the discussions said.
