Major League Baseball plans to experiment with more potential radical changes to the game.

The league is using its new partnership with the independent Atlantic League to try out new rules this season, which include robot umpires, extending the pitcher's mound to 62-feet, 6-inches and no infield shifting.

MLB has tested rule changes in the past with minor-league baseball but has a new three-year partnership with the Atlantic League.

The full list of Atlantic League changes announced on Friday are:

-Using TrackMan radar system to assist umpires in calling balls and strikes
-Moving the pitcher's mound back from 60 feet, six inches, to 62 feet, six inches.
-Requiring two infielders on each side of second base when a pitch is released. The pitcher will be penalized with a ball if the rule is violated.
-A three-batter minimum for pitchers.
-No mound visits aside from pitching changes or injuries.
-Increasing the size of first, second and third base from 15 inches to 18 inches.
-Reducing the time between innings and pitching changes from two minutes and five seconds to one minute and 45 seconds.

"This first group of experimental changes is designed to create more balls in play, defensive action, baserunning, and improve player safety," Morgan Sword, MLB senior vice president, league economics and operations, said in a statement. "We look forward to seeing them in action in the Atlantic League."
