The rule stated that batters may “steal” first base on any pitch not caught in flight and the batter may be thrown out if he tries to run
Other rule debuts in the independent league included the use of electronic strike zones, which have been labeled "robot umpires." In the Atlantic League All-Star game this past Wednesday, the home plate umpire had an earpiece hooked up to an iPhone that tracked balls and strikes using radar.
Other changes include moving the pitcher's mound back to increase offensive production and allowing a player one foul bunt on two strikes before he's called out. In MLB, if a player bunts the ball foul on two strikes, he is automatically ruled out
