In [[Major League Baseball]], instant replay has been introduced to address "boundary calls," which including questions on whether a hit should be considered a home run (HR). Among reviewable plays are Fair Ball-HR, Foul Ball, Ball Clearing Wall-HR, Ball Staying in Play-Live Ball, Ball Leaving Field of Play-HR, and Ball or Player interfered with by spectators (called [[Interference (baseball)|Spectator Interference]]). The latest MLB collective bargaining agreement expands instant replay to include Fair Ball Foul Ball along foul lines or Ball Caught for Out Ball Trapped Against Ground or Wall. It expands interference calls to all walls regardless of whether they are "boundary calls" or not.

In Little League Baseball, instant replay was initially adopted for the Little League World Series only but later expanded to include the qualifying regional tournaments. It consists of all "boundary call" plays reviewable at the Major League Level and adding review to plays involving force outs, tag plays on the base paths, hit batters, and defensive appeals regarding whether a runner missed touching a base.<ref>{{cite web | url=https://www.latimes.com/archives/la-xpm-2010-aug-02-la-sp-0803-little-league-20100803-story.html |title=Little League to expand instant replay|date=August 2, 2010|work=[[Los Angeles Times]] |last=Baxter |first=Kevin |access-date=May 24, 2011}}</ref>
