Major League Baseball is widening the runner's lane approaching first base to include a portion of fair territory, changing a more than century-old rule that caused World Series controversy over interference calls. MLB also is shortening the pitch clock with runners on base by two seconds to 18 and further reducing mound visits in an effort to speed games. The new runner's lane overrides a rule that has existed since the National League mandated in 1882 that runners must be within the 3-foot box on the foul side of the base line during the final 45 feet between home and first.
