[i] This list omits Denny Lyons of the 1887 American Association Philadelphia Athletics, who had a 52-game hitting streak.
In 1968, MLB ruled that walks in 1887 would not be counted as hits, so Lyons' streak was no longer recognized, though it still appears on some lists.
In 2000, Major League Baseball reversed its 1968 decision, ruling that the statistics which were recognized in each year's official records should stand, even in cases where they were later proven incorrect.
Paradoxically, the ruling affects only hit totals for the year; the batting champion for the year is not recognized as the all-time leader despite having the highest single-season average under the ruling, and Lyons' hitting streak is not recognized.
Excluded on this list are Henry Larkin, who accomplished this with the Washington Senators in the American Association, and Ed Delahanty, with the Philadelphia Phillies in the Players' League.
