Regular season leaders There have been 57 occurrences in
Major League Baseball where a player had a hitting streak of at least 30 games. Multiple streaks in the same season have occurred in 1922 (
George Sisler and
Rogers Hornsby), 1987 (
Paul Molitor and
Benito Santiago), 1997 (
Nomar Garciaparra and
Sandy Alomar Jr.), 1999 (
Vladimir Guerrero and
Luis Gonzalez), 2006 (
Chase Utley and
Willy Taveras), and 2011 (
Andre Ethier and
Dan Uggla). In addition, 1924 included one whole streak (
Sam Rice) and the beginning of another (
George Sisler). A similar event occurred in 2006 with two whole streaks (
Utley and
Taveras) and the end of another (
Jimmy Rollins). Keeler's streak started in his final game of the 1896 season, and continued through the first 44 games of the 1897 season. Rollins ended the 2005 season with a 36-game streak and extended it through the first two games of the 2006 season. Sisler had a hit in the last game of 1924 and the first 34 games of 1925. Major League Baseball recognizes two hitting streak records: Longest hitting streak in one season, and longest hitting streak over multiple seasons (e.g. Rollins 2005–2006). Keeler's, Sisler's, and Rollins' streaks are listed as 44, 34, and 36 games when discussing
single-season streaks, and 45, 35, and 38 games when discussing
multiple-season streaks. This list omits
Denny Lyons of the 1887
American Association Philadelphia Athletics, who had a 52-game hitting streak. In
1887, the major leagues adopted a new rule which counted
walks as hits, a rule which was dropped after that season. Lyons hit in 52 consecutive games that season, but his streak included two games (#22 and #44) in which his only "hits" were walks. 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. Ty Cobb, Sam Rice, and George Sisler are the only players with multiple streaks of 30 games or longer. There have been 129 single-season streaks of 25 games or more. The lowest
batting average ever recorded during a hitting streak of 25 games or more was .304 by
Bruce Campbell in
1938. The highest was .486 during
Chuck Klein's streak in
1930. Joe DiMaggio hit .408 during his record-holding 56-game streak. In probability theory, every baseball game is a
Bernoulli trial in which a hitter either does or does not get a hit. DiMaggio's streak of 56 consecutive games with hits awaits an equal streak: "The probability is .0003 that a .350 hitter will have a hitting streak of at least 56 games in a season. If there are about four such seasons per year in the future, such a streak would be expected, assuming the Bernoulli trials model, every 1/(.0003 x 4) = 833 years."
Postseason leaders Key Source: Major League Baseball records by franchise Only currently extant franchises are included on this list. Where a player had a significant streak while the team was in other than its current city, the records in these other cities are displayed. As above, for a multi-year streak, the single-season streak is shown in parentheses. ==Minor League Baseball leaders==
