when did major league baseball players quit leaving their gloves in the field between innings?
595939
Players used to leave their gloves on the field when their team came up to bat. This stopped by 1954, when a rule prohibiting the offensive team from leaving gloves and other equipment on the field went into effect.

Walk-off home run\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\nIn baseball, a walk-off home run is a home run which ends the game. It must be a home run that gives the home team the lead in the bottom of the 9th inning or the bottom of any extra inning. It is called a "walk-off" home run because the teams walk off the field immediately afterward. Sportscasters also use the term "walk-off double" or other such terms if such a hit drives in the winning run to end the game. The terms walk-off hit by pitch or walk-off balk have been applied, and the latter has been dubbed a balk-off (these types of questionable walk-offs are seen by some fans as cheapening the concept). Although the concept is as old as baseball, the term itself has come into use only in the last few decades

Vida Blue of Oakland was the youngest in the modern era.  He was 21 years, 1 month when he no-hit the Twins in 1970.  Bud Smith, who someone else mentioned here, was the fourth youngest at 21 years, 11 months.\n\nAmos Rusie was the youngest in Major League history.  The modern era is anything after 1900.  He was 20 years, 2 months when he pitched a no-hitter for the New York Giants in 1890 against the Brooklyn Dodgers.\n\nMatt Cain of the Giants almost beat Blue's record last week when he took a no-hitter into the eighth inning against the Angels.  He's also 21, but I don't know how many months.\n\nAnother bit of trivia is that Rusie, "The Hoosier Thunderbolt" is the reason the pitcher's mound is 60 feet-6 inches from home plate.  When his career started, it was 50 feet from the plate. He was so dominant, they moved it back.\n\nA.J. Burnett was 24 years, 5 months when he pitched his no-hitter.  He is in the record book, though, as the only guy to walk nine batters in a no-hitter.\n\nNolan Ryan threw the most no-hitters with seven.  He also has the distinction of being the youngest player in the league his rookie year at the age of 19 and the oldest player in the league the last eight years running of his career, which ended at the age of 46 years, 1 month. But he was 26 years, 4 months when he pitched his first no-hitter in 1973.  He pitched two that year.

Baseball's modern era began in 1900 but was played for several years before that.  There were probably no records kept back then.

I didn't know that there was any time that MLB forced fans to run on the field in the postseason. Sounds strange to me.

Ernie Shore. On June 23, 1917, Ruth walked Ray Morgan, the first Washington batter, and then was ejected after protesting the call and assaulting umpire Brick Owens. (Ruth had to be led off the field by a policeman.) Ernie Shore relieved and after Morgan was thrown out stealing, Shore retired the next 26 batters and made Ruth a footnote to an all-but-perfect game.

September 10, 1960: In Detroit, Mickey Mantle unloads a cannon shot for three runs in the 6th inning, the ball clearing the RF roof and landing in the Brooks Lumber Yard across Trumbull Avenue. New York pins a 5–1 loss on Paul Foytack that moves them a half game in first place ahead of Baltimore, losers today. In June, 1985, Mantle's blow was retroactively measured at 643 feet, and will be listed in The Guinness Book of World Records at that distance

A "walk-off" home run is a home run hit by the home team in the bottom of the ninth inning or later to seal the win when before the score was a tie or the home team was trailing. Two World Series, out of 102, have ended in a walk-off home run. They are the 1960 Pirates vs. Yankees matchup, which the Pirates won in Game 7 on slick-fielding Hall of Fame second baseman Bill Mazeroski's walk-off solo home run on a pitch by Ralph Terry, and the 1993 Blue Jays vs. Phillies classic, with Joe Carter of the Blue Jays crushing a dramatic home run off closer Mitch 'Wild Thing' Williams. The term was coined by Hall of Fame reliever Dennis Eckersley. The term has come to mean the batter walks off the field after hitting the home run, or the long walk to the dugout by the losing pitcher. There are "walk-off" base hits, but as they are not home runs, they are not spoken as "walk-off" hits that often. More often, they are game-winning hits.

According to the Baseball Hall of Fame and assuming you meant any game in general, rather than only MLB, the longest game was  33 innings.\n\nSome interesting tidbits from the longest game in professional baseball history - a 33-inning marathon between the Rochester Red Wings and Pawtucket Red Sox that began on April 18, 1981 and concluded nearly two months later: \n\nExtra special: The game surpassed by four innings the previous longevity record, established by Miami and St. Petersburg of the Florida State League in 1966. \n\nTime of game: 8 hours, 25 minutes. Achy, breaky knees: Wings catcher Dave Huppert caught 31 innings. \n\nSee the link below for full details.

Johnny Vander Meer of the Cincinnati Reds did it in 1938.  On June 11 he no-hit the Boston Braves, 3-0, and on June 15 he no-hit the Brooklyn Dodgers, 6-0.  Both games were away games; the second no-hitter was the first night game ever played at Ebbets Field.
