when did the ground rule double go into effect
Ground rule double In the early years of baseball, all batted balls that cleared the fence after a bounce in fair territory or on a fly were counted as home runs. The rule was changed by the American League prior to the 1930 season and subsequently by the National League on December 12, 1930. Notably, the pre-1930 rule includes most of Babe Ruth's career. Early baseball statistics do not differentiate between home runs that cleared the fence on a bounce compared to those that did not. However, most baseball historians believe that Ruth likely missed out on more home runs that did not count due to other differences in the rules in place during his career compared to the number of home runs he likely hit off bounces.[citation needed]
Double (basketball) A quadruple-double is defined as a performance in which a player accumulates a double digit number total in four of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game.[81] This feat is extremely rare:[81][82] only four players have officially recorded a quadruple-double in National Basketball Association (NBA) history. The first American male player above the high school level to officially record a quadruple-double was Nate Thurmond, who achieved this feat in 1974 while playing for the NBA's Chicago Bulls. The first American female player above the high school level to officially record a quadruple-double was Ann Meyers, who achieved this feat in 1978 while playing for the UCLA Bruins, when women's college sports were under the auspices of the AIAW.[83] The first male player in NCAA Division I history to record a quadruple-double was Lester Hudson in 2007.[84] The first Division I women's player to have officially recorded a quadruple-double since the NCAA began sponsoring women's sports in 1981–82 was Veronica Pettry of Loyola of Chicago in 1989; only two other women have done so since, and none since 1993. An earlier player, Jackie Spencer of Louisville, accomplished the feat against Cincinnati during the 1984–85 season, but the NCAA did not record assists and steals throughout Division I women's basketball at that time. The Metro Conference, then home to both schools, did officially record these statistics, but the NCAA did not start doing so until 1985–86 for assists and 1987–88 for steals.[69]
