Double-double

In basketball, a double-double is a single-game performance in which a player accumulates ten or more in two of the following five statistical categories: points, rebounds, assists, steals, and blocked shots. The first "double" in the term refers to the two (double) categories and the second "double" refers to accumulating ten or more (typically double digits) in that category. Similarly, a player records a triple-double, quadruple-double, and quintuple-double when accumulating ten or more in three, four, or all five of the statistical categories, respectively. While double-doubles and triple-doubles occur regularly each NBA season, only four quadruple-doubles have ever been officially recorded in the league. Those performances were recorded by Nate Thurmond (1974), Alvin Robertson (1986), Hakeem Olajuwon (1990), and David Robinson (1994). It is sometimes claimed that Wilt Chamberlain recorded an unofficial quintuple-double on March 18, 1968, in a 158–128 Philadelphia 76ers win over the Los Angeles Lakers with the official box score showing 53 points, 32 rebounds, and 14 assists, and later reconstructions attributing additional blocks and steals. Because the NBA did not begin officially recording steals and blocks until the 1973–74 season, such claims are not recognized as official league records. A related achievement, the five-by-five, is recorded when a player totals at least five each in points, rebounds, assists, steals, and blocks in a single game; it is also rare.
