pitch, his first hit batsman of the series). Other overall game information is shown at the bottom of the box score. U – umpire crew (Six umpires worked this game, listed by umpiring position. The home plate umpire is listed first, then the umpires for each base in order, then the left and right field umpires, if any. In inter-league play, league affiliations were also shown, but, with the merger of the major-league umpiring staffs prior to the 2000 season, these references have been eliminated .) T – time of the game, not counting rain delays or light failure (The game was played in three hours and forty-six minutes.) A – paid attendance (55,155 tickets were sold for this game.) Most box scores also give the temperature, weather, and wind speed/direction. Other events not shown in the example but recorded in most box scores include sacrifice hits ("S"), triple plays ("TP"), balks ("BK"), blown saves ("BS"), and passed balls ("PB"). Many box scores, to save space, do not list any categories where none of that event occurred in the game. Others will list the category followed by " – None". In a baseball game, the number of plate appearances for each team must be equal to the number of batters put out, scored, and left on base. A box score is in balance (or proved) when the total of the team's times at bat, bases on balls received, hit batters, sacrifice bunts, sacrifice flies and batters awarded first base because of interference or obstruction equals the total of that team's runs, players left on base and the opposing team's putouts. In other words, the box score is accounting for the number of batters and what became of them (scored, left on base, or put out). If a box score is unbalanced, then there is a logical contradiction and thus an error somewhere in the box score. Early box scores The first box scores tended to be vaguely related to cricket scorekeeping, in that only two offense-oriented figures were presented for each batter: "O" and "R", meaning "number of times put out" and "number of runs scored", respectively. As fan interest in all aspects of the game increased, the box scores were revised and expanded to include the offensive categories At-Bats, Runs, Hits and sometimes Total Bases; and the defensive categories Put-Outs, Assists and Errors for each batter, as well as
