Scoring a game
From BR Bullpen
Scoring a game is the act of following a baseball game hitter by hitter, pitch by pitch, with the outcome of each hitter reflected by line markings.
Score is kept on a special sheet of paper called a scorecard or scoresheet, marked with a grid, with columns delinating the inning and rows corresponding to slots in the batting order. Each position is denoted by a number. They are as follows:
- Pitcher 1
- Catcher 2
- First Baseman 3
- Second Baseman 4
- Third Baseman 5
- Shortstop 6
- Left Fielder 7
- Center Fielder 8
- Right Fielder 9
Furthermore, each play has a code, which varies from one scorer to another. A fly ball out can be marked with a circle and the fielder's number inside the circle, or by the letter "F" followed by the fielder's number; in this system, a line-out can be scored "L" followed by the number, and a foul ball caught on the fly can be designated by a lower-case "f" or "l" followed by the number. A ground ball out is delineated by a hyphen, such as a ground ball out from shortstop to first base is 6-3 and read as "six to three". Double plays are written as "DP 6-4-3", such that the shortstop threw to the second baseman who threw it to the first baseman to complete the play. If the out is the result of a sacrifice, the notation "Sac" is usually added before the out (i.e. "Sac 2-3", or "Sac F9"). A player reaching on an error would be marked "E" followed by the position number of the player who committed the error, next to the base which he reached.
Hits are marked on an outline of the baseball diamond on the specially printed sheet. Each advance of a base is denoted by continuing the line around the diamond. A triple would be outlined to third base and 3B would be written in the box. Should the runner score, the scorer would continue the line to home plate, then color in the diamond. An alternate way to score hits, if there is no diamond outline, would be to mark a single horizontal stroke in the lower right hand corner to denote singles (with BB in this same area for walks, HP for hit by pitch, etc.); two horizontal strokes in the upper right hand corner for doubles; three horizontal strokes in the upper left hand corner for triples; and four horizontal strokes in the lower left hand corner for home runs. A run scored would be denoted by a circle in the center of the box (colored-in for earned runs, not colored in for unearned runs).
The scorer can also mark events that occured on the basepath. For example, if the batter gets a single, the scorer would write single but if the runner steals second, the scorer would make a line to second and write "SB" above the line. If the advancement is the result of a wild pitch, passed ball or balk, the notations "WP", "PB" and BK" are used. Similarly, if the batter advances to second on a hit or out by a teammate, the scorer would make a line to second, and write the position number of the player who advanced the batter. For example, if the batter advanced to second when his or her teammate, the left fielder, hit a sacrifice, the scorer would simply write the number 7 above the line to indicate an advance to second on the play by the left fielder.
For pitching, some scorecards may have circles to bubble in the count. If a batter strikes out, the scorer would write a K inside the diamond given. If the batter strikes out looking, the scorer would put a backwards K or Kc in the diamond given. Another method of recording strikeouts is K if the batter strikes out looking and K2 if he strikes out swinging.
Walks are denoted by a "BB".
A batting player receives an RBI (run batted in) when the result of his at bat scores a runner on any of the bases. However, there are exceptions to this rule, including when the batter reaches base on an error. An RBI can be marked by a star or an asterisk next to the result of the at bat (for example 4-3* would be a ground out, second base to first base, which drives in a run).
An earned run is attributed to the pitcher when a batter that pitcher faced scores without an error or passed ball occuring, or if the run would have scored even if there had been no error.
 Historical Note
The numbering of positions as we know them was only fixed in the first years of the 20th Century. Before that time, there were competing numbering systems, some of which would assign number 5 to the shortstop and number 6 to the third baseman (a more logical assignment, when one thinks about it), or would number the outfield positions from right to left. Indeed, the man generally credited with inventing the concept of the scorecard, Henry Chadwick, was of the opinion that fielders be numbered according to their position in the batting order. For example, "F1" was a fly ball caught by whoever batted first in the opposing batting order. In an era when there were almost no substitutions, but players changed positions from game-to-game, this would have made a certain sense. Such a system would however be massively confusing today.
Phil Rizzuto introduced the code "WW". When asked why he had WW in his scorebook, Rizzuto said he "Wasn't Watching".
