Baseball Scorecard Basics: Follow an Inning
A scorecard turns a game into a quick visual record: who batted, how the play ended, where runners went, and how many runs crossed the plate. You don’t need a complicated notation system to get started.

Start with the fielding numbers
Scorekeepers use numbers for defensive positions. Learn this sequence and a play such as “6–3” becomes readable: 1 pitcher, 2 catcher, 3 first baseman, 4 second baseman, 5 third baseman, 6 shortstop, 7 left fielder, 8 center fielder and 9 right fielder.
For a groundout from shortstop to first, write “6–3” in the batter’s box: the shortstop fielded the ball and the first baseman completed the out. A fly ball caught by the center fielder can be marked “8.” MLB notes that fans use different scorecard methods; these numbers are a practical common language, while some symbols vary.
Give each batter a box
Most paper scorecards provide a small box for each batter in each inning, plus a diamond to track the bases. Put the result in the batter’s box and mark the runner’s progress around the diamond. You can use simple labels:
- 1B, 2B, 3B, HR: single, double, triple or home run.
- BB: walk. The batter is awarded first base; MLB’s scorekeeping reference uses BB.
- K: strikeout.
- E: error, if the official scorer rules the play that way.
- 6–3, 4–3, etc.: record the defensive sequence on a putout. The first number is the fielder who handled the ball; the last is the player who completed the out.
These are convenient annotations, not a requirement to use one exact personal system. The aim is to remember what happened and where the runners ended up.
Track outs and runners as the inning moves
After each play, update the number of outs and move any runners to the bases they reached. If a runner scores, mark that run on the diamond and in the inning’s run total. At three outs, the batting side’s half-inning ends; the other team bats next. In the bottom of the final inning, the home team may not need to bat if it already leads.
Simple example: A batter walks, then the next batter hits a home run. Mark BB and the runner at first; on the homer, trace both runners around the diamond and mark two runs for that half-inning. Repeat the same process for each batter rather than trying to reconstruct the inning later.
Read the line score
The familiar line score lists each team’s runs by inning, then gives totals for R (runs), H (hits) and E (errors). At the end of each inning, add that inning’s runs and hits to the team totals. An error is a scorer’s judgment, so a fan’s note of a difficult play may not match the official record.
A player line can also show AB (at-bats), R, H, RBI, BB and SO (strikeouts). At-bats are not the same as plate appearances: walks, for example, do not count as official at-bats. Reading those columns alongside the inning-by-inning card tells you both the team story and each hitter’s day.
