A baseball inning is divided into two turns at bat. The visiting team bats in the top half; the home team bats in the bottom half. The inning number therefore needs its top-or-bottom marker to tell you where the game stands. A fourth-inning score with two outs in the top is a different situation from the same score late in the bottom.

Use the arrow with the inning number
Broadcasters commonly place a small upward or downward marker near the inning number. Its design varies, so use the team currently batting to confirm the meaning. When the third out ends a half-inning, the fielders leave and the other team takes its turn. The scoreboard may display a break while the pitcher warms up. That is a normal transition, not a fresh game or an unexplained disappearance of the previous runners.
Read a line score across the row
A line score records runs by inning for each team. A blank or unfinished cell can mean the relevant half-inning has not been completed, rather than a scoring error. Read the team row and inning column together. The total-runs column summarizes the game score, while hits and errors occupy separate columns. A team can have more hits but fewer runs because reaching base and completing a scoring trip are different achievements. The line score explains when scoring happened without recreating every plate appearance.
Understand why the final bottom half may be absent
The home team's final turn is unnecessary when it is already ahead after the visitor's last required half-inning. That is why a completed game can show fewer home batting turns than visiting batting turns. If the home team takes the lead during its final opportunity, a walk-off ending can stop the contest before three outs, subject to the rules for the play. Do not expect the broadcast to manufacture an unused batting turn just to make the line score symmetrical.
Follow one inning as two connected tests
Watch the top half and ask what the visiting offense creates. Then watch the bottom and see how the home offense responds. The fielding and pitching jobs switch, but the game score carries forward. For a useful exercise, note the score at the start, middle and end of an inning, along with runners left on base. This reveals why a clean defensive half can matter even without an immediate scoring response. It also makes a mid-game replay easier to place: identify the half-inning before comparing the situation with a later highlight.
Useful answers
Does bottom of the fifth mean the game is almost over?
No. It identifies the home team’s batting turn in the fifth inning. The remaining game depends on the competition rules and whether extra innings or other circumstances arise.
Why did the home team not bat in the ninth?
If the home team was already ahead after the visiting team’s final required turn, another home batting half was unnecessary. Check the final score and completed line score.
