Baseball offers many statistics, but a useful starting point is whether a hitter records a hit, reaches base and produces extra bases through contact. These questions distinguish several familiar measures. Compare records from compatible competitions and samples, rather than treating figures from different settings as automatically equivalent.

Batting average describes hit frequency

Batting average relates hits to official at-bats, but not every way of reaching base counts as a hit. It can describe how often a batter hits safely without fully measuring plate judgement or power. Similar averages can therefore accompany quite different offensive profiles and different effects on a team's opportunities.

Reaching base and hitting for power differ

On-base percentage emphasises reaching base and avoiding outs, while slugging percentage reflects the total bases produced by different kinds of hits. A hitter relying on walks and singles can contribute differently from one generating more extra-base contact. Reading both dimensions gives a broader picture than selecting one preferred number.

A combined measure still needs context

OPS adds on-base and slugging percentages and can support a quick overview. It does not explain every offensive detail. Ballpark, opposition, plate-appearance sample and role remain relevant. Use the numbers alongside contact and baserunning evidence so they help investigate the player rather than replacing the full description.
