Capstone: judge a hitter from a slash line

AVG/OBP/SLG — three numbers, one verdict. Ready to read them like a scout?

The slash line (AVG/OBP/SLG) is the standard shorthand for a hitter's season. Reading one is three quick checks: the OBP−AVG gap (walks), the SLG−AVG gap (ISO — power), and the absolute OBP (the out-avoidance bottom line).

How this stat lies to you

  • The slash line still hides park, league, and luck — that's Level 2's whole agenda.

2. A hitter's line is .280/.290/.400. What's the red flag?

3. Which is the single most important slash-line number?
