What order does a slash line go in?

Always batting average, then on-base percentage, then slugging percentage: AVG/OBP/SLG. For example .281/.368/.444. OPS is usually quoted separately right after.

How do I read a slash line quickly?

The gap between AVG and OBP tells you plate discipline (walks); the gap between OBP and SLG tells you power. A wide OBP-to-SLG gap means a slugger; a narrow one means a contact-and-walks hitter.

Why compute all three together?

They share most of the same inputs, so entering hits, extra-base hits, walks, and at-bats once produces the whole line. It also keeps rounding consistent across the three stats.

Slash Line Calculator

The slash line packs a hitter's three core rate stats into one line — AVG/OBP/SLG — with OPS alongside. Enter one set of stats and get all four at once.

Formula

Slash line = AVG / OBP / SLG, OPS = OBP + SLG

Tiers are MLB rules of thumb. Youth and high school numbers run much higher and aren't directly comparable.

How it works

The slash line is just three rate stats displayed together. This tool computes batting average (H ÷ AB), on-base percentage ((H+BB+HBP) ÷ PA), and slugging percentage (total bases ÷ AB) from a single set of inputs, then adds OPS as OBP + SLG.
