SLASH LINE

Simply put, a slash line is the following:

Batting Average / On-Base Percentage / Slugging Percentage

It is called a slash line since the statistics are separated by slashes.

See? Simple.

Formulas to Calcluate Each Component of a SLASH:

  • Batting Average (AVG) = H / AB
  • On-Base Percentage (OBP) = H + BB + HBP / AB + BB +HBP + SF
    • Takes into account HITS & WALKS (BB)
    • After about 500 plate appearances, a player’s OBP is a good predictor of what their future OBP will be. Prior to 500 PA’s it is tough to hang your hat on
  • Slugging Percentage (SLG) = TB / AB
    • SLG and Isolated Power (ISO) are both good measures of a hitter’s ability to log extra bases (i.e. their power).

Generally speaking, an elite slash looks like this (or higher):

.300 / .400 / .500

    5. Lezcano 1979: .321 / .414 / .573

NOTE: An On-Base Plus Slugging Percentage (OPS) Percentage is calculated by adding the last two components of the slash:

OPS = On-Base Percentage + Slugging Percentage
