WHIP: the fantasy classic
Baserunners per inning — simple, popular… and blind to one huge thing. What?
WHIP is walks plus hits, divided by innings pitched: how many runners does this pitcher put on per inning? Elite is around 1.00, average about 1.28. It's beloved in fantasy leagues and it's a fine quick glance.
The blind spot
Half of WHIP is hits allowed — and hits on balls in play are heavily defense- and luck-dependent (the BABIP story, next level). A pitcher in front of gold gloves runs a shiny WHIP; the same pitcher in front of statues doesn't. It also treats a walk and a triple as the same 'one runner'.
Treat WHIP as a symptom report, not a diagnosis. When you want to know whose WHIP is real, look at the components you'll meet next: K%, BB%, and BABIP.
The formula (optional — skippable)
WHIP = (BB + H) ÷ IP
How this stat lies to you
- Hits allowed are heavily defense/luck-flavored — half the stat isn't fully the pitcher's.
- A walk and a double both count as '1', hiding damage quality.
- HBPs don't count at all, amusingly.
