Total Baserunners

baserunners = walks + hits_allowed

Baserunners per 9 Inn

per_9_baserunners = round((walks + hits_allowed) / innings_pitched * 9 * 10) / 10

How It Works

How WHIP Is Calculated

Formula

WHIP = (Walks + Hits) / Innings Pitched

WHIP measures the average number of baserunners a pitcher allows per inning.

Benchmarks

  • Below 1.00: Elite
  • 1.00-1.15: Very good
  • 1.15-1.30: Above average
  • 1.30-1.45: Average
  • Above 1.50: Below average
  • Worked Example

    25 walks and 85 hits allowed over 100 innings.

    walks = 25hits_allowed = 85innings_pitched = 100
    1. 01WHIP = (25 + 85) / 100 = 110 / 100 = 1.100
    2. 02Baserunners per 9 innings = 1.100 * 9 = 9.9
