What is a good WHIP in baseball?

An elite WHIP is below 1.00, meaning the pitcher allows fewer than one baserunner per inning. A WHIP of 1.00–1.15 is excellent, 1.15–1.30 is above average, 1.30–1.50 is average, and anything above 1.50 is below average at the major league level.

How do partial innings work in the WHIP formula?

Baseball records partial innings as .1 (one out, one-third of an inning) and .2 (two outs, two-thirds of an inning). This calculator converts those decimals into the correct fraction — 6.1 innings becomes 6.333 and 6.2 becomes 6.667 — before dividing.

Does WHIP include hit by pitches or errors?

No. WHIP counts only walks (base on balls) and hits. Hit batters, errors, and catcher's interference do not count. Intentional walks are included because they still put a runner on base.

How is WHIP different from ERA?

ERA measures earned runs allowed per nine innings and is affected by run support and defense. WHIP measures baserunners allowed per inning and is a more direct measure of a pitcher's command and contact management, independent of whether those runners scored.

What is the all-time MLB WHIP record?

Addie Joss holds the all-time MLB career WHIP record at 0.9678 for pitchers with at least 1,000 innings pitched. Among modern era starters, Pedro Martinez posted a single-season WHIP of 0.7373 in 2000, widely considered the best modern single-season mark.
