A Different Way to Measure Baseball Greatness

Unlike traditional statistics that evaluate a pitcher only after an entire season has been completed, Starting Pitcher Rating evaluates every individual start. Each performance receives an SPR grade based on the quality of that day's pitching, allowing pitchers to be measured by the consistency and quality of their performances over time.

The SPR database currently spans every Major League season from 1898 through 2026, creating one of the largest game-by-game historical starting pitcher databases available.

Why Grade Every Start?

Traditional baseball statistics are built by accumulating season totals. While season totals are incredibly valuable, they often hide how a pitcher actually performed throughout the season.

Two pitchers may finish with identical ERAs or WAR while taking completely different paths to get there. One pitcher may perform consistently over six months, while another alternates between dominant outings and difficult starts.

By evaluating every individual start, SPR measures consistency alongside dominance. Every performance contributes to a pitcher's overall SPR average, creating another way to study pitchers across careers, seasons, franchises, and baseball history.

Explore 127+ Years of Baseball History

Starting Pitcher Rating allows baseball fans to explore more than a century of pitching performances through searchable leaderboards, player pages, historical rankings, team rankings, era comparisons, and daily start grades.

Whether you're researching Cy Young, Nolan Ryan, Pedro Martinez, Clayton Kershaw, or your favorite pitcher from childhood, SPR is designed to make baseball history easy to explore.

Many users simply enjoy taking a trip through baseball history and rediscovering forgotten greats from every generation.
