Pitcher Projections

How to read MLB pitcher strikeout projections

Each probable starter on today's slate carries a projected strikeout total alongside ceiling context — the modelled chance of clearing higher strikeout thresholds such as 8, 9, or 10 punchouts. The projection is a central estimate for the outing; the ceiling figures describe how much upside sits above it. Two pitchers can share a projected total and still look very different once their ceilings are compared: one may be a steady mid-volume arm, the other a higher-variance strikeout threat.

Expected outs is shown next to each projection because strikeout totals are bounded by how long a starter is likely to stay in the game.

What can influence a pitcher strikeout projection

Strikeout projections are assembled from public, observable inputs. At a high level the model considers:

• Pitcher strikeout ability — the starter's demonstrated capacity to miss bats.
• Opponent strikeout tendencies — how often the lineup they face strikes out relative to the league, including team strikeout rates and splits by pitcher handedness.
• Workload and expected outs — the innings the starter is realistically in line to record.
• Handedness and matchup context — how the opposing lineup is constructed against this arm.
• Recent form — current stuff and command indicators where they carry signal.
• Lineup composition — confirmed or expected batting orders, which change the mix of hitters faced.

The internal mechanics that combine these inputs are not published.

Why pitcher projections move during the day

Pitcher strikeout projections are among the most volatile on the slate, and they move for concrete reasons. A confirmed lineup can raise or lower a projection meaningfully if a high-strikeout regular sits or a contact bat returns. Bullpen availability and recent pitch counts shift how deep a starter is expected to go, which moves expected outs and every threshold above it. Late scratches replace a starter entirely. Because of that, the stamp above the board matters more here than on most pages — an early build and a post-lineup build can differ substantially for the same pitcher.

These are projections, not guarantees

A strikeout projection is a central estimate with real variance around it. Starters beat and miss their projected totals routinely; the ceiling percentages exist precisely to describe that spread rather than hide it. EdgeRanked publishes the model's strikeout calls and then grades them against actual results in the results archive, including the ones it got wrong.
