Season line
5 starts, 3-1, 4.23 ERA, 1.23 WHIP, 27.2 innings. He's struck out 22 over that span, against 10 walks. This is the baseline the matchup adjusts from — the model starts here and then asks what the specific lineup he's facing does to strikeout arms, how the park plays, and how deep he's likely to go.
He throws right-handed
Hayden throws right-handed, which is the ordinary case and means fewer wild swings in the lineup he faces. Opposing managers aren't restacking against him the way they would a left-hander, so his projection moves more on the quality of the lineup than on its handedness. What does move it: how deep he's been going lately, and whether the lineup in front of him strikes out.
His last 5 starts
Hayden has 22 strikeouts in 27.7 innings across his last 5 starts, a 7.2 K/9, with a 4.23 ERA over that stretch and 10 walks. Strikeouts are the one pitcher market where our model has found real, graded room — projected workload and the specific lineup he draws move that number more than a season-long rate does. Start-by-start detail is in the log below.
How long he goes
Hayden is averaging 5.5 innings a start across his last 5 outings, with a high of 7.0 and about 82 pitches a night. He's not going deep, and that caps the strikeout and outs projections no matter how good the matchup looks — you can't strike out hitters you don't face. Expected batters faced is one of the bigger inputs to his score for exactly this reason.
His best start in the log
Hayden's high-water mark was Saturday, August 15, 2026 against SEA: 6 strikeouts over 4.0 innings, 5 earned runs. One start doesn't set a projection — the model works off the blend of his recent work against the specific lineup in front of him — but it does show the ceiling when the matchup lines up.
How the model reads him
Every arm on the slate goes through the same math, Hayden included. Opposing lineup, handedness, expected batters faced, park, weather — weighted, combined, and normalized 0–100. We keep the weighting to ourselves and re-tune it weekly on real results. What we don't keep is the record: every projection here is graded against the box score at the line the market offered.
What we'd flag
Three caveats worth carrying. Not every player gets a posted line — book coverage runs to about 87% for confirmed starters, so a blank line is the market's silence, not ours. Lineup changes land late enough to strand a projection published hours earlier. And judging any of this on a single night is meaningless; the model is tuned on hundreds of settled outcomes.
