Season line

24 starts, 8-10, 4.18 ERA, 1.36 WHIP, 140.0 innings. He's struck out 117 over that span, against 33 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

George 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

George has 13 strikeouts in 24.0 innings across his last 5 starts, a 4.9 K/9, with a 7.13 ERA over that stretch and 8 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.

Strikeouts and control

George has 117 strikeouts and 33 walks in 140.0 innings this season — 7.5 K/9 against 2.1 BB/9, a 3.5-to-1 ratio. That's strong control, and it does more for his projection than the raw strikeout number does. Walks are the fastest way to shorten a start — an arm that doesn't issue them gets deeper into games, which is what the outs and strikeout lines are really pricing.

What his floor looks like

George has made 24 starts this season, averaging 5.8 innings with a 4.18 ERA across them. In the 12 starts we hold detailed lines for, he got through five or more innings 8 times. That ratio is the honest read on his floor, and it's what separates an arm worth projecting on the outs board from one whose good starts are unpredictable enough that the market prices them better than we do.

How long he goes

George is averaging 5.5 innings a start across his last 8 outings, with a high of 8.0 and about 89 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

George's high-water mark was Wednesday, June 10, 2026 at BAL: 10 strikeouts over 6.0 innings, 3 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, George 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.
