Last scored matchup
Spencer isn't on today's slate. He was last scored 3 days ago, away at Chicago White Sox on Thursday, August 20, 2026. This page refreshes with new projections as soon as he's back in a lineup.
Season line
8 starts, 4-2, 5.31 ERA, 1.36 WHIP, 39.0 innings. He's struck out 46 over that span, against 20 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
Spencer 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
Spencer has 28 strikeouts in 24.3 innings across his last 5 starts, a 10.4 K/9, with a 7.03 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.
Strikeouts and control
Spencer has 46 strikeouts and 20 walks in 39.0 innings this season — 10.6 K/9 against 4.6 BB/9, a 2.3-to-1 ratio. That walk rate is the risk in every projection on him. Free passes run up pitch counts, and a short outing caps the strikeout and outs numbers no matter how favourable the lineup looks. His floor is genuinely lower than his stuff suggests.
What his floor looks like
Spencer has made 8 starts this season, averaging 4.9 innings with a 5.31 ERA across them. In the 8 starts we hold detailed lines for, he got through five or more innings 6 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
Spencer is averaging 4.9 innings a start across his last 8 outings, with a high of 6.3 and about 86 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.
A long gap since his last start
Spencer hasn't started in 72 days. That's the single most useful warning on a pitcher's page, and it's the model's weakest spot. A gap that long usually means an injured-list stint, and a first start back is often on a strict pitch limit that no stat line reveals — books frequently don't post an outs line at all in that spot. Our projection is built on his healthy workload, so it will overshoot a shortened rehab start. Read any projection here with that in mind until he's stretched back out.
His best start in the log
Spencer's high-water mark was Thursday, May 21, 2026 at MIA: 9 strikeouts over 6.3 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, Spencer 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. For Spencer specifically, he's coming off a 72-day gap.
