Last scored matchup
Jacob isn't on today's slate. He was last scored 10 days ago, at home against Houston Astros on Sunday, September 27, 2026. This page refreshes with new projections as soon as he's back in a lineup.
Season line
24 starts, 7-5, 5.47 ERA, 1.49 WHIP, 123.1 innings. He's struck out 112 over that span, against 58 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 left-handed
Jacob is a left-hander, and that matters more for a starter than it does for most hitters. Lineups get built specifically to attack lefties — managers stack right-handed bats against them — so the lineup he draws on a given night swings his projection further than a righty's would. The model prices the actual lineup rather than a season-long rate for exactly that reason. A stacked righty lineup is the spot where his strikeout projection comes down hardest.
His last 5 starts
Jacob has 16 strikeouts in 24.3 innings across his last 5 starts, a 5.9 K/9, with a 8.14 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
Jacob has 112 strikeouts and 58 walks in 123.3 innings this season — 8.2 K/9 against 4.2 BB/9, a 1.9-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
Jacob has made 27 starts this season, averaging 4.6 innings with a 5.47 ERA across them. In the 12 starts we hold detailed lines for, he got through five or more innings 10 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
Jacob is averaging 5.2 innings a start across his last 8 outings, with a high of 6.0 and about 92 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
Jacob hasn't started in 12 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
Jacob's high-water mark was Saturday, August 22, 2026 at HOU: 9 strikeouts over 6.0 innings, 1 earned run. 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, Jacob 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 Jacob specifically, he's coming off a 12-day gap.
