Not on the current slate
Zac hasn't been scored in 42 days — his last matchup was against Los Angeles Dodgers on Sunday, July 12, 2026. A gap that long usually means an injury, a minor-league option, or a roster move rather than a rest day. Everything below is his most recent real production, not a projection.
Season line
19 starts, 3-9, 6.34 ERA, 1.56 WHIP, 98.0 innings. He's struck out 61 over that span, against 31 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
Zac 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
Zac has 15 strikeouts in 28.3 innings across his last 5 starts, a 4.8 K/9, with a 8.58 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
Zac has 61 strikeouts and 31 walks in 98.0 innings this season — 5.6 K/9 against 2.8 BB/9, a 2.0-to-1 ratio. That's around league-typical control — enough to work deep when the lineup cooperates, not enough to bail him out of a bad matchup.
What his floor looks like
Zac has made 19 starts this season, averaging 5.2 innings with a 6.34 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
Zac is averaging 5.5 innings a start across his last 8 outings, with a high of 6.7 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.
A long gap since his last start
Zac hasn't started in 47 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
Zac's high-water mark was Saturday, May 23, 2026 against COL: 6 strikeouts over 5.3 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, Zac 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 Zac specifically, he's coming off a 47-day gap.
