Last scored matchup
Tanner isn't on today's slate. He was last scored 10 days ago, away at Chicago White Sox on Sunday, September 27, 2026. This page refreshes with new projections as soon as he's back in a lineup.
Season line
12 starts, 1-6, 6.68 ERA, 1.66 WHIP, 103.2 innings. He's struck out 85 over that span, against 24 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
Tanner 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
Tanner has 16 strikeouts in 20.0 innings across his last 5 starts, a 7.2 K/9, with a 12.15 ERA over that stretch and 9 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
Tanner has 85 strikeouts and 24 walks in 103.7 innings this season — 7.4 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
Tanner has made 24 starts this season, averaging 4.3 innings with a 6.68 ERA across them. In the 12 starts we hold detailed lines for, he got through five or more innings 5 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
Tanner is averaging 4.5 innings a start across his last 8 outings, with a high of 7.0 and about 81 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
Tanner hasn't started in 13 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
Tanner's high-water mark was Saturday, September 12, 2026 at DET: 5 strikeouts over 4.0 innings, 4 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
Tanner's score comes from the matchup, not his reputation. The model weighs how the opposing lineup handles his handedness, how many batters he's likely to face given recent workload, the park, and the weather — then normalizes 0–100 against every other arm on the slate. How those factors are weighted is our own, and it re-tunes weekly against real outcomes. We publish the score and grade it in public; that's the half you can check.
What we'd flag
Read this page knowing what it can't do. It can't show you a line no book posted — coverage peaks around 87% for confirmed starters. It can't see a lineup change that happens after the projection publishes. And it can't tell you anything useful from one game, because the model is only measurable across a season-sized sample. For Tanner specifically, he's coming off a 13-day gap.
