Tigers vs Guardians Prediction, September 6, 2026 | Under 7.0
Jackson Jobe vs Gavin Williams at Progressive Field
Published September 6, 2026 · MLB Prediction Data Lab
The posted total is 7.0. A naive add of season run rates (4.40 for Tigers, 4.03 for Guardians) gets you 8.44 combined runs. That is not the bet. The bet is that Jackson Jobe and Gavin Williams plus Progressive Field pull the night below that baseline. Partitioning each starter's own earned-run rate across expected innings and handing the remainder to each club's season staff rate returns 7.97 projected earned runs.

The two starters, measured per batter faced
Rate statistics expressed per nine innings reward pitchers who work deep. Expressing them as a share of batters faced removes that distortion. Jackson Jobe has faced 104 hitters. Gavin Williams has faced 657.
| Starter | BF | K% | BB% | K−BB | K/BB | Pitches/BF |
|---|---|---|---|---|---|---|
| Jackson Jobe | 104 | 18.3 | 9.6 | 8.7 | 1.90 | 3.93 |
| Gavin Williams | 657 | 33.0 | 7.6 | 25.4 | 4.34 | 3.98 |
| Starter | W-L | ERA | IP | WHIP | K/9 | BB/9 | HR/9 | Opp AVG |
|---|---|---|---|---|---|---|---|---|
| Jackson Jobe (R) | 1-2 | 4.63 | 23.1 | 1.46 | 7.33 | 3.86 | 1.54 | .267 |
| Gavin Williams (R) | 13-7 | 3.81 | 163.0 | 1.09 | 11.98 | 2.76 | 1.49 | .213 |
Jackson Jobe sits at a 4.63 ERA with a 1.46 WHIP and 10 walks in 23.1 innings. Gavin Williams sits at a 3.81 ERA with a 1.09 WHIP and 50 walks in 163.0 innings. Walks stabilize faster than earned runs, so the walk column is the more trustworthy August reading.
Direction inside the season
Season aggregates hide the last month. These are the prior starts, excluding today's outing so the table does not leak a result into a published prediction.
| Jackson Jobe — last starts | IP | ER | K | BB | H | HR | Pitches |
|---|---|---|---|---|---|---|---|
| 2026-08-08 | 5.0 | 0 | 4 | 1 | 1 | — | 71 |

The run environment, before the starters
Tigers have scored 625 runs in 142 games (4.40 per game) with a .712 OPS. Guardians have scored 577 in 143 (4.03) with a .685 OPS. The pitching staffs have allowed 4.04 and 4.14 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Tigers | 65–77 | 4.40 | .712 | 3.69 | 1.23 | 4.04 |
| Guardians | 72–71 | 4.03 | .685 | 3.76 | 1.26 | 4.14 |
Reassembling the buckets
Jackson Jobe averages 4.67 innings per start. Gavin Williams averages 5.82. Weight each starter's own earned run average across that length, then hand the remainder of the nine innings to his club's season staff rate. That is a conservative relief proxy — it mixes rotation and bullpen — and it is stated as a limitation, not hidden.
| Side | Starter IP | Starter ERA | Relief IP | Staff ERA | Projected ER |
|---|---|---|---|---|---|
| Tigers (Jackson Jobe) | 4.67 | 4.63 | 4.33 | 3.69 | 4.18 |
| Guardians (Gavin Williams) | 5.82 | 3.81 | 3.18 | 3.76 | 3.79 |
| Combined | 7.97 |
A combined 7.97 projected earned runs against a 7.0 total. Unearned runs are ignored. Neither starter hits his average length every night. The opposing lineups are not in the formula; they sit in the table above.
The park
Progressive Field is listed at 325 feet to left, 410 feet to left center, 405 feet to center, 375 feet to right center, 325 feet to right, on grass, open at 653 feet above sea level with a listed capacity of 34,830. Park dimensions do not decide a total by themselves. They decide whether a walk plus a ball in the air becomes two runs or a long out.
Where this reading is weakest
The season run rates do not want this number. Combined they sit at 8.44 against a 7.0 total, a gap of 1.44 runs that the starters and the park have to close. Jackson Jobe also allows 1.54 home runs per nine, and one three-run ball turns a low-event night into a push or a loss.
What would falsify it
A start from either pitcher that ends before the fifth with a pitch count above 95, or a walk total of four-plus from Jackson Jobe, is the cleanest failure signal. That is how a 7.0 total gets away: free baserunners, an early bullpen, and a second time through a lineup that already scores 4.40 runs a night on the higher side.
The position
Tigers/Guardians Under 7 at -115, 1 units. A price of -115 implies a 53.5% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Jackson Jobe for Tigers. Gavin Williams for Guardians. Those names come from the MLB probable-pitcher feed, not from a guessed rotation.
Why use batters-faced rates instead of ERA?
Earned run average is a counting result. Strikeout and walk rates as a share of batters faced describe the process that produced it, and they stabilize on a smaller sample. Jackson Jobe at 8.7 points of K−BB separation versus Gavin Williams at 25.4 is the comparison ERA hides.
