Dodgers vs Reds Prediction, September 16, 2026 | Under 8.5
Blake Snell vs Andrew Abbott at Great American Ball Park
Published September 16, 2026 · MLB Prediction Data Lab
The posted total is 8.5. A naive add of season run rates (4.96 for Dodgers, 4.14 for Reds) gets you 9.10 combined runs. That is not the bet. The bet is that Blake Snell and Andrew Abbott plus Great American Ball Park 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 7.42 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. Blake Snell has faced 154 hitters. Andrew Abbott has faced 679.
| Starter | BF | K% | BB% | K−BB | K/BB | Pitches/BF |
|---|---|---|---|---|---|---|
| Blake Snell | 154 | 33.1 | 10.4 | 22.7 | 3.19 | 4.19 |
| Andrew Abbott | 679 | 17.7 | 10.3 | 7.4 | 1.71 | 3.93 |
| Starter | W-L | ERA | IP | WHIP | K/9 | BB/9 | HR/9 | Opp AVG |
|---|---|---|---|---|---|---|---|---|
| Blake Snell (L) | 4-1 | 1.91 | 37.2 | 1.09 | 12.19 | 3.82 | 0.00 | .185 |
| Andrew Abbott (L) | 6-11 | 4.78 | 154.1 | 1.46 | 7.00 | 4.08 | 1.40 | .260 |
Blake Snell sits at a 1.91 ERA with a 1.09 WHIP and 16 walks in 37.2 innings. Andrew Abbott sits at a 4.78 ERA with a 1.46 WHIP and 70 walks in 154.1 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.
| Blake Snell — last starts | IP | ER | K | BB | H | HR | Pitches |

| 2026-08-17 | 6.0 | 1 | 5 | 3 | 2 | — | 90 |

The run environment, before the starters
Dodgers have scored 749 runs in 151 games (4.96 per game) with a .758 OPS. Reds have scored 625 in 151 (4.14) with a .701 OPS. The pitching staffs have allowed 3.79 and 5.15 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Dodgers | 92–59 | 4.96 | .758 | 3.64 | 1.16 | 3.79 |
| Reds | 70–81 | 4.14 | .701 | 4.87 | 1.44 | 5.15 |
Reassembling the buckets
Blake Snell averages 5.38 innings per start. Andrew Abbott averages 5.14. 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 |
|---|---|---|---|---|---|
| Dodgers (Blake Snell) | 5.38 | 1.91 | 3.62 | 3.64 | 2.61 |
| Reds (Andrew Abbott) | 5.14 | 4.78 | 3.86 | 4.87 | 4.82 |
| Combined | 7.42 |
A combined 7.42 projected earned runs against a 8.5 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
Great American Ball Park is listed at 328 feet to left, 379 feet to left center, 404 feet to center, 370 feet to right center, 325 feet to right, on grass, open at 535 feet above sea level with a listed capacity of 42,319. 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 9.10 against a 8.5 total, a gap of 0.60 runs that the starters and the park have to close. Andrew Abbott also allows 1.40 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 Andrew Abbott, is the cleanest failure signal. That is how a 8.5 total gets away: free baserunners, an early bullpen, and a second time through a lineup that already scores 4.96 runs a night on the higher side.
The position
Los Angeles Dodgers/Cincinnati Reds Under 8.5 at -120, 2 units. A price of -120 implies a 54.5% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Blake Snell for Dodgers. Andrew Abbott for Reds. 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. Blake Snell at 22.7 points of K−BB separation versus Andrew Abbott at 7.4 is the comparison ERA hides.
