The run environment, before the starters
Mariners have scored 526 runs in 134 games (3.93 per game) with a .684 OPS. Blue Jays have scored 529 in 135 (3.92) with a .685 OPS. The pitching staffs have allowed 4.35 and 4.40 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Mariners | 64–70 | 3.93 | .684 | 4.10 | 1.24 | 4.35 |
| Blue Jays | 65–70 | 3.92 | .685 | 4.00 | 1.32 | 4.40 |
Reassembling the buckets
Unlisted averages 5.50 innings per start. Dylan Cease averages 6.01. 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 |
|---|---|---|---|---|---|
| Mariners (Unlisted) | 5.50 | 4.20 | 3.50 | 4.10 | 4.16 |
| Blue Jays (Dylan Cease) | 6.01 | 2.37 | 2.99 | 4.00 | 2.91 |
| Combined | 7.07 |
A combined 7.07 projected earned runs against a 3.5 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
Rogers Centre is listed at 328 feet to left, 375 feet to left center, 404 feet to center, 375 feet to right center, 328 feet to right, on artificial turf, retractable at 270 feet above sea level with a listed capacity of 49,282. 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
Team totals this tight have no cushion. A single homer plus a walk and a double is the whole bet.
What would falsify it
An early exit from the opposing starter, or a three-run inning before the fifth, breaks a 3.5 team total. The number is small enough that one cluster inning does it.
The position
Seattle Mariners Team Total Under 3.5 at -155, 2 units. A price of -155 implies a 60.8% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Unlisted for Mariners. Dylan Cease for Blue Jays. 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. Unlisted at — points of K−BB separation versus Dylan Cease at 25.0 is the comparison ERA hides.
