Sonny Gray vs Max Fried at Yankee Stadium
Published September 30, 2026 · MLB Prediction Data Lab
A team total of 3.5 is a one-side problem. The model is asking whether Max Fried can hold Red Sox under that number for nine innings, with the park and the opposing staff rate doing the rest of the work.
This is the largest stake on today's card. The other unders the same night load on the same run-environment factor; size the card as one bet, not seven independent shots. Full board: MLB picks today.

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.

The run environment, before the starters
Red Sox have scored 689 runs in 162 games (4.25 per game) with a .716 OPS. Yankees have scored 739 in 161 (4.59) with a .720 OPS. The pitching staffs have allowed 3.77 and 3.73 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Red Sox | 0–1 | 4.25 | .716 | 3.54 | 1.23 | 3.77 |
| Yankees | 1–0 | 4.59 | .720 | 3.24 | 1.17 | 3.73 |
Reassembling the buckets
Sonny Gray averages 5.83 innings per start. Max Fried averages 5.63. 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 |
|---|---|---|---|---|---|
| Red Sox (Sonny Gray) | 5.83 | 2.72 | 3.17 | 3.54 | 3.01 |
| Yankees (Max Fried) | 5.63 | 2.80 | 3.37 | 3.24 | 2.96 |
| Combined | 5.97 |
A combined 5.97 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
Yankee Stadium is listed at 318 feet to left, 399 feet to left center, 408 feet to center, 385 feet to right center, 314 feet to right, on grass, open at 55 feet above sea level with a listed capacity of 46,537. 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
Red Sox Team Total Under 3.5 at -154, 3 units. A price of -154 implies a 60.6% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Sonny Gray for Red Sox. Max Fried for Yankees. 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. Sonny Gray at 15.1 points of K−BB separation versus Max Fried at 16.4 is the comparison ERA hides.
