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. Ethan Pecko has faced 18 hitters. Will Warren has faced 535.
| Starter | BF | K% | BB% | K−BB | K/BB | Pitches/BF |
|---|---|---|---|---|---|---|
| Ethan Pecko | 18 | 22.2 | 16.7 | 5.6 | 1.33 | 4.94 |
| Will Warren | 535 | 22.8 | 8.0 | 14.8 | 2.84 | 3.92 |
| Starter | W-L | ERA | IP | WHIP | K/9 | BB/9 | HR/9 | Opp AVG |
|---|---|---|---|---|---|---|---|---|
| Ethan Pecko (R) | —-— | 4.91 | 3.2 | 1.64 | 9.82 | 7.36 | 0.00 | .214 |
| Will Warren (R) | 8-6 | 4.43 | 122.0 | 1.40 | 9.00 | 3.17 | 1.40 | .267 |
Ethan Pecko sits at a 4.91 ERA with a 1.64 WHIP and 3 walks in 3.2 innings. Will Warren sits at a 4.43 ERA with a 1.40 WHIP and 43 walks in 122.0 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.

The run environment, before the starters
Astros have scored 596 runs in 131 games (4.55 per game) with a .727 OPS. Yankees have scored 579 in 130 (4.45) with a .716 OPS. The pitching staffs have allowed 4.89 and 3.68 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Astros | 65–66 | 4.55 | .727 | 4.63 | 1.36 | 4.89 |
| Yankees | 74–56 | 4.45 | .716 | 3.20 | 1.17 | 3.68 |
Reassembling the buckets
Ethan Pecko averages 3.67 innings per start. Will Warren averages 5.08. 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 |
|---|---|---|---|---|---|
| Astros (Ethan Pecko) | 3.67 | 4.91 | 5.33 | 4.63 | 4.74 |
| Yankees (Will Warren) | 5.08 | 4.43 | 3.92 | 3.20 | 3.89 |
| Combined | 8.64 |
A combined 8.64 projected earned runs. 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 47,309. 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
Moneyline edges this thin die when the length assumption fails. If the better starter is out in the fourth, the staff rate takes over and the partition no longer applies.
What would falsify it
A short outing from the starter on the backed side, or a crooked inning against the relief bucket that the partition treats as average, is the miss. The model is only as good as the length assumption of 3.67 and 5.08 innings.
The position
New York Yankees Moneyline at -140, 1.5 units. A price of -140 implies a 58.3% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Ethan Pecko for Astros. Will Warren 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. Ethan Pecko at 5.6 points of K−BB separation versus Will Warren at 14.8 is the comparison ERA hides.
