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. Cristopher Sánchez has faced 805 hitters. Jonah Tong has faced 91.
| Starter | BF | K% | BB% | K−BB | K/BB | Pitches/BF |
|---|---|---|---|---|---|---|
| Cristopher Sánchez | 805 | 26.7 | 5.5 | 21.2 | 4.89 | 3.68 |
| Jonah Tong | 91 | 22.0 | 9.9 | 12.1 | 2.22 | 3.92 |
| Starter | W-L | ERA | IP | WHIP | K/9 | BB/9 | HR/9 | Opp AVG |
|---|---|---|---|---|---|---|---|---|
| Cristopher Sánchez (L) | 17-6 | 2.93 | 193.2 | 1.22 | 9.99 | 2.04 | 0.79 | .258 |
| Jonah Tong (R) | 2-1 | 3.43 | 21.0 | 1.19 | 8.57 | 3.86 | 0.86 | .203 |

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.
| Cristopher Sánchez — last starts | IP | ER | K | BB | H | HR | Pitches |

The run environment, before the starters
Phillies have scored 690 runs in 155 games (4.45 per game) with a .710 OPS. Mets have scored 666 in 155 (4.30) with a .704 OPS. The pitching staffs have allowed 4.30 and 4.53 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Phillies | 85–70 | 4.45 | .710 | 4.02 | 1.29 | 4.30 |
| Mets | 71–84 | 4.30 | .704 | 4.15 | 1.30 | 4.53 |
Reassembling the buckets
Cristopher Sánchez averages 6.25 innings per start. Jonah Tong averages 10.50. 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 |
|---|---|---|---|---|---|
| Phillies (Cristopher Sánchez) | 6.25 | 2.93 | 2.75 | 4.02 | 3.26 |
| Mets (Jonah Tong) | 10.50 | 3.43 | 0.00 | 4.15 | 4.00 |
| Combined | 7.27 |
A combined 7.27 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
Citi Field is listed at 335 feet to left, 370 feet to left center, 408 feet to center, 380 feet to right center, 330 feet to right, on grass, open at 10 feet above sea level with a listed capacity of 41,922. 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 6.25 and 10.50 innings.
The position
Phillies Moneyline at -166, 1.5 units. A price of -166 implies a 62.4% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Cristopher Sánchez for Phillies. Jonah Tong for Mets. 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. Cristopher Sánchez at 21.2 points of K−BB separation versus Jonah Tong at 12.1 is the comparison ERA hides.
