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. Nick Martinez has faced 618 hitters. Trevor Williams has faced 81.
| Starter | BF | K% | BB% | K−BB | K/BB | Pitches/BF |
|---|---|---|---|---|---|---|
| Nick Martinez | 618 | 14.7 | 3.6 | 11.2 | 4.14 | 3.48 |
| Trevor Williams | 81 | 28.4 | 8.6 | 19.8 | 3.29 | 4.37 |
| Starter | W-L | ERA | IP | WHIP | K/9 | BB/9 | HR/9 | Opp AVG |
|---|---|---|---|---|---|---|---|---|
| Nick Martinez (R) | 13-4 | 2.99 | 153.2 | 1.10 | 5.33 | 1.29 | 1.05 | .250 |
| Trevor Williams (R) | —-— | 3.93 | 18.1 | 1.42 | 11.29 | 3.44 | 1.47 | .271 |
Nick Martinez sits at a 2.99 ERA with a 1.10 WHIP and 22 walks in 153.2 innings. Trevor Williams sits at a 3.93 ERA with a 1.42 WHIP and 7 walks in 18.1 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.
| Nick Martinez — last starts | IP | ER | K | BB | H | HR | Pitches |

| 2026-08-05 | 5.2 | 0 | 4 | — | 6 | — | 75 |

The run environment, before the starters
Rays have scored 628 runs in 140 games (4.49 per game) with a .730 OPS. Rangers have scored 578 in 141 (4.10) with a .716 OPS. The pitching staffs have allowed 4.16 and 4.40 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| Rays | 83–57 | 4.49 | .730 | 3.79 | 1.15 | 4.16 |
| Rangers | 70–71 | 4.10 | .716 | 4.27 | 1.31 | 4.40 |
Reassembling the buckets
Nick Martinez averages 5.91 innings per start. Trevor Williams averages 5.50. 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 |
|---|---|---|---|---|---|
| Rays (Nick Martinez) | 5.91 | 2.99 | 3.09 | 3.79 | 3.26 |
| Rangers (Trevor Williams) | 5.50 | 3.93 | 3.50 | 4.27 | 4.06 |
| Combined | 7.33 |
A combined 7.33 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
Globe Life Field is listed at 329 feet to left, 372 feet to left center, 407 feet to center, 374 feet to right center, 326 feet to right, on artificial turf, retractable at 545 feet above sea level with a listed capacity of 40,000. 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 5.91 and 5.50 innings.
The position
Tampa Bay Rays Moneyline at 102, 1 units. A price of 102 implies a 49.5% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Nick Martinez for Rays. Trevor Williams for Rangers. 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. Nick Martinez at 11.2 points of K−BB separation versus Trevor Williams at 19.8 is the comparison ERA hides.
