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. Davis Martin has faced 530 hitters. Hayden Wesneski has faced 133.
| Starter | BF | K% | BB% | K−BB | K/BB | Pitches/BF |
|---|---|---|---|---|---|---|
| Davis Martin | 530 | 20.9 | 7.4 | 13.6 | 2.85 | 3.84 |
| Hayden Wesneski | 133 | 21.1 | 9.0 | 12.0 | 2.33 | 3.78 |
| Starter | W-L | ERA | IP | WHIP | K/9 | BB/9 | HR/9 | Opp AVG |
|---|---|---|---|---|---|---|---|---|
| Davis Martin (R) | 9-6 | 4.32 | 125.0 | 1.33 | 7.99 | 2.81 | 0.86 | .266 |
| Hayden Wesneski (R) | 4-1 | 3.86 | 32.2 | 1.19 | 7.71 | 3.31 | 0.55 | .229 |
Davis Martin sits at a 4.32 ERA with a 1.33 WHIP and 39 walks in 125.0 innings. Hayden Wesneski sits at a 3.86 ERA with a 1.19 WHIP and 12 walks in 32.2 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.
| Davis Martin — last starts | IP | ER | K | BB | H | HR | Pitches |
|---|---|---|---|---|---|---|---|
| 2026-07-24 | 5.0 | 4 | 3 | — | 6 | — | 88 |

| 2026-08-13 | 2.0 | 3 | 3 | 1 | 2 | 2 | 35 |
| Hayden Wesneski — last starts | IP | ER | K | BB | H | HR | Pitches |
|---|---|---|---|---|---|---|---|

The run environment, before the starters
White Sox have scored 660 runs in 138 games (4.78 per game) with a .727 OPS. Astros have scored 631 in 139 (4.54) with a .724 OPS. The pitching staffs have allowed 4.46 and 4.86 runs per game.
| Club | Record | R/G | OPS | Staff ERA | Staff WHIP | RA/G |
|---|---|---|---|---|---|---|
| White Sox | 73–65 | 4.78 | .727 | 4.14 | 1.31 | 4.46 |
| Astros | 70–69 | 4.54 | .724 | 4.61 | 1.37 | 4.86 |
Reassembling the buckets
Davis Martin averages 5.21 innings per start. Hayden Wesneski averages 5.44. 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 |
|---|---|---|---|---|---|
| White Sox (Davis Martin) | 5.21 | 4.32 | 3.79 | 4.14 | 4.24 |
| Astros (Hayden Wesneski) | 5.44 | 3.86 | 3.56 | 4.61 | 4.16 |
| Combined | 8.40 |
A combined 8.40 projected earned runs against a 8.5 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
Daikin Park is listed at 315 feet to left, 362 feet to left center, 409 feet to center, 373 feet to right center, 326 feet to right, on grass, retractable at 45 feet above sea level with a listed capacity of 41,000. 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
If both starters hit their season length and staff rates hold, the partition sits at 8.40 earned runs. That is not automatically above 8.5 once unearned runs and sequencing are stripped out.
What would falsify it
Two starters working into the seventh with fewer than two walks combined would be the clearest miss. An over at 8.5 needs traffic and innings that leak.
The position
White Sox/Astros Over 8.5 at -115, 1 units. A price of -115 implies a 53.5% break-even. Grade it against this published number. If a listed starter is scratched, the play is void.

Who is on the mound?
Davis Martin for White Sox. Hayden Wesneski for Astros. 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. Davis Martin at 13.6 points of K−BB separation versus Hayden Wesneski at 12.0 is the comparison ERA hides.
