With no line posted, over 17 MLB games since July 2026, Gavin Williams has gone over a balanced line of 9.5 strikeouts 9 times (53%), and over their last 10 they have done it 4 times (40%). They average 8.6 strikeouts across those 17 games. Their last 5 average 7.4, 14% below their 8.6 this season (17 games). These are measured box-score results from Cleveland Guardians games, not a projection, and on their own they say nothing about whether the posted price is worth taking.

Counted from the same 17 logged games as the tables above. Measured history, not a projection and not a read on tonight's price.

| Median | 10 |
| 75th percentile | 11 |

10 of 17 games (59%) landed between 7 and 11; 9 (53%) finished at or above the 10 median, and the spread from 1 to 13 is the whole range of the log. Nearest-rank, so every figure is a score Gavin Williams actually recorded.

| September 2026 | 5 | 8.8 |

Prop history for Gavin Williams of the Cleveland Guardians. Nothing is priced right now, so what follows is the record in Strikeouts and Hits Allowed: how often they have finished above each line their own game log supports, what their average looks like at home and away, and how much they have moved lately against their own baseline. Every figure is counted from official MLB box scores, one row per game they actually played, and rebuilt daily. None of it is a forecast, and none of it is compared with a price: when the books post this market again the live board appears at the top of this page.
Calculated by the ParlayBuilder Prop Engine.
Every figure on this page is counted from official MLB box scores, one row per game actually played. No projections, and a game the player missed is absent rather than scored as a zero. Where a hit rate is compared with the live price, it is first pulled toward that price in proportion to how thin the sample is, so three-for-three does not read here as a certainty.
Past performance does not predict future results, and Parlay Builder does not accept wagers, hold funds or settle bets. This is measured history and a price, and what you do with them is your decision.
You must be 21+ (or older, where your jurisdiction sets a higher age) to bet. If gambling stops being fun, call or text 1-800-GAMBLER (1-800-426-2537) for free, confidential help.
Not while the MLB board is down. This page keeps the measured history in the meantime and the live board reappears at the top of it the morning after the books post this market: the address does not change, so a bookmark or a link keeps working.
How often they finished above each line their own distribution supports, over all their logged games and over the last ten and five, with the game count printed beside every rate. A percentage without a denominator is not a measurement, so none appears here without one.
No. It is a record of games that have been played, and it is not compared with any price because no price is posted. Past performance does not predict future results, and Parlay Builder does not accept wagers, hold funds or settle bets.
