Over 15 logged MLB games, Isaac Mattson has gone over 1.5 hits allowed 7 times (47%), and over their last 10 they have done it 6 times (60%). They average 1.6 hits allowed across those 15 games. Their last 5 average 2.6, 63% above their 1.6 across the full log. They have gone over 1.5 in each of their last 4. These are measured box-score results from Pittsburgh Pirates games, not a projection, and on their own they say nothing about whether tonight’s price is worth taking.
| Market | Logged games | Average | Most balanced line | Hit rate there |
|---|---|---|---|---|
| Strikeouts | 15 | 1.2 strikeouts | Over 1.5 | 4 of 15 (27%) |
| Hits Allowed | 15 | 1.6 hits allowed | Over 1.5 | 7 of 15 (47%) |
Every market Isaac Mattson is currently priced in, on the same row as the game it came from. A dash means the box score carried no value in that market for that game, which is not the same as a zero.

Counted from the same 15 logged games as the tables above. Measured history, not a projection and not a read on tonight's price.
| Percentile | Hits Allowed |
|---|---|
| Lowest logged game | 0 |
| 25th percentile | 0 |
| Median | 1 |
| 75th percentile | 3 |
| Highest logged game | 4 |
13 of 15 games (87%) landed between 0 and 3; 11 (73%) finished at or above the 1 median, and the spread from 0 to 4 is the whole range of the log. Nearest-rank, so every figure is a score Isaac Mattson actually recorded.
| Month | Logged games | Average |
|---|---|---|
| July 2026 | 9 | 1.9 |
| June 2026 | 4 | 0.3 |
| Gap | Logged games | Average |
|---|---|---|
| 1 day | 3 | 0.3 |
| 3 to 4 days | 6 | 1.7 |
| 5 or more days | 4 | 2.8 |
The gap is the distance to the previous game in this log, not a rest figure — a box score does not record a game a player sat out inside it.
| Opponent | Logged games | Average | Best |
|---|---|---|---|
| Washington Nationals | 2 | 2.5 | 3 |
| Milwaukee Brewers | 2 | 1 | 1 |
| Cleveland Guardians | 2 | 0.5 | 1 |
| Cincinnati Reds | 2 | 0 | 0 |
Most-faced in this log is Washington Nationals, 2 games at 2.5, best of 3. Counts sit beside every average because two meetings is a low bar; opponents faced once are left out.
Against their own 1 median rather than a posted line, Isaac Mattson's longest run at or above it is 7 games and the run open at the newest of the 15 is 4. Whether the bigger games cluster — not when the next one is.
| Market | Average | Spread | Reads as | Games |
|---|---|---|---|---|

Prop history for Isaac Mattson of the Pittsburgh Pirates. 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 live board carries a line for this player, it 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. No locks and no guaranteed wins. This is measured history and a price, and what you do with them is your decision.

This page keeps the measured history. When the live board carries a line for Isaac Mattson, it appears at the top of this page, and 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. Past performance does not predict future results, and Parlay Builder does not accept wagers, hold funds or settle bets.
