Friday’s Strikeout Prop Board: The Median Row Sits Under Its Own Price

What This Board Is

A strikeout prop has two numbers on it and most analysis only argues about one. The line is the first. The price is the second, and the price is what turns a hit rate into a verdict.

So the method here is deliberately crude and deliberately complete. For every pitcher scheduled to start on September 4 who has a posted strikeout number and at least five starts on the season, pull his 2026 game log, count what share of his own starts finished above tonight’s line, and put that share next to the break even percentage the posted price demands. If a pitcher has cleared 2.5 in 88 percent of his starts and the over is priced at minus 130, which needs 56.52 percent, the gap is 31.7 points.

Twenty nine lines were posted and twenty four are in the table. The five that are missing belong to pitchers with fewer than five 2026 starts, which on a September board means callups and rotation fill ins. None of them has been guessed at.

No opponent adjustment is applied in the table. No park factor, no weather, no umpire, no bullpen usage. Those matter and they are handled in words further down, not in the arithmetic, because burying an adjustment inside a number is how a board stops being checkable.

The Full Posted Board

Eleven of the twenty four sit above the rate their own price requires and thirteen sit below. The median gap is minus 2.35 points, which is the first negative median this desk has printed in a week. The spread is wide at both ends, plus 31.7 at the top and minus 26.7 at the bottom, so this is a board with real disagreement on it rather than a flat one.

The Top Of The Board Is Two Very Low Numbers

The two widest gaps tonight are both posted at 2.5, which is the lowest strikeout line a starting pitcher gets, and both belong to men who average well above it.

Jameson Taillon is over 2.5 at minus 130, a 56.52 percent break even, and he has cleared 2.5 in 15 of his 17 starts, 88.2 percent. He is not a strikeout pitcher by 2026 standards at 8.04 per nine, but he averages 4.41 a start and the posted number sits almost two strikeouts under that. Kansas City strikes out at 20.82 percent, on the soft side, which is presumably why the line is down here in the first place. The record says the line went too far.

Andre Pallante is the same shape. Over 2.5 at minus 165 needs 62.26 percent and he has cleared it in 18 of 24 starts, 75.0 percent, at 6.42 per nine and 4.04 a start. The opponent is Colorado at 22.84 percent and the game is at Coors, which is the argument against and it is a real one: Coors suppresses breaking ball movement and Pallante lives on it.

Both rows carry the same warning. A low line with a heavy minus price is the most crowded ticket on any board, and the market knows the same game logs the table does. The gap here is not a secret, it is a price that has chosen to sit on the wrong side of a very short number.

Both Aces In Philadelphia Sit Over Their Price

The best pitching matchup on the schedule produces two rows on the same side of the line, which does not happen often.

Cristopher Sánchez is over 6.5 at minus 115, a 53.49 percent break even, and has cleared 6.5 in 18 of 28 starts, 64.3 percent, at 10.37 per nine and 7.21 a start. Chris Sale is over 6.5 at minus 125, needing 55.56, and has cleared it in 15 of 24, 62.5 percent, at 11.06 per nine and 7.38 a start. Both are pitching against a lineup in the 21 to 22 percent strikeout band, so neither number is being propped up by a soft opponent.

The complication is the one thing this table cannot see. Two aces facing each other tends to produce a short, fast game, and a starter only reaches seven strikeouts if he is allowed to reach the sixth and seventh innings. Sale has thrown 144 innings across 24 starts, six a start, and 6.5 is a number that needs all six of them.

The Bottom Of The Board Is High Rates On High Lines

Every one of the five widest negative gaps belongs to a pitcher whose posted line sits above his own per start average, and in four of the five the market has moved the number rather than the price.

Jared Jones is the widest at minus 26.7. Over 6.5 at plus 120 needs 45.45 percent and he has cleared 6.5 in 3 of 16 starts, 18.8 percent. His rate is genuinely high at 10.28 per nine, and he still only averages 5.19 a start, because a 10 per nine rate over four and two thirds innings does not produce six strikeouts. The Angels strike out at 25.18 percent, second highest on the board, and that is what put the line at 6.5.

Cristian Javier at minus 21.5 is the same problem on a shorter sample. Over 4.5 at plus 115 needs 46.51 and he has cleared it in 2 of 8 starts, 25.0 percent, averaging 3.12. Eight starts is thin and the direction is not.

Blake Snell carries the highest posted line on the board at 7.5, and he is the only man here with the raw rate to justify it, 12.46 per nine. He has made five starts. He has cleared 7.5 in two of them, 40.0 percent, against a 60.00 break even. Five starts is the floor for inclusion, not a sample worth leaning on, and the row is in the table only because the rule that put it there applies to everyone.

Logan Gilbert at minus 16.7 is the cleanest example of a good pitcher on a bad number. Over 6.5 at minus 135 needs 57.45 percent and he has cleared it in 11 of 27 starts, 40.7 percent, at 9.32 per nine and 6.15 a start. The line is set four tenths above his own average and then priced as if it were under it.

The Middle Rows Worth Reading

Max Fried is the only plus money row in the top four. Over 4.5 at plus 120 needs 45.45 percent and he has cleared it in 9 of 16 starts, 56.2 percent, at 8.30 per nine. San Diego strikes out at 21.83 percent, mid table, and Fried has been efficient enough this season to reach the sixth inning most nights.

Nick Martinez at 3.5 plus 110 is the row that looks wrong and is not. He strikes out only 5.33 per nine, the lowest rate on the whole board, and averages exactly 3.50 a start, which is the posted line. He has still cleared it in 15 of 26, 57.7 percent, against a 47.62 break even, because a low variance pitcher who sits on his own average clears a line set at that average about as often as he misses it. This is the sort of row a projection model buries and a hit rate finds.

Ranger Suarez at minus 16.0 is the counterexample. Over 5.5 at minus 115 needs 53.49 and he has cleared it in 9 of 24, 37.5 percent, at 8.66 per nine against a Baltimore lineup striking out at 24.40 percent. The matchup is real and the record has not followed it.

Method, Line By Line

Own hit rate is the share of that pitcher’s 2026 games started in which his final strikeout total finished strictly above tonight’s posted line. Only games started are counted, so relief appearances are excluded, and a pitcher needs five of them to appear at all.

Break even is the American price converted to implied probability with no vig removal. Minus 165 becomes 165 divided by 265, which is 62.26 percent. Plus 120 becomes 100 divided by 220, which is 45.45 percent. Because the vig is left in, every break even in the table is slightly higher than a fair one, so the gap column is a conservative reading rather than a flattering one.

Opponent K rate is team strikeouts divided by team plate appearances for the 2026 season to date. Tonight’s board spans 19.28 percent at Arizona to 25.29 percent at Cincinnati, a 6.01 point spread.

The One Number To Keep

Across the twenty four measurable lines the median gap is minus 2.35 points. On a board this size, that means the typical posted number is set slightly ahead of the pitcher’s own record rather than behind it, and the eleven rows that clear their price are the exceptions rather than the pattern. The two that clear it by the most are both posted at 2.5, which is a reminder that the widest gaps on any board usually live at the ends of the range and not in the middle of it.
