Michael King Over 17.5 Pitcher Outs: Twenty One Of Thirty, And Now He Has To Do It At Coors

What The Number Is Asking

The line on King today is 17.5 outs. In plain English: does he finish the sixth inning? Get the 18th out and the over cashes. Leave with two outs in the sixth and it doesn’t.

The over is posted at -125 and the under at -115. Take the vig off both sides and the market has the over at roughly 50.9 percent, barely better than a coin flip. His own season says 70.00.

That’s a real disagreement. Usually when a book and a game log disagree this much, the book knows something the log doesn’t. Here the thing it knows isn’t a secret. It’s the ballpark.

First pitch is 1:10 local at Coors Field, 12:10 Pacific. The San Diego Padres (83 and 69, 9 and 1 over their last 10, holding the third wild card spot) against a Colorado Rockies team at 56 and 96 that has lost 9 of its last 10. Game time forecast: 77 degrees, wind 5 mph out to left.

Every 2026 Start

Twenty one greens, nine reds. He’s averaging exactly 17.50 outs a start, which is the line itself, and needing 5.33 pitches for every out. The full season line: 30 starts, 175.0 innings, a 3.03 ERA and a 1.15 WHIP, with 148 strikeouts and 66 walks.

The Shape Of It

Look at that 18 bar. Fifteen of his 30 starts ended at exactly 18 outs. Six innings and out is the default setting in San Diego, and it is also the thinnest possible way to clear this number. Only six starts went past 18. So this prop isn’t really asking whether King pitches deep. It’s asking whether he gets the last out of the sixth, the way he usually does.

The nine misses split two ways. Two stopped at 17, one out short. The other seven stopped at 15 or fewer, and those are the starts where something went wrong early.

Hot, And Getting Hotter

Nine of his last 10 starts cleared 17.5, and the last five all did: 20, 21, 18, 18, 21. Over those five he threw 100, 98, 96, 96 and 96 pitches, so San Diego is letting him work right around 100 when the game is close.

The one miss in that stretch was August 3 in Arizona: 5.0 innings, 104 pitches, 15 outs. That’s the template for how this goes wrong. It’s not a quick hook. It’s a pitch count that runs out before the innings do.

Efficiency Is The Whole Game

At 5.33 pitches an out, 18 outs costs him about 96 pitches. That is almost exactly what he’s been allowed lately, which means there’s very little room for a laborious inning.

And that’s the worry at Coors. Four of his nine short starts came on 97 pitches or more. He didn’t get pulled because he was fine. He got pulled because traffic ran his count up.

Coors Field Is The Whole Argument Against

Games at Coors Field are averaging 11.38 total runs in 2026, across 74 games. Everywhere else in the majors it’s 8.90. The Rockies score 5.15 runs a game at home and carry a .781 OPS at home, against .742 overall, which ranks 5th in baseball despite the record.

The three games already played in this series went 8 and 7, 3 and 9, and 9 and 3. Nobody has pitched cleanly this week.

King has faced Colorado once, on July 28 at Petco Park: 6.0 innings, 98 pitches, 18 outs, 4 earned runs and 2 home runs allowed. He got the 18th out, but he needed nearly every pitch to do it, and that was at sea level.

The Lineup Cuts Both Ways

Colorado swings early. The Rockies see 3.75 pitches per plate appearance, the fewest in baseball, against a league average of 3.89. That is a real help to a pitcher trying to stretch 96 pitches into six innings. Quick at bats end innings.

They also strike out. A 22.77 percent strikeout rate, 9th highest in the majors, and a .755 OPS against right handed pitching. A lineup that chases and swings early is the kind that lets a starter save pitches, as long as the balls in play don’t fall.

At Coors, more of them fall. That’s the tension on this page.

Why This Row And Not The Others

Bovada had props posted on three games when this board was read: 16 posted sides on 8 pitchers, all 16 measured against at least eight 2026 starts. 6 of the 16 beat their own price. The median gap is -3.22 points, which is what a normal board looks like: most rows lose to the price.

Nolan McLean, over 5.5 strikeouts at -130 against Philadelphia, reads as +12.44. Twenty of 29 is a real sample. But three of his last five went 3, 4 and 5, so the recent log is already leaning away.

King’s own strikeout over, 4.5 at +110, reads as +12.38. Eighteen of 30. It rides on the same Colorado swing rate, and it doesn’t need him to survive the sixth.

What Would Make This Wrong

The ballpark. An 11.38 run environment is where pitch counts go to die. One long inning and the sixth never comes.

The margin. Half his starts ended at exactly 18. The over lives on one out, every time.

The price. A book hanging -125 on a pitcher who’s cleared this in 9 of 10 is telling you it thinks Denver changes the math. It sees bullpen plans and lineup cards a game log never will.

What cuts the other way. The quickest swinging lineup in baseball, a pitcher who has gone six in 21 of 30, and a team chasing a wild card spot that has every reason to lean on its best starter.
