3 MLB Strikeout Props to Back on September 17: Nola, McLean, and King All Set to Rack Up Ks

Strikeout props are one of the most predictable markets in baseball when you know where to look, and Wednesday’s slate has three pitchers lined up against exactly the kind of matchups that make Ks easy to project. Two aces are squaring off in Queens, and a Cy Young-caliber arm is walking into the thin air of Coors Field looking to miss bats before the ball starts flying.

All three of these plays lean on a simple idea: workhorse strikeout pitchers facing lineups or ballparks that won’t get in their way. Here’s the breakdown on each one, and why the numbers back up betting the over.

Aaron Nola Over 5.5 Strikeouts vs. Mets

Aaron Nola has been striking out batters at a 5.5 K/g clip across 30 appearances this season, and Wednesday night’s matchup with the Mets gives him a real shot to clear this number again. Nola’s strikeout floor has been remarkably steady all year, and a division rival lineup that will see plenty of swing-and-miss stuff from a veteran who knows how to attack New York hitters gives this over real juice at +132.

The Phillies need length from their rotation down the stretch, and Nola pitching deep into games is exactly what keeps this prop alive into the sixth and seventh innings. He’s shown he can rack up strikeouts even in outings where the results haven’t gone his way this year, which is the profile you want in a strikeout prop — the whiffs are there regardless of how the final line reads.

Getting a plus-money price on a number this close to his season average is the kind of value that doesn’t come around often. Bettors tracking live odds on MLB odds should notice this line moving as the game gets closer, so locking it in early makes sense.

Nolan McLean Over 5.5 Strikeouts vs. Phillies

On the other side of the same game, Nolan McLean has been nothing short of dominant since arriving in the Mets rotation, and his 6.3 K/g average over 29 appearances makes him a strong bet to clear 5.5 strikeouts even against a Phillies lineup that’s playing meaningful September baseball. McLean has emerged as one of the National League’s top rookie strikeout artists, and this number sits comfortably below his season pace.

What makes McLean’s over so appealing at -104 is the swing-and-miss stuff he’s shown all year — a strikeout rate that ranks among the better marks for any starter, rookie or not. He’s carried a strong K:BB ratio deep into the season, a sign that the swings and misses are a real feature of his game and not a small-sample mirage.

Facing a Phillies lineup that will see a mix of swing-heavy hitters, McLean has the swing-and-miss arsenal to push well past this number. When a pitcher this good gets a number below his season average, that’s usually a sign the market hasn’t fully caught up yet.

Michael King Over 4.5 Strikeouts at Coors Field

Michael King heading to Coors Field brings the usual complications that come with pitching a mile above sea level, but this strikeout prop is set low enough — just 4.5 — that his 4.9 K/g average across 30 appearances should clear it without needing a vintage outing. King has been a strikeout-heavy arm for San Diego, and Coors Field’s thin air affects fly-ball distance far more than it affects a pitcher’s ability to miss bats with his stuff.

The Rockies lineup has struggled against quality pitching all season, and King bringing his full arsenal — including the sweeper and changeup that have generated whiffs all year — gives him a path to this number even in an unfamiliar ballpark. At +110, the price reflects some hesitation from bettors who see “Coors Field” and assume the worst, but a strikeout total this modest doesn’t require King to dominate, just to pitch a normal number of innings and get the swings and misses he usually gets.

This is the value play of the three: a strong strikeout arm getting a number that undersells his true talent level just because of the ballpark attached to it.

Lock These In

All three of these strikeout overs are built on pitchers performing at or near their season-long strikeout pace against matchups that shouldn’t slow them down. The numbers do the talking here, and the plus-money prices on two of the three make this a slate worth attacking.

• Aaron Nola Over 5.5 Strikeouts vs. Mets (+132)
• Nolan McLean Over 5.5 Strikeouts vs. Phillies (-104)
• Michael King Over 4.5 Strikeouts at Coors Field (+110)
