MLB Daily Report — September 9

Wednesday's board is a K-prop card with zero confirmed lineups. Fifteen games, and the model's real edges are all on the mound — the router has no Attack and no Lean, just two Scout moneylines that are both missing prices. The story is the strikeout board: four legitimate overs, led by Hunter Brown, and a cold attack-K lane that says size them down.

Slate Overview

The board splits clean: a K-prop night (Brown, Bennett, Yamamoto, Gausman) and a gated moneyline board (SD and LAD both Scout-tier but missing prices). One game is fully blocked — TB@ATL has no Atlanta probable, so no K stake there. The attack-K lane went 0-2 yesterday, which is the honest reason every over today is a lean, not a full attack.

Game-by-Game Breakdown

MIN @ DET (5:10 PM EDT)

Zebby Matthews against Keider Montero. Matthews over 4.5 at +124 is a coin flip (p_over 0.505) — the plus money helps but the projection (5.02) barely clears the line. Montero's over 3.5 at +136 is dead (p_over 0.195). Nothing here survives the prices.

Targets: pass. Matthews over 4.5 track-only at +124.

TOR @ ATH (7:05 PM EDT)

Braydon Fisher against Brady Basso — both flagged RELIEVER/SHORT-LEASH, both unpriced. Fisher's L5 is relief appearances (0.87 IP average), Basso's is 1.87 IP. No K stake on either.

Targets: pass. Both starters are short-leash relievers.

STL @ SF (7:45 PM EDT)

Andre Pallante against Blade Tidwell. Pallante's over 3.5 at +100 is negative (p_over 0.340), Tidwell's over 4.5 at +102 is negative (p_over 0.317). Both K rows are dead.

Targets: pass.

TEX @ SEA (8:10 PM EDT)

Cody Bradford against Kade Anderson. Bradford's under 4.5 at -161 carries a +53.1 EV — but it's an under at the -160 limit, and unders are not our lane. Anderson's over 5.5 at +112 is dead (p_over 0.072).

Targets: pass. Bradford under 4.5 track-only at -161.

WSH @ SD (8:10 PM EDT, dome)

Jackson Kent against Walker Buehler. Kent's over 3.5 at -128 is a coin flip (p_over 0.521, negative EV both ways). Buehler's over 3.5 at -178 is dead (p_over 0.631 vs 64% break-even). The game side is SD Scout-tier (65.6%) but missing a price.

Targets: pass on K. SD ML is a Scout read gated on price.

CLE @ BAL (10:35 PM EDT)

Foster Griffin against Shane Baz. Griffin's over 5.5 at -114 is dead (p_over 0.247) — but his under 5.5 at -111 carries +43.1 EV, fed by Baltimore's 28.8% K%. Baz's over 4.5 at +100 is negative (p_over 0.393).

Targets: pass. Griffin under 5.5 track-only at -111.

HOU @ PHI (10:40 PM EDT)

Hunter Brown against Cristopher Sánchez. This is the top play on the board. Brown's over 4.5 at -140 carries a +25.9 EV with p_over 0.734 — the best price-plus-edge combination on the slate. His K/IP is climbing (1.059, L3 1.145) and he clears 4.5 by a strikeout and a half. Sánchez's over 6.5 at +102 is a coin flip (p_over 0.428).

Targets: Brown over 4.5 K (FD -140, 0.25u, top play).

NYM @ MIA (10:40 PM EDT, dome)

Robert Stock against Janson Junk — both flagged RELIEVER/SHORT-LEASH. Stock's over 4.5 at +116 is dead (p_over 0.081), Junk's over 3.5 at +106 is dead (p_over 0.071). The short-leash flags kill both.

Targets: pass.

LAA @ BOS (10:45 PM EDT)

Ryan Johnson against Jake Bennett. Bennett's over 4.5 at -153 carries a +22.1 EV with p_over 0.739 — the best matchup on the board against the Angels' league-high 28.8% K%. Johnson's over 3.5 at +102 is a coin flip (p_over 0.482).

Targets: Bennett over 4.5 K (FD -153, 0.25u).

COL @ NYY (11:05 PM EDT)

Tomoyuki Sugano against Will Warren. Sugano's over 3.5 at -111 is negative (p_over 0.421). Warren's over 5.5 at +122 is dead (p_over 0.108) — flagged LAST-APP-SHORT. Nothing here.

Targets: pass.

TB @ ATL (11:15 PM EDT)

Griffin Jax against a TBD Atlanta starter. Jax's over 4.5 at -111 is negative (p_over 0.398). The missing Atlanta probable blocks any K stake on this game regardless.

Targets: pass. Atlanta probable missing — game gated.

CHC @ MIL (11:40 PM EDT, dome)

Kevin Gausman against Logan Henderson. Gausman's over 5.5 at -104 carries a +13.6 EV with p_over 0.579 — solid but the thinnest of the four overs. Henderson's over 6.5 at +114 is dead (p_over 0.305).

Targets: Gausman over 5.5 K (FD -104, watch/track).

AZ @ KC (11:40 PM EDT)

Zac Gallen against Daniel Lynch IV. Gallen is unpriced and flagged IL-GAP 64d. Lynch's over 2.5 at -106 is dead (p_over 0.155) — flagged RELIEVER/SHORT-LEASH.

Targets: pass.

PIT @ CWS (11:40 PM EDT)

Lake Bachar against Davis Martin. Martin's under 4.5 at -104 shows a +81.1 EV — but he's flagged RELIEVER/SHORT-LEASH, which makes that number an artifact, not an edge. Bachar is unpriced and short-leash.

Targets: pass. Martin under 4.5 is an artifact-tier number, not a play.

CIN @ LAD (2:10 AM EDT)

Rhett Lowder against Yoshinobu Yamamoto. Yamamoto's over 7.5 at +100 carries a +15.3 EV with p_over 0.577 — even money on a pitcher who's cleared 7.5 in four of five against the second-highest-K lineup in baseball. Lowder's over 3.5 at -114 is a coin flip (p_over 0.374).

Targets: Yamamoto over 7.5 K (FD +100, 0.25u).

Show Your Work

The picks below are not a black box. Here is the model's number, the band around it, what we are assuming, the variables that actually decide it, and how we will grade it after first pitch.

Hunter Brown over 4.5 K (FD -140, 0.25u) — lean

• Model: K-distribution p_over 0.734 vs 58.3% break-even, +25.9 EV per $100. projK 5.97, K/IP 1.059 trending up.
• Confidence band: 65–78% over. The floor is his two 4-K games in the last six; the ceiling is the 10-K game and the climbing K/IP.
• Assumptions: Brown holds his K/IP uptrend rather than regressing to his 4-K floor games. No early hook.
• Key variables: Pitch count, PHI team K% (24.7, mid), and whether he clears 5 innings.
• Grade it by: 5+ K is a win. Exactly 4 K is the floor miss — the shape that bit the attack-K lane yesterday.

Jake Bennett over 4.5 K (FD -153, 0.25u) — lean

• Model: K-distribution p_over 0.739 vs 60.5% break-even, +22.1 EV per $100. projK 5.99 against the league's highest-K lineup (LAA 28.8%).
• Confidence band: 66–78% over. The matchup is the best on the board; the drag is the -153 price and his last two starts dipping to 4 K.
• Assumptions: The Angels keep striking out at their league-high clip. Bennett's K/IP uptrend holds.
• Key variables: LAA team K% (28.8), Bennett's K/IP trend, and whether he gets 5+ innings.
• Grade it by: 5+ K is a win. A 4-K night against a 28.8% K% lineup is the variance miss, not a bad read.

Yoshinobu Yamamoto over 7.5 K (FD +100, 0.25u) — lean

• Model: K-distribution p_over 0.577 vs 50.0% break-even, +15.3 EV per $100. projK 8.30 against CIN's 28.7% K%.
• Confidence band: 52–62% over. The 7.5 line is high, which is why the edge is thinner than Brown or Bennett.
• Assumptions: Yamamoto keeps clearing 7.5 at his recent rate (four of five). Cincinnati keeps striking out.
• Key variables: CIN team K% (28.7), Yamamoto's swing-and-miss rate, and whether he works deep enough to threaten 8.
• Grade it by: 8+ K is a win. A 7-K night is a push on the line — the plus money is what makes the thin edge worth a quarter unit.

Slate Shortlist

Best strikeout props: Brown over 4.5 (FD -140, top play), Bennett over 4.5 (FD -153, best matchup), Yamamoto over 7.5 (FD +100, plus money), Gausman over 5.5 (FD -104, watch).

Best 2+ hit candidates: none — 0 of 30 lineups confirmed, all hitter props track-only.

Best correlated builds: none pre-lock. No lineups, no SGP frames until the nines post.

Notes Before Lock

• 0 of 30 lineups confirmed — every hitter prop is track-only until the nines post
• Atlanta's probable is missing (TB@ATL) — no K stake on that game until it resolves
• Both Scout moneylines (SD, LAD) are missing prices — re-check at the next odds refresh
• The attack-K lane went 0-2 yesterday — every over today is sized as a lean, not an attack
• 7 pitchers carry RELIEVER/SHORT-LEASH flags — Martin's +81 under is an artifact, not an edge
• Yamamoto's +100 is price-sensitive — verify it's still there at lock

TL;DR

• Hunter Brown over 4.5 K (FD -140, 0.25u) — best price-plus-edge on the board, K/IP climbing
• Jake Bennett over 4.5 K (FD -153, 0.25u) — best matchup against the league's highest-K lineup
• Yoshinobu Yamamoto over 7.5 K (FD +100, 0.25u) — even money on a four-of-five clearer
• Kevin Gausman over 5.5 K (FD -104, watch) — solid but the thinnest edge of the four
• Pass: Martin under 4.5 (RELIEVER artifact), TB@ATL (no probable), both Scout MLs (no price)
• All hitter props: track-only — 0 of 30 lineups confirmed

Updates

• Revision 1 (11:00 AM EDT, September 9): Initial morning look. 0 of 30 lineups confirmed — all hitter props track-only. K-board built (25 priced, 4 unpriced). Router: 0 Attack, 0 Lean, 2 Scout (SD, LAD, both missing prices). Four K overs identified (Brown, Bennett, Yamamoto, Gausman), sized as leans given the attack-K lane's 0-2 yesterday. TB@ATL gated on missing Atlanta probable.
