AI Intelligence Analysis

LEAN +1
Gilbert's elite control against Johnson's struggles points to a low-scoring game; UNDER 8.0 is the sharper angle versus the marginal LAA home-dog ML value.

Key Factors

  • SP quality clearly favors SEA: Gilbert 4.02 ERA (B, 27.1% K rate, elite command) vs Johnson 5.53 ERA (C+, 17.9% K rate) — Gilbert should dominate.
  • UNDER 8.0 shows 7.9% edge (54% model, 7.42 total) — supported directly by the SP quality gap.
  • Home dog LAA at +148 (40.3% implied vs 46% model) is a secondary 7pp edge, but historical support profile is only YELLOW (a supportive track record, n=26) — not a green light for larger sizing.
  • Weather is mild (73.4F, 7.3 mph wind out) — a minor over tilt that doesn't overcome the pitching-driven under case.
  • F5 shows LAA only +2.2pp — sharps aren't excited about the home dog specifically, reinforcing that the total is the better play.

Risk Factors

  • LAA is a well-below-.500 team; market may be correctly discounting them beyond just SP quality.
  • Gilbert could dominate to the point of a LAA blowout loss, which supports UNDER but hurts the home-dog ML lean.
  • historical support is YELLOW not GREEN on the ML side — sizing capped at 0.75 units.
Sharp MoneyWith ModelF5 shows LAA only +2.2pp — Gilbert's dominance appears priced in already.
