Postgame review

Decision coverage note

Decision coverage was incomplete in the pitcher strikeout lane (6 opportunities expired despite a prior decision opportunity) and the additional pitcher props lane (28 opportunities expired without a decision). This recap is complete for the 6 settled Picks that were actually recorded, but the slate does not meet full-lifecycle acceptance. No missing decision was reconstructed, and these incidents do not count as Picks or change the record above.

Postgame review

Won: MIA +150

MIA got the result in a LAD 3, MIA 4 final. The BetRivers +150 ticket added +1.50 units to the game-pick record.

The pregame case started with BetRivers MIA +150. We made the side 40.2%; the price needed 40.0%. That left 0.2 percentage points of room over the price's break-even mark. The strongest public counterweight was Long-run team strength, which pulled 0.90 probability points away from MIA. LAD carried the higher starter rating: Tyler Phillips rated 46.9, compared with Tyler Glasnow at 60.3. The two confirmed lineups graded about even: MIA 52.5, LAD 51.0. The top displayed hitters were Javier Sanoja (55.2) and Max Muncy (54.9). LAD had the higher bullpen rating: MIA 49.5, LAD 52.5.

The result matched both the side and the saved price read. That is encouraging, not conclusive; the same profile still has to repeat before any live weight changes.

Postgame review

Lost: PHI +131

PHI did not get there in a PHI 2, ATL 12 final. The saved Lowvig +131 price cost 1.00 unit on the game-pick record.

The pregame case started with Lowvig PHI +131. We made the side 43.5%; the price needed 43.3%. That left 0.2 percentage points of room over the price's break-even mark. The strongest public push toward PHI was Long-run team strength, worth 0.15 probability points in the saved calculation. ATL carried the higher starter rating: Tim Mayza rated 52.1, compared with Tyler Mahle at 55.5. The two confirmed lineups graded about even: PHI 50.6, ATL 49.4. The top displayed hitters were Bryce Harper (58.0) and Ronald Acuna Jr. (53.5). ATL had the higher bullpen rating: PHI 48.6, ATL 51.5.

The price case was there; the result was not. We will compare this starter, lineup, and bullpen profile with future frozen reads before deciding whether the miss was noise or a repeatable blind spot.
