Los Angeles Angels at Seattle Mariners: Final Score & Recap

The Seattle Mariners handed the Los Angeles Angels a lopsided 11-2 defeat at T-Mobile Park on April 4, 2023, a result that shifted the DiamondIQ model's estimate of a Seattle win from 54% before first pitch to 100% by game's end. The Mariners built their advantage methodically through the middle innings, erupting for two runs in the fourth, five in the fifth, and three more in the seventh to put the game firmly out of reach. Los Angeles managed only two runs on seven hits while committing two errors, and their lone threat in the top of the fifth ultimately fizzled.

The pivotal sequence of the game unfolded across the fourth and fifth innings, driven almost entirely by Teoscar Hernandez and Angels starter Jose Suarez. Hernandez delivered a home run in the fourth that added 10.0% to Seattle's win probability, then followed with another home run off Suarez in the fifth for an additional 9.5% swing, giving him a combined WPA of plus-18.6% on the two swings alone. Cal Raleigh further damaged Suarez in the fourth with a double worth 6.7% in win probability, finishing the game with a WPA of plus-9.4% and an RE24 of plus-2.2. The Angels' best chance to respond came in the top of the fifth, when Brandon Drury doubled off Luis Castillo for a 6.0% swing, but Matt Thaiss's strikeout to end the threat represented a 5.3% probability loss and effectively closed the door on an Angels comeback.

Luis Castillo was the dominant force on the mound, posting a WPA of plus-21.4% and neutralizing the Angels after Drury's double. Hernandez stood as the game's clear offensive catalyst with a WPA of plus-18.6% and an RE24 of plus-2.9, both totals leading all position players. The final margin of nine runs reflected a methodical dismantling rather than a single explosive moment, with Seattle's damage distributed across three separate innings and anchored by Hernandez's back-to-back long balls against a starter who could not escape the fifth.
