Manaea has posted a 4.33 ERA in 27 innings of work, and has been particularly poor in his last two starts. He’s allowed at least four earned runs in each of those outings, giving up a homer in both appearances. The Mariners have been productive on offense, averaging 4.54 runs per game. They have bats that perform well against lefties, including Julio Rodriguez and Cal Raleigh. And starter Luis Castillo (8-6, 3.19 ERA) is having one of his better years so far in 2025.
