Bryce Miller is on the mound for the Mariners. He has a 7.19 ERA in his last eight starts. And get this: The Mariners have allowed double-digit runs scored in each of his last four outings (11, 10, 22 and 19, respectively).
This is very much a fade of Bryce Miller who has been atrocious lately. Red Sox starter Patrick Sandoval hasn't been much better, but at least he's limiting runs and has an offense behind him that I trust far more than the Mariners offense. The criticisms for Sandoval are all valid and he's likely to give up some production in the first five, but he'll outduel Bryce Miller for a first five win.
In his last seven starts, Mariners RHP Bryce Miller is 0-5 with a 7.18 ERA. Over the last two weeks, the Seattle bullpen owns a not-so-solid 8.14 ERA. So Boston at home should find opportunities. Meanwhile, the Mariners have dropped five straight, scoring 0-1 runs in three of those games. Left-handed pitching has been a big issue for the Seattle lineup; Red Sox LHP Patrick Sandoval can give up his usual two runs over five-plus frames, then we pray the Boston relievers hold it down against the bottom-scoring lineup of 2026.
