It's obvious that Devers' absence will affect Cora's lineup, which will have a few fewer doubles and fewer home runs than usual. Cora's team won the first game of the series against the Mariners 2-0 in a game that was also the first in many years without Devers on the roster, but the Game 2 odds since their release suggested a tendency to bet in favor of the Mariners, to the point that Seattle closed as a -150 favorite. As many predicted, it was indeed a one-way game in favor of the Mariners, who, by the time Woo pitched five innings, were already winning 8-0.

Walker Buehler had another poor outing, his worst in his last four, allowing the Mariners eight earned runs. It seems the Red Sox front office's gamble on the ex-Dodger pitcher didn't pay off, while other fans are wondering if a lineup featuring leadoff hitters Duran, Toro, Anthony, and Narváez, like the one Cora fielded Tuesday, will be enough to compete for a playoff spot.

The Mariners certainly look like a Red Sox-level team, with a similar record but a deeper starting rotation. On Tuesday, they were able to muster some solid rallies, something they've struggled with this season, in another strong offensive outing for Raleigh, who hit their 27th home run of the season.

Our Boston Red Sox vs Seattle Mariners Prediction

The Red Sox's repeated history since 2024 is that when they manage to have a slightly higher record, they immediately regress. After a six-game winning streak, parting ways with Devers, at least among fans, generated discontent and criticism. At least their ace, Crochet, with a 6-4 record and a 2.24 ERA, will return to the mound for the rubber match of the series against the Mariners. Our prediction for Red Sox vs Mariners is: Under 6.5 runs.
