The Boston Red Sox surrendered eight or more runs in five consecutive games, the fourth time in franchise history after occurrences in 2020, 1930, and 1909. The streak coincided with a three-game series loss at Fenway against the Seattle Mariners, who scored 25 runs and collected 37 hits across the set and won the final two games to complete the series. In the series finale Seattle beat Boston 8-3, with Roman Anthony hitting a solo home run off Michael Rucker that traveled 370 feet at 102.6 mph with a 32.0 degree launch angle. Mariners hitters produced at least four runs in a single inning in each game of the series, and Boston managers used an extended portion of the bullpen over the set. Seattle’s offense piling up multi-inning outbursts helped it keep pushing for playoff positioning, while Boston faces immediate pitching strain and bullpen depletion going into upcoming matchups against Baltimore and Cleveland.
