The Red Sox have signed first baseman Nathaniel Lowe for the remainder of the 2025 season. Lowe, 30, appeared in 119 games for the Washington Nationals this season, making 113 starts, but was released on Saturday after batting .216 with a .292 OBP and .373 slugging percentage.

Boston also recalled outfielder/infielder Nate Eaton from Triple-A Worcester, placed outfielder Rob Refsnyder (left oblique strain) on the 10-day IL and designated catcher Ali Sánchez for assignment. Sánchez spent six games on the active roster as a third catcher, recording just one plate appearance.

Veteran first baseman Nathaniel Lowe, 30, designated for assignment by the Washington Nationals earlier this month, and the Boston Red Sox are finalizing a deal, sources told ESPN, paving the way for him to join one of the strongest lineups in baseball.
