The Red Sox designated Lowe for assignment Tuesday.
Lowe had been set to be non-tendered later this week, so this transaction just serves a way to remove him from the 40-man roster sooner. The veteran first baseman slashed only .228/.307/.381 with 18 home runs over 153 regular-season games between the Nationals and Red Sox in 2025. Lowe will become a free agent once he officially clears waivers.
