Nathaniel Lowe is headed to the Boston Red Sox on a prorated major‑league minimum deal, giving Boston a veteran left‑handed bat to stabilize the first‑base mix after Triston Casas’ season‑ending knee injury.

Lowe, who spent four solid seasons with the Rangers and was with Washington prior to this move, brings steady production against righties (.MVP-ish power割) and a tracked power spike against right-handed pitching (14 homers in 337 PAs this year). In Fenway, he could join a left‑side platoon role that currently features Abraham Toro and Romy Gonzalez, providing Boston with a meaningful floor while giving upside if he recaptures form. The Sox rank among the league’s run leaders and now have another veteran bat to lean on as they chase a playoff push.

Beyond Lowe, the piece notes internal depth with Kristian Campbell advancing at Triple‑A, Vaughn Grissom continuing to show upside, and top prospect Jhostynxon Garcia posting big power numbers in the minors. The Nationals, who designated Lowe for assignment, will owe most of the remainder of his $10.3 million salary this year, and the move carries arbitration sensitivity for 2026. The deal tightens Boston’s 1B platoon and preserves flexibility for the postseason chase.
