The Red Sox announced that first baseman Nathaniel Lowe has been designated for assignment by the Red Sox. Chris Cotillo of MassLive reported the move shortly before the official announcement. That opens a 40-man spot for Tristan Gray, who has been acquired from the Rays. The Sox are also designating right-hander Josh Winckowski for assignment, reports Ari Alexander of 7 News. That will open another 40-man spot, presumably for Boston to add someone ahead of today’s Rule 5 protection deadline.
The moves are effectively early non-tenders. Friday afternoon is the deadline for teams to decide whether or not to tender contracts to their arbitration-eligible and pre-arb players. But as mentioned, today is the deadline for adding players to the 40-man in order to protect them from the Rule 5 draft. By cutting these two players now, the Sox have made space for adding Gray and someone else in the coming hours.
It’s not a surprise that Boston isn’t bringing Lowe back. He was a midseason desperation addition. The Sox lost Triston Casas to injury early in the season, leaving a hole at first base. They had been patching that over with guys like Romy González and Abraham Toro. Lowe became available in August when the Nationals released him. He has a good overall track record but was having a bad season. The Sox were able to grab him for essentially nothing to bolster their first base group down the stretch.
The Sox also could have kept Lowe for 2026 via arbitration but it never seemed likely they would do so. He qualified for Super Two status going into 2023, giving him four arb passes instead of the usual three. He had already raised his salary to $10.3MM in 2025. MLBTR contributor Matt Swartz projected him for a $13.5MM salary in 2026. The Sox presumably had no intention of paying that after Lowe hit .228/.307/.381 for a 91 wRC+ this year. They have Casas potentially coming back in 2026 and they could also pursue external additions.
Technically, Boston has some time to try to trade Lowe but other teams presumably aren’t keen on him at that $13.5MM price point either. He will likely stay in DFA limbo until Friday and then be non-tendered, becoming a free agent.
Once he’s officially on the open market, he will be an interesting bounceback candidate. As mentioned, his 2025 season wasn’t good, but he was a solid everyday first baseman for the Rangers for many years. From 2021 to 2024, he got into at least 140 games in four straight seasons, including at least 157 in the first three. He launched between 16 and 27 home runs in each of those. He also had a walk rate of 12.5% or higher in three of the four. He had a combined .274/.359/.432 slash line and 124 wRC+ for that span. FanGraphs credited him with 10.8 wins above replacement.
That strong performance helped the Rangers win the 2023 World Series and also pushed Lowe’s salary up into eight-figure territory. Those factors combined with his down year to make him a clear non-tender candidate.
Based on his track record, some club should give Lowe a big deal at some point, though at a lesser price point than his projected arbitration salary. He will jump into a first base market that has already seen Josh Naylor come off the board. Pete Alonso, Ryan O’Hearn, Luis Arráez and others are still out there, while Christian Walker and Willson Contreras are potential trade candidates.
More to come.
