The Boston Red Sox "checked in" on Los Angeles Angels shortstop Zach Neto and Washington Nationals shortstop/second baseman CJ Abrams during the 2026 season, per Jen McCaffrey of The Athletic. McCaffrey writes that the Red Sox ultimately determined that the asking prices for both players, which included top Boston shortstop prospect Franklin Arias and more, were too high. Still, it's noteworthy that the Red Sox could potentially be in the market for veteran infield help this winter. Boston got highly underwhelming production at shortstop in 2026 from Trevor Story, who has one year and $25 million remaining on his current contract. If the Red Sox feel that Arias is not ready to take over in 2027, they could look to make a move for a more established option. Both Neto and Abrams would likely see their fantasy value improved by a trade to Boston.

Boston Red Sox first baseman Triston Casas (wrist) could be a candidate to start the 2027 season in Triple-A, per Jen McCaffrey of The Athletic. Casas did not play at all in 2026 due to wrist, knee, and intercostal injuries. It's been a while since the 26-year-old was able to string together an extended stretch of health, as injuries limited him to just 112 plate appearances in 2025 and 243 plate appearances in 2024. However, Casas was productive in his lone healthy big league season, hitting .263 with 24 home runs across 502 plate appearances in 2023. If he can get back to full health, Casas could be a useful power bat for Boston. Still, the Red Sox currently have a logjam at first base/designated hitter between Willson Contreras, Roman Anthony, Masataka Yoshida, and Curtis Mead. Casas is a name for deeper-league fantasy managers to monitor, but he could be forced to prove he can still be productive at the lower levels before he gets another shot in the big leagues.

Jen McCaffrey of The Athletic writes that the Boston Red Sox failing to come to a long-term extension with catcher Adley Rutschman after giving up a prospect haul to acquire him at the 2026 trade deadline would be "pretty rough." McCaffrey also speculates that Rutschman would likely ask for somewhere around five years and $100 million from Boston. The 28-year-old is set to hit free agency after 2027. Across 410 plate appearances split between the Red Sox and the Baltimore Orioles in 2026, Rutschman hit .242/.315/.426 with 13 home runs, 60 RBI, and 44 runs scored. Rutschman could significantly improve his market if he can stay healthy for a full season and get his offensive numbers up closer to where they were in his peak season in 2023, when he posted an .809 OPS and 20 home runs across 687 plate appearances. Still, he may want the security of a long-term extension, and Boston could be looking to secure its catcher of the future.

The Houston Astros have released outfielder Nelson Velazquez, per Brian McTaggart of MLB.com. McTaggart reports that Velazquez will pursue an "opportunity with a club in Asia" upon his release. Across 113 plate appearances split between the Astros and the St. Louis Cardinals in 2026, Velazquez hit .188/.257/.406 with six home runs, 18 RBI, and 12 runs scored. The 27-year-old has flashed high-end power, logging a 14% barrel rate and a 45% hard-hit rate across 728 career big-league plate appearances. However, Velazquez has also consistently graded out as a poor defender in the outfield, and he struck out in 29.5% of his trips to the plate. He may get another chance to prove himself at the MLB level, but it sounds as though he will be playing somewhere in Asia in 2027.
