The Atlanta Braves and Houston Astros pulled off a trade on Wednesday, with the Braves acquiring infielder/outfielder Mauricio Dubon from the Astros in exchange for infielder Nick Allen, according to ESPN's Jeff Passan. The Braves have a glaring need at shortstop going into next season, but it's unclear if Dubon, a two-time Gold Glover, will play at the 6 primarily or be used as more of a utility man. The 31-year-old has played seven different positions in his seven big-league seasons, including 107 games at short and 214 at second base. Both Dubon and Allen are glove-first players, which doesn't make them as attractive in fantasy baseball. Dubon has had a .677 OPS the last three years in Houston, while Allen had just a .535 OPS while serving as the Braves' primary shortstop for much of 2025. Dubon has only 39 homers with a .257/.295/.374 slash line in his seven seasons in the majors.

After designating him for assignment on Tuesday, the New York Mets officially released right-hander Frankie Montas (elbow) on Wednesday, according to Anthony DiComo of MLB.com. Montas will go down as a huge bust signing for the Mets, as he ended up making only nine appearances (seven starts) for New York in 2025 while posting an ugly 6.28 ERA (5.33 FIP) and 1.60 WHIP with 32 strikeouts and 14 walks in 38 2/3 innings pitched. The 32-year-old veteran needed Tommy John surgery on his right elbow and will now miss the entire 2026 season. The Mets will owe him $17 million while he rehabs next year. The Dominican hurler teased fantasy managers back in 2021 with a 3.37 ERA and a career-high 207 strikeouts, but things began to fall apart health-wise shortly after he was acquired by the New York Yankees the following season. Montas did manage to make 30 starts in 2024 with the Reds and Brewers, but he was unable to rediscover the form he showed in Oakland.

The Boston Red Sox announced on Tuesday that they designated first baseman Nathaniel Lowe for assignment after acquiring infielder Tristan Gray from the Tampa Bay Rays in exchange for minor-league right-hander Luis Guerrero. Lowe began the 2025 campaign playing for the Washington Nationals, where he hit just .216/.292/.373 with a career-low .665 OPS, 16 home runs, 68 RBI, 50 runs scored, and a 130:47 K:BB in 119 games played. The 30-year-old left-handed slugger finished up the year in Boston, where he went 28-for-100 (.280) with two bombs, 16 RBI, and 14 runs scored in 34 regular-season contests. Lowe should attract some interest on the free-agent market this winter as a left-handed power bat, but in a best-case scenario, he'll probably be a platoon power bat at first base/designated hitter wherever he ends up. Lowe's best season came in Texas in 2022, when he hit 27 homers and drove in 76 in 157 games.

The Atlanta Braves announced on Wednesday that they re-signed right-handed closer Raisel Iglesias to a one-year, $16 million deal for the 2026 season. The 35-year-old Cuban veteran will return to Atlanta for a fifth season, where he should be firmly locked in as their closer yet again. Iglesias didn't exactly look like himself early on, but it didn't take long for him to right the ship in 2025, and he finished with a 3.21 ERA (3.31 FIP), 0.99 WHIP, 29 saves, 73 strikeouts, and 16 walks in 67 1/3 innings out of the bullpen. He wasn't quite as good as he was in 2024, when he had a career-high-tying 34 saves and a career-best 1.95 ERA, but he did have an ERA of 1.96 with 51 K's and 12 walks after the start of June. Iglesias will be a little more volatile than most closers in 2026 because of his age, but his locked-in role on what should be a strong Braves team will make him a high-end closing target in fantasy.
