The 2024 Boston Red Sox likely won't be a team that fans look back on often. Though the team broke the run of back-to-back last-place finishes in the AL East, they only finished in 3rd with an 81-81 record. There was a step forward from previous seasons, but some changes were made in the offseason that saw some players find new homes for 2025.
Boston retained ten of 14 hitters who played 50 or more games and nine of 14 who pitched more than 40 innings. We'll take a look at those nine players who have moved on to other pastures for 2025.
How are the members of the 2024 Red Sox performing with their new teams?
Tyler O'Neill
The Red Sox acquired Tyler O'Neill via trade in the offseason before 2024 from the Cardinals, going into the final year of his rookie contract. He had the second-best season of his career and entered free agency. The Orioles signed him to a three-year $49.5 million contract.
2025 hasn't been nearly as productive as last season was for O'Neill. He's only played in 24 games, finding himself on the 10-day IL twice so far. He's hitting just .188 with a .605 OPS. He has produced zero bWAR to this point. The signing has been heavily scrutinized due to his lack of production so far this season and his injury history, which is rearing its ugly head.
Dominic Smith
Dominic Smith was brought in during the 2024 season as a replacement for the injured Triston Casas. He quickly became a fan favorite in Boston, and he filled the vacancy at first base until the Red Sox designated him for assignment in late August.
After playing with Cincinnati down the stretch of 2024, he signed a minor league free-agent deal with the Yankees for 2025. After hitting .255 with a .781 OPS in Triple-A for the Yankees, Smith opted out of his minor league deal on June 1. He's since signed with the Giants and he's slashing .211/.227/.263 through six games.
Enmanuel Valdez
Enmanuel Valdez was acquired at the 2022 trade deadline with Wilyer Abreu for Christian Vázquez. He made his debut with the Red Sox in 2023, and in 2024 ,played the most games at second base for Boston. He was dealt to the Pirates over the offseason for minor league pitcher Joe Vogatsky, likely to free up a 40-man spot.
Valdez has played 31 games so far for Pittsburgh, but currently finds himself on the 60-day IL. He was hitting .209 with a .657 OPS and an 82 OPS+ before hitting the shelf. The Pirates have mostly played Valdez at first base this season, a position he didn't play for Boston.
Reese McGuire
Reese McGuire was brought in at the 2023 trade deadline from the Chicago White Sox. The Red Sox kept him around for 2024 to be the backup to Connor Wong. After he wasn't able to replicate his .667 OPS after being acquired in 2023 (.575 OPS in 2024), the Red Sox traded for Danny Jansen to replace him for the second half of 2024.
For 2025, he signed a minor league contract with the Cubs and was called up to the majors on May 25. He's played in seven games so far, batting .269 with an .807 OPS and two solo home runs.
Nick Pivetta
After being acquired at the 2020 trade deadline with Connor Seabold for Brandon Workman and Heath Hembree, Nick Pivetta became a staple in the Red Sox rotation. Pivetta's rookie contract ended after 2024, and the Red Sox offered him the qualifying offer (smartly), but no long-term extension. He signed a four-year contract with San Diego just before the start of 2025.
Pivetta has been very good for San Diego so far. In his first 13 starts, he's posted a 3.48 ERA, a 1.11 WHIP, and has dropped his HR/9 by almost one. He is coming off back-to-back bad outings though, allowing five runs to the Giants and then four runs to the Dodgers.The Canadian is looking like one of the steals of the offseason so far due to his contract being heavily backloaded (he's making just $2.5 million this season). He's already passed his bWAR total from 2024 (1.8 in 2025), and his ERA+ is over 30 points higher than his best season in Boston (113 in 2023).
Kenley Jansen
The future Hall of Fame closer signed a two-year contract with Boston prior to 2023. He posted back-to-back 25+ save seasons during his time there. Though he was vocal about his displeasure with the franchise's lack of win-now moves during his tenure, he solidly held down the ninth for two seasons for the Sox. Craig Breslow opted to let him walk at the end of his contract, and he signed a one-year deal with the Angels for 2025.
It has been a solid campaign for him in 2025. He posted eight scoreless outings in a row to start the season, and has only allowed runs in five of his 25 outings this season. He held the Red Sox scoreless in his appearances against them. The 37-year-old will likely be dealt in 2025 if the Angels fall out of the playoff race.
Chris Martin
Chris Martin signed a two-year contract with Boston before the 2023 season. He had a stellar 2023, allowing just six runs in 51.1 innings, and received a Cy Young vote. He couldn't repeat his performance in 2024 but was still serviceable, posting a 3.45 ERA with a 123 ERA+. He decided to head home to Texas for 2025 and signed a one-year deal with the Rangers for what some think will be his final season before retirement.
2025 has been a return to form for Martin. In 20.2 innings in relief, he has a 1.74 ERA, a 0.87 WHIP, and 24 strikeouts to just three walks. The 39-year-old is part of a Rangers pitching staff that is surprising a lot of fans this season and is keeping the Rangers in the playoff hunt. He is one of five pitchers (starter or reliever) that has a sub-2.50 ERA on their staff.
Cam Booser
Cam Booser was Boston's feel-good story of 2024. The then 32-year-old reliever made an incredible comeback to baseball, making his major league debut after years of injuries and a stint in independent baseball. He was a very solid second lefty for the Red Sox, and he posted a 3.38 ERA, 126 ERA+, and a 9.1 K/9. Despite the solid rookie season, the Red Sox dealt him to the White Sox over the offseason for a minor leaguer.
It's been an up-and-down season for the lefty. He has a 4.76 ERA in 22.2 innings for Chicago, and has allowed runs in seven of his 27 appearances, but has also had three multi-game stretches of allowing no runs. That included a seven-game stretch in April (four of which were against Boston) in which he only allowed one hit and struck out six. On a White Sox team that is already well out of the playoff race, Booser the second most appearances out of the pen so far and likely stays on the major league roster the entire season.
