Chapman agreed to a one-year, $10.75 million contract with the Red Sox on Tuesday, Jeff Passan of ESPN.com reports.

Control continues to be a major issue for Chapman, who issued 39 free passes over 61.2 innings with the Pirates in 2024. However, he also struck out 98 batters and, even though he will turn 37 years old in February, he still ranked in the 98th percentile in fastball velocity this past season. With Kenley Jansen expected to depart in free agency, Chapman will be a candidate to close in Boston, along with Liam Hendriks and Justin Slaten.

The Mets signed Hartwig to a minor-league contract Monday that includes an invitation to spring training, Will Sammon of The Athletic reports.

Hartwig was recently non-tendered by the Mets but winds up remaining in the organization. Slated to turn 27 later this month, Hartwig missed a large portion of the 2024 season due to left meniscus surgery, although he returned late in the year. The righty reliever made 28 appearances for the Mets in 2023, collecting a 4.84 ERA and 30:15 K:BB over 35.1 frames.

Gillispie signed a one-year deal with Atlanta on Friday, Bob Nightengale of USA Today reports.

Gillispie spent most of the 2024 regular-season with Triple-A Columbus, and over 27 games (including 15 starts) he went 5-7 with a 4.05 ERA, 1.24 WHIP and 119:48 K:BB across 113.1 innings. He did make three appearances for the Guardians during the regular season, and across eight innings of work he allowed two runs on four hits and five walks while striking out eight batters. Gillispie will have an opportunity to carve out a role for himself either in Atlanta's starting rotation or out of the bullpen as a potential long-relief option.

The Cubs signed Kriske to a minor-league contract Tuesday, the pitcher announced on his X account.

Kriske, who turns 31 in February, spent the 2024 season at the Triple-A level split between the Yankees and Orioles organizations, holding a 3.39 ERA and 81:35 K:BB over 58.1 frames. The righty reliever has been roughed up in 20 major-league appearances, posting an 11.22 ERA and 25:17 K:BB across 21.2 innings.

The LG Twins of the Korea Baseball Organization re-signed Hernandez to a one-year, $1.3 million contract Wednesday, Jee-ho Yoo of the Yonhap News Agency reports.

Hernandez finished the 2024 season with the Twins, posting a 4.02 ERA over 47 regular-season innings before tossing 11 scoreless frames in the postseason. The 29-year-old holds a 5.10 ERA over 99 appearances (49 starts) at the big-league level.

The Tigers re-signed Vanasco to a minor-league contract Tuesday.

Vanasco was non-tendered by Detroit last week but returns to the organization on a minor-league pact. The right-hander spent most of the 2024 season at the Triple-A level, collecting a 2.45 ERA and 48:30 K:BB over 40.1 innings of work.

Atlanta re-signed Kerr (elbow) to a minor-league contract Tuesday.

Kerr was non-tendered by Atlanta last week but is back in the organization as he continues his recovery from Tommy John surgery. The left-hander is expected to miss most, if not all, of the 2025 season.

The Mariners are optimistic that Brash (elbow) can make his 2025 debut by the end of April, Adam Jude of the Seattle Times reports.

Brash had an internal brace procedure on his right elbow in early May, so a return in April would be aggressive. However, he's been working out at the team's spring training complex in Arizona and is considered ahead of schedule in his recovery. Brash was dynamite out of Seattle's bullpen in 2023, posting a 3.06 ERA and 107:29 K:BB across 70.2 innings. Once healthy, he will serve in a leverage relief role for the Mariners.

The Mets signed Cabrera to a minor-league contract Wednesday that includes an invitation to spring training, Will Sammon of The Athletic reports.

Cabrera, 28, compiled a 3.59 ERA, 1.47 WHIP and 50:29 K:BB over 62.2 innings with the Blue Jays in 2024. The left-handed reliever flashes plus stuff, but he's struggled with walks and inconsistency.

Rosenberg agreed to a contract with the KBO's Kiwoom Heroes on Monday, Dan Kurtz of MyKBO.net reports.

Rosenberg didn't find much success with the Angels during the 2024 campaign, posting a 6.00 ERA and 1.50 WHIP with a 17:8 K:BB across 24.0 innings. His KBO contract includes a $700,000 base salary with up to $100,000 in incentives, per Kurtz.
