The Boston Red Sox and right-hander Corey Kluber agreed to a one-year contract with a team option for the 2024 season, sources told ESPN's Jeff Passan.
The pact will guarantee Kluber $10 million in 2023, a source told Alex Speier of the Boston Globe.
Kluber spent the 2022 season with the Tampa Bay Rays. The 36-year-old posted a 10-10 record with a 4.34 ERA, 3.57 FIP, and 7.63 K/9 across 164 innings (31 starts).
Kluber will replace Nathan Eovaldi, who signed a two-year contract with the Texas Rangers on Tuesday.
The two-time Cy Young winner joins his third AL East team in as many seasons. Kluber spent the 2021 campaign as a member of the New York Yankees.
The Red Sox are projected to enter 2023 with Chris Sale, Nick Pivetta, Garrett Whitlock, and James Paxton alongside Kluber in the rotation.
