The Boston Red Sox have agreed to a contract extension with outfielder Ceddanne Rafaela, according to reports.

Rafaela, who has appeared in just 38 Major League games, receives an eight-year, $50 million deal. Pending a physical, he'll be tied to the Red Sox through the 2031 season.

Rafaela won the starting job in center field in spring training but can also play shortstop.

With injuries and bad weather draining their rotation already, the New York Mets have agreed to a contract with veteran starter Julio Teheran, according to multiple reports.

Teheran, a longtime Mets nemesis with rival Atlanta, spent spring training with Baltimore. The right-hander opted out of his minor league deal with the Orioles late last month when he didn't make their Opening Day major league roster.

The New York Post was first to report the deal between the Mets and Teheran.

The Chicago White Sox and right-hander Mike Clevinger have agreed to a one-year deal, a source told ESPN, confirming multiple reports.

Clevinger, 33, is 60-39 with a 3.45 ERA in 788 innings across seven seasons in the big leagues, including a 9-9 stint with the White Sox last season.

Catcher Will Smith and the Dodgers agreed to a 10-year, $140 million contract extension, it was announced Wednesday, the latest deal in an offseason of massive spending by a Los Angeles team that is locking up its core members.

Smith, who turns 29 on Friday, was due to hit free agency following the 2025 season. Los Angeles prevented that by giving him a deal that will run through the 2033 season and keep him in the middle of one of baseball's most dangerous lineups.

Left-hander Jordan Montgomery and the Arizona Diamondbacks are in agreement on a one-year, $25 million contract that includes a vesting player option for a second season, sources told ESPN on Tuesday night, bolstering the National League champions' rotation with the postseason standout from the team that beat them in the World Series.

The deal, which is pending a physical, ends Montgomery's free agency two days before Opening Day and could include a second-year player option at $20 million if Montgomery makes 10 starts. The option would be for $22.5 million if Montgomery reaches 18 starts and $25 million at 23 starts, sources said.

Right-hander Chase Anderson agreed Sunday to a one-year contract with the Boston Red Sox, one day after he was released from a minor league deal by the Pittsburgh Pirates.

Anderson, 36, was 1-6 with a 5.75 ERA last year in 17 starts and two relief appearances for Tampa Bay and Colorado.

The New York Mets and designated hitter J.D. Martinez are in agreement on a one-year, $12 million contract, a source confirmed to ESPN on Thursday. The deal is pending a physical.

Martinez gives the Mets' lineup a proven power source behind slugger Pete Alonso one week before Opening Day. 

The Texas Rangers have reached an agreement on a one-year, $4.5 million deal with Michael Lorenzen, according to a source.

The contract could be worth up to $7 million with incentives.

After going 5-7 with a 3.58 ERA and making the All-Star Game with the Detroit Tigers, the right-hander was dealt to the Philadelphia Phillies at the trade deadline.

Blake Snell's lengthy free agency reached a conclusion Monday night.

The reigning National League Cy Young winner agreed to a deal with the San Francisco Giants, a source told ESPN's Jeff Passan, confirming a report by the New York Post.

The agreement is for two years and $62 million and includes an opt-out after the first season, the source told ESPN.

The Pittsburgh Pirates are bringing in veteran outfielder Michael Taylor on a one-year deal worth $4 million, sources told ESPN's Jeff Passan on Friday.

The deal is pending a physical.

Taylor, who turns 33 this month, joins a team that is looking for help in right field as the season approaches. He hit .220 with 21 home runs and 51 RBIs last season while playing in Minnesota.
