The Seattle Mariners are reportedly set to acquire outfielder/first baseman Luke Raley from the Tampa Bay Rays in exchange for infielder Jose Caballero. The potential deal follows up on a blockbuster trade in which Seattle sent former Cy Young winner Robbie Ray to the San Francisco Giants in exchange for outfielder Mitch Haniger and right-hander Anthony DeSclafani. Raley enjoyed a big season for the Rays in 2023, hitting .249 alongside 19 home runs, 14 stolen bases, and an .823 OPS across 406 plate appearances. His big-time production was good for 30% above the league average, as per his 130 wRC+, while his underlying data backed up his work. Caballero, 27, hit .221 with four home runs and a hefty 26 stolen bases across 104 appearances last season.

Right-hander Anthony DeSclafani is headed to the Seattle Mariners in a blockbuster trade that will see former Cy Young winner Robbie Ray heading to the San Francisco Giants while outfielder Mitch Haniger joins DeSclafani in heading to Seattle, joining his former club in the process. DeSclafani has spent the past three seasons in the Bay Area but injuries limited him to just 24 starts over the last two seasons after he posted a 3.17 ERA across 31 starts in his debut season with the Giants. The righty posted a 4.88 ERA in 19 starts in the 2023 season but an elbow injury cut his season short. In parts of nine big-league seasons, the 33-year-old owns a solid 4.20 ERA between the Marlins, Reds, and Giants.

Outfielder Mitch Haniger is headed back to the Seattle Mariners in a trade with the San Francisco Giants that sends former Cy Young winner Robbie Ray to San Francisco while right-hander Anthony DeSclafani joins Haniger in heading to the Mariners. The veteran spent five seasons in Seattle before joining the Giants in free agency prior to the 2023 season. He once again had trouble staying on the field in his lone season in the Bay Area as he hit just .209 with six home runs across just 229 trips to the plate. A myriad of ailments have plagued the 33-year-old in his career as he's played in more than 96 games just twice in seven seasons. He will presumably take the spot of free agent outfielder Teoscar Hernandez in Seattle while the club also traded outfielder Jarred Kelenic to the Braves this winter.

The Seattle Mariners and San Francisco Giants connected for a blockbuster trade on Friday as Seattle will send former Cy Young winner Robbie Ray to the Giants in exchange for former Mariners outfielder Mitch Haniger and right-hander Anthony DeSclafani. Ray, the 2021 AL Cy Young winner with the Toronto Blue Jays, went on to sign a five-year, $115 million deal with the Mariners in free agency prior to the 2022 season. While he regressed some, Ray still posted a 3.71 ERA and excellent 19.4% K-BB% across 32 starts that season. However, he was limited to just a single start in 2023 due to an elbow injury. Subsequent Tommy John surgery will sideline him until after the All-Star break. A big-time strikeout pitcher, the 32-year-old has reined in the free passes that plagued him earlier in his career as he looks to bounce back with the Giants in the 2024 campaign.

The Detroit Tigers have signed relief pitcher Andrew Vasquez to a minor-league contract. The club claimed the southpaw from the Phillies after he was designated for assignment mid-season in 2023. Vasquez had worked to a 2.27 ERA with the Phillies but his underlying metrics suggested regression was on the horizon. That was indeed the case as the 30-year-old struggled to an 8.31 ERA across 12 outings with the Tigers. He did fare much better with a dynamite 1.35 ERA at Triple-A Toledo but that figure came in a small seven-appearance sample size. Nonetheless, he should get a decent shot as a left-handed option in the Tigers bullpen at some point in the 2024 campaign.
