The Mariners already completed one trade today, sending Robbie Ray to the Giants in exchange for Mitch Haniger, Anthony DeSclafani and cash considerations, and have now completed a second. They are sending infielder José Caballero to the Rays in exchange for outfielder Luke Raley, per announcements from both clubs.
“We’re thrilled to add Luke Raley to the middle of our lineup as a left-handed bat with positional versatility,” Mariners general manager Justin Hollander said in that club’s press release. “Offensively, Luke brings power paired with game-changing baserunning and instincts. He’s also a solid defender across multiple positions, adding further flexibility to our lineup on a nightly basis.”
Raley, now 29, was drafted by the Dodgers and made a brief major league debut with them in 2021. He was traded to the Rays and then got some more limited MLB time in 2022. He finally got his first extended stretch of time in the big leagues last year and ran with it. He took 406 plate appearances over 118 games in 2023, striking out at a 31.5% clip but also hitting 19 home runs. His overall batting line of .249/.333/.490 translated to a wRC+ of 130, indicating he was 30% better than league average. He also stole 14 bases in 17 tries and received solid grades for his outfield defense while also spending a bit of time at first base.
Despite that strong performance, Raley was part of a crowded outfield mix that also featured Randy Arozarena, Josh Lowe and José Siri in regular roles. Yandy Díaz is set to likely be the everyday first baseman, while players like Harold Ramírez, Jonathan Aranda, Jonny DeLuca and others were in the mix for playing time as well. With Raley now out of options, he needed to be kept on the active roster or else be removed from the 40-man entirely.
In Seattle, the path to playing time should be more smooth. That club let Teoscar Hernández reach free agency without making him a qualifying offer and also traded Jarred Kelenic to Atlanta. They have since added Mitch Garver to be their primary designated hitter, and take a share of the catching time from Cal Raleigh, while Haniger was acquired earlier today to join the corner outfield mix.
Julio Rodríguez is entrenched in center but Raley and Haniger could perhaps take the corner regularly, with players like Cade Marlowe, Taylor Trammell and Dominic Canzone also a part of that corner outfield picture. At first base, Ty France has been the regular in Seattle for the past three years but his production dipped in 2023. If that continues into this year, Raley gives them a fallback option for that position.
The Rays mostly shielded Raley from left-handed pitchers, with 363 of his 406 plate appearances coming with the platoon advantage last year. His high strikeout rate also doesn’t mesh with Seattle’s stated intention to cut down in that department, but the power, speed and defense make him enticing nonetheless. He’s also still at least a year away from reaching arbitration, meaning he fits well on a club with financial concerns like the Mariners. He can be controlled for another five seasons before qualifying for free agency.
Caballero, 27, made his major league debut with the Mariners last year, getting into 104 games. He hit .221/.343/.320 in his 280 plate appearances, drawing a walk in 10% of them. That production amounted to a wRC+ of 96, indicating he was just 4% below league average. But he also stole 26 bases in 29 tries and received strong grades for his defense at the two middle infield positions, as well as spending small amounts of time at third base and left field.
The ability to play shortstop likely appeals to the Rays, who have plenty of uncertainty there. Wander Franco once seemed to be firmly entrenched in that position, having signed an 11-year extension going into the 2022 season. But he is currently under investigation for allegedly having inappropriate relationships with minors and it’s unknown when, if ever, he will play a Major League Baseball game again.
Assuming Franco isn’t an option in 2024, the Rays have guys like Taylor Walls, Junior Caminero and Osleivis Basabe as potential shortstops on the roster. However, none of that trio is a lock to hold down the job this year. Walls and Basabe are broadly considered strong defenders but weaker at the plate while Caminero is generally considered the opposite. Basabe and Caminero both have less than 100 major league plate appearances.
Caballero’s first taste of MLB action was subpar, but only slightly so. He’s always hit well in the minors, perhaps leaving some room for him to continue developing with more exposure to major league pitching. He still has a full slate of options and less than a year of service time, meaning he can be a long-term part of the Rays’ roster if things click.
Ken Rosenthal of The Athletic first reported the framework of the deal while Jeff Passan of ESPN first relayed that it had been completed.
