Moniak (ankle) heads out on rehab assignment

Mayer was viewed as one of Boston’s potential future franchise cornerstones just a few years previously. He simply never found his footing at the highest level despite possessing impressive raw talent and a sweet-looking left-handed swing. The 23-year-old former fourth overall selection from the 2021 draft has struggled to stay healthy at the highest level and the Red Sox ultimately decided to move on, using him as a trade chip to fortify their bullpen. The meteoric rise of Franklin Arias, who has emerged as the club’s potential shortstop of the future, seemingly sealed Mayer’s fate here. It’s a decent move for his long-term future as he’ll get a change of scenery and plenty of opportunities to emerge as a key contributor in San Francisco.

Ramos makes a ton of sense for the Yankees as a temporary stopgap while both Aaron Judge (rib) and Cody Bellinger (hamstring) are on the injured list, but he could wind up getting squeezed into a platoon role once they’re back. The 26-year-old corner outfielder has just nine round-trippers in 74 games this season after reaching the 20-homer plateau in each of the previous two years. He should benefit from leaving Oracle Park’s pitcher-friendly dimensions behind in favor of Yankee Stadium.

Hartle was previous acquired by the Guardians in the 2024 deal that sent the Pirates Spencer Horwitz. The 6-foot-6 southpaw has forged a 3.86 ERA over 19 starts with Double-A Akron while posting a K/BB ratio of 88/37 in 93 1/3 innings. The southpaw projects as a backend starter at the next level, but Washington will hope to untap more from a player that doesn’t turn 24 until the end of March.

It’s not a bad return for San Francisco as they pivot towards more of a long-tern rebuilding project. Lalane was one of the hottest pitching prospects in baseball last month as he’s looked like an impactful starter again following a couple injury-marred seasons. He’s a worthwhile gamble for the Giants considering how starved they are for pitching in the minors.

Dion has been an up-and-down arm for the Guardians, but the 26-year-old will likely get an opportunity to be a mainstay with the Nationals to try and help one of the worst bullpens in baseball. That won’t make him fantasy relevant, but National fans would just appreciate some competence in the middle innings.

Griffin has been outstanding in his return to MLB action with a 3.06 ERA and 116/30 K/BB across 129 1/3 innings, but the Nationals will aim to sell high and move the southpaw. The Guardians will hope he can keep it up, and fantasy managers who play in AL-only leagues should be looking to take a flyer on Griffin for the remainder of 2026. There’s some risk here, but there’s a decent enough sample of quality hurling to believe he can be an effective option for the final two months.

Wells bolsters Tampa Bay’s relief depth heading into the home stretch after thriving as a full-time reliever with the division-rival Orioles this season, posting a solid 2.67 ERA across 54 innings of work. He’s an interesting pickup for the Rays, who have had plenty of success with turning unheralded names into elite relievers in the recent past.

Forret heads back to Baltimore after being sent to Tampa Bay a couple months earlier in the Shane Baz trade. Clearly, the Orioles felt comfortable bringing him back in exchange for Well, who has found success since converting to a full-time reliever.
