Bryce Miller to the Giants? Inside the Trade That Could Land Rafael Devers in Seattle.

The Seattle Mariners have a problem most teams would kill for. They have too much good pitching.

Logan Gilbert, George Kirby, Luis Castillo, Bryan Woo, Emerson Hancock, and Bryce Miller all legitimately belong in a big-league rotation. Six guys for five spots. And that’s before Logan Evans returns from injury, or the two elite pitching prospects at Double-A — Kade Anderson and Ryan Sloan — force their way into the conversation. One of those guys could debut this year. Maybe both.

That surplus is why the Mariners are reportedly kicking the tires on one of the biggest bats available. According to ESPN’s Buster Olney, the San Francisco Giants are open to offers for their three highest-paid position players: Rafael Devers, Willy Adames, and Matt Chapman. Also listed as available: Luis Arraez and Robbie Ray.

The fit with Seattle isn’t hard to see.

Devers would be the headline. A left-handed power bat who can play first base or DH, he’d slot into the middle of a Mariners lineup that’s been boom-or-bust so far. Young guys are exciting until they go cold for a week. Devers adds the kind of consistent thump that wins division games in August.

Chapman would also make sense as a Gold Glove third baseman, but the real prize is Devers. And the asking price will start with an arm.

Bryce Miller’s resurgence changes the math

Miller has been excellent since coming off the IL. The 27-year-old is 3-2 with a 1.97 ERA and 1.9 WAR over seven starts. After a rough 2025 that was largely derailed by a left oblique injury, he looks like the pitcher who broke out in 2024 (12-8, 3.4 WAR over 31 starts).

The Giants would plug him right into their rotation. For a franchise that’s been searching for reliable starting pitching, Miller is the kind of ready-made arm that accelerates a rebuild without requiring two years of development.

But Seattle won’t stop there. To land Devers, the Mariners would likely need to include more than just Miller.

What a real package looks like

Outfielders Lazaro Montes, Yorger Bautista, and Jonny Farmelo are the kind of lottery tickets the Giants would want. Versatile infielder Ryan Bliss and shortstop prospect Felnin Celesten also fit. And if Seattle is willing to include a reliever — say, the injured Matt Brash, who could eventually transition back to starting, or veteran Gabe Speier — that could seal it.

A realistic opening offer: Miller, Farmelo, Bliss, and Brash. If the Mariners take on the entirety of Devers’ massive contract, that package might be enough.

The Giants would be getting a controlled starter, a power-armed reliever with upside, and two position players with big-league ceilings. Seattle gets a proven middle-of-the-order bat to run with their elite rotation.

There’s no guarantee this happens. But the foundation is there. And in the AL West, where a half-game separates first from second, a move like this could decide the division.
