SEATTLE — The post-Rafael Devers Era has begun.

The Red Sox and Mariners will play here at T-Mobile Park on Monday at 9:40 p.m. eastern.

Rookie Kristian Campbell, who has struggled defensively at second base, will serve as the DH.

Devers started Boston’s first 73 at DH. So this marks the first time this season that anyone else will be in that spot.

Devers was sent to the San Francisco Giants in a shocking blockbuster trade Sunday in exchange for pitchers Jordan Hicks and Kyle Harrison as well as prospects James Tibbs III and Jose Bello.

David Hamilton will play second base. Rookie right fielder Roman Anthony will serve as the No. 3 hitter.

First baseman Abraham Toro will take Devers’ regular spot as the No. 2 hitter.

Nate Eaton is en route from Triple A to Seattle to take Devers’ spot on the roster. Eaton has made starts at all three outfield positions, second base, third base and shortstop.

Red Sox righty Lucas Giolito (2-1, 5.45 ERA) will start opposite Seattle right-hander Logan Gilbert (1-1, 2.37 ERA).
