The Mariners have made one of the biggest rotation pickups of the offseason already, signing Robbie Ray to a five-year, $115MM guarantee shortly before the lockout. Even after landing the reigning AL Cy Young award winner, Seattle is expected to pursue additional rotation help whenever the transactions freeze is lifted, writes Corey Brock of the Athletic.

The group behind Ray already looks pretty solid. Chris Flexen had a nice 2021 campaign in his return from a stint in South Korea. Marco Gonzales had some uncharacteristic home run struggles this past season, but he’s a reliable mid-rotation arm. Logan Gilbert posted a 4.68 ERA as a rookie, but his peripherals were more impressive and he’s one of the most highly-regarded young arms around the league.

A top four of Ray, Flexen, Gonzales and Gilbert is a solid start, and it seems there’s only one season-opening spot left up for grabs. While the Mariners ran a six-man rotation at points last season, president of baseball operations Jerry Dipoto suggested earlier this offseason that’s not the plan in 2022. Dipoto noted that last season’s six-man starting staff was primarily a function of the club’s concern about a drastic pitcher workload spike on the heels of a 60-game schedule in 2020. “Now that we are a full season removed from the truncated 2020 season, we feel the five-man rotation is a perfectly reasonable way to go,” Dipoto said (via Brock).
