The Mariners are set to give Kade Anderson his first shot in the majors.
Seattle plans to promote the pitching prospect for a Saturday start against the Cubs, according to Jeff Passan of ESPN. The move will require the club to clear room on the active roster by taking a pitcher off it, and Seattle also has to create a 40-man opening.
That can be handled by moving Matt Brash to the 60-day injured list, which would not change his return timetable. Brash has already been out more than 60 days because of a lat strain.
Jerry Dipoto had already hinted that Anderson was getting close. Earlier this month, the Mariners president of baseball operations said the club would wait for a rotation opening before bringing him up.
“We’re not going to put Kade in the bullpen. He’s the best starting pitcher in the minor leagues,” Dipoto said in early August (link via Daniel Kramer of MLB.com).
He also described Anderson as “the next starter up” behind Seattle’s front five after the team traded Luis Castillo to the White Sox.
The promotion appears to line up with another six-man rotation in Seattle. The Mariners are not currently managing any injuries among their top five starters, but George Kirby and Bryce Miller have both been hit hard this month. If Seattle wanted to stay on a five-man schedule, it could move one of them to the bullpen, though that would come as a surprise considering both pitchers’ track records.

Mariners Suddenly Have A Tough Bench Decision Waiting
Brock Rodden has given the Mariners something worth noticing in a very small sample, and he has done it in the kind of way that tends to stick with a bench coach. In six big league games, the rookie has hit .300, piled up three extra-base hits and shown the kind of defensive flexibility that makes a reserve infielder easier to carry on a roster that is always trying to squeeze value out of every spot.
The timing only sharpens the question, because Seattle is headed toward the return of J.P. Crawford from injury, which will force the club to sort out its reserve infield picture. Rodden has been more productive at the plate than Leo Rivas this season, and that creates a real choice rather than a simple numbers move, with the Mariners now weighing whether the hot hand and the versatility are enough to keep him around once Crawford is back.

Mariners Finally Make A Prospect Move Fans Have Been Waiting For
The Mariners are bringing Kade Anderson into the big-league picture at a time when every move still feels tied to the postseason race. Seattle has spent much of the season trying to stay within reach in the wild-card hunt, and calling up a top pitching prospect who has carved up Double A is the sort of aggressive decision that signals the front office is still looking for help anywhere it can find it.
Anderson, the No. 3 overall pick in the 2025 draft, has backed up the hype with the kind of minor league production that made his promotion feel overdue. The next step is a significant one, though, because his first major-league start will come with the Mariners still below .500 and in a spot where every outing can tilt the mood around the roster.

Mariners Are About To Face A Tough Roster Crunch
J.P. Crawford, Carlos Vargas and Matt Brash are all moving closer to rejoining the Mariners, and the timing could make life interesting for Seattles front office. Crawford has been down in Triple-A, Vargas has been pitching there after his stint on the 60-day injured list, and Brash is working through bullpen sessions as he pushes toward a late-August or early-September return. For a club trying to stay balanced in the infield and the bullpen, those are three notable reinforcements arriving on similar timelines.
The complication is obvious: good players coming back usually mean somebody else has to move. Seattle will have to sort out the roster when those returns come due, and the choices could touch both everyday roles and relief depth. The Mariners are getting healthier at the right time, but the next step may be less about who is returning and more about who gets squeezed out to make room. [Read more 🡒]
