Farm system

Four of the five first-year players who have seen action with the Mariners in 2023 are still on the active roster as this is written, so there’s hope for the Dipoto Class of 2023. But it’s a safe bet that there are no Julio Rodriguez types in this class.

The only position player who graduated from the Mariners system this year is infielder Joe Caballero. Called up in April, he’s been in 52 games with a .242 average. But he’s also shown some power and enough baserunning savvy to steal 11 in 13 tries. All of that leaves his WAA at an impressive +1.1.

Bryce Miller is a rotation starter called up in early May and given 11 starts since then. He’s held his own, producing a 5-3 record and 3.97 ERA in 59 innings, good for a +0.2 WAA.

Ty Adcock is a bullpen filler piece off to a spectacular start. Called up from Arkansas in mid-June, Adcock hasn’t allowed a run or walked a batter in seven appearances encompassing nine innings. It would be hard to do much better than that.

Dylan Woo, a starter, got the call in early June and has a 4.37 ERA in 23 innings across five starts.

Darren McCaughan has been up and down twice this spring, and is presently sentenced to the IL with an arm injury.
