The Mariners have two years of team control on Logan Gilbert, three years on George Kirby, four years each on Bryce Miller and Bryan Woo, and two years with a vesting option for a third year on Luis Castillo.
Starters Kade Anderson and Ryan Sloan are among seven Seattle prospects on Jim Bowden's Top 50 prospect list.
The Mariners may well make a push to sign first baseman Josh Naylor. However, Seattle returns lefthand-hitting 1B/OF Luke Raley, who in 2023-24 posted 5.9 bWAR to Naylor's 3.7 bWAR over the same two seasons. Recency bias clearly favors Naylor, who is three years younger than Raley.
