The Seattle Mariners are keeping their hard-throwing closer. The team exercised a $9 million option on reliever Andrés Muñoz on Thursday, which keeps him from becoming a free agent.

Seattle went the other way on two other players. It declined a $9 million option on outfielder Victor Robles and a $6,075,000 option on right-hander Bryce Miller.

Robles gets a $500,000 buyout and is now a free agent. Miller gets a $15,000 buyout but stays under team control and is eligible for salary arbitration.

A tougher year for Muñoz

Muñoz is 27 and was an All-Star in 2024 and 2025. This season was a step back. He went 5-6 with a career-worst 4.24 ERA and 28 saves in 38 chances. He struck out 89 batters in 57 1/3 innings.

His contract also gives Seattle a $10 million option for 2028. That figure can rise based on how many games he finishes.

Injuries slowed Robles and Miller

Robles is 29. He hit .256 with no homers, nine RBIs and 10 stolen bases in 65 games. A right pectoral strain kept him out from April 6 to May 22. He played only 32 games in 2025 after dislocating his left shoulder.

Miller is 28. He went 4-10 with a 4.17 ERA in 21 starts and one relief appearance. A strained left oblique delayed his season debut until May 13.

Four Mariners hit the market

Outfielders Randy Arozarena and Taylor Ward, shortstop J.P. Crawford and left-hander Hoby Milner all became free agents on Thursday. Seattle now has several big holes to fill this winter.
