The reshaped Mariners bullpen will have plenty of new faces and new roles. But the latest addition could fill the all-important closing job for the 2016 season.

Baseball sources confirmed Saturday that the Mariners have agreed to a two-year, $10 million contract with former Miami Marlins closer Steve Cishek.

An announcement of the signing likely will come Monday morning. Cishek was in Seattle on Thursday and Friday taking a physical. He will earn $4 million in 2016 and $6 million in 2017 with $7 million in possible incentives. Cishek was scheduled to make about $7 million for 2016 in arbitration and was arbitration-eligible for next season. The Mariners bought out those years with the contract.

On Thursday as the winter meetings came to a close, Mariners general manager Jerry Dipoto said they would add at least one more reliever on a major-league free-agent deal. That reliever was the side-arming Cishek, who will compete with veteran Joaquin Benoit for the closing duties.

Ideally, the Mariners hope Cishek, 29, can bounce back to his closing form of 2013-14 so they can Benoit as the setup man in the eighth inning. Over that two-year span, Cishek saved 73 games for the Marlins. He pitched 135 innings during that span, posting a 2.73 ERA with 158 strikeouts and 43 walks.

Much like his Marlins team last season, Cishek struggled early. In his first 19 outings of 2015 he posted a 1-5 record with four saves and a 6.58 ERA. Over his next 40 appearances, during which he was traded to the St. Louis Cardinals, Cishek posted a 1.75 ERA in 36 inning as a setup man.

The Mariners will have to make a corresponding roster move and remove a player off the 40-man roster. Dipoto also plans to more relievers to minor-league contracts with spring-training invites.
