The Mariners made a pair of moves on Thursday involving relievers.
Ryan Cook was signed to a one-year deal by the Mariners shortly after the team released Anthony Bass.
Cook, 28, shared time between the Athletics and Red Sox last season spending much of the year in the minors after posting a 2.77 ERA for the Athletics between 2011-14.
“We’re looking forward to seeing Ryan in a Mariners uniform,” Mariners general manager Jerry Dipoto said. “He remains just 28 years old and is just one season removed from being one of the more effective setup relievers in the American League.
“His presence enhances both our bullpen depth and overall upside.”
Cook’s non-guaranteed deal is worth $1.1 million with another $300,000 available in performance bonuses based on games pitched.
The Mariners released Bass on Thursday so that the reliever could pursue an opportunity to pitch in Japan. He had been acquired by the Mariners in a Nov. 16 trade with the Rangers with outfielder Leonys Martin which saw reliever Tom Wilhelmsen, outfielder James Jones and utilityman Pat Kivlehan head to Texas.
In 33 relief appearances last season Bass did not record a decision while compiling a 4.50 ERA and 1.34 WHIP. He would have went to spring training competing for a spot in the Mariners bullpen.
