The Seattle Mariners signed right-hander Ryan Cook to a one-year contract on Thursday.
The 28-year-old Cook has made 208 relief appearances in four major league seasons. His best year came in 2012 when he posted a 6-2 record with a 2.09 ERA in 71 outings and was named to the American League All-Star team.
Last year, Cook pitched a combined nine games for the Oakland Athletics and the Boston Red Sox and gave up 18 earned runs for a 18.69 ERA. With Triple-A Nashville and Pawtucket, Cook logged a 4-1 record with a 3.16 ERA in 37 appearances.
"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."
Froom 2011 to 2014, Cook fashioned a 2.60 ERA, which was eighth best in the American League during that span.
