It's a one-year, $1 million deal for the 36-year-old.

Coulombe had a dominant season with the Minnesota Twins last year before falling off for 15 innings with the Texas Rangers after the trade deadline. The veteran reliever induces critical, high-leverage outs with a soft-tossing repertoire.

In 31 innings with the Twins, he posted a 1.16 ERA with an 0.96 WHIP, with a 31:9 strikeout-to-walk ratio.

His control abandoned him in 15 innings with Texas later in the year.

On his career, across 11 seasons and 316 innings, Coulombe has compiled a 3.35 ERA, a 1.20 WHIP and five saves.
