The Rays made a move to bolster their bullpen depth on Monday by signing reliever Scott Dohmann, a 28-year-old righthander, to a one-year deal.

Dohmann pitched in 48 games last season, going 2-4 with one save and a 7.08 ERA. He started the season with the Rockies, was sent to Triple-A, then traded to the Royals on July 31 and nontendered after the season.

The Rays had space on their 40-man roster by releasing injured reliever Shinji Mori, who on Monday agreed to a minor-league contract. He is working his way back from a shoulder injury that forced him to miss all of last season.
