The Mariners added to their organizational relief pitching depth on their 40-man roster on Thursday, signing right-hander Ruben Alaniz to a free agent contract. It’s likely a split minor/major league contract given that Alaniz has never pitched in the big leagues.

Alaniz, 27, spent last season in the Rays’ minor league system. He pitched at multiple levels while dealing with two separate stints on the disabled list. He pitched in a total of 31 games, posting a 3-4 record with four saves and a 3.
