The Mariners added another veteran reliever to their big-league camp roster for spring training by signing right-hander Jean Machi to a minor-league deal.
Machi, 34, is 12-2 with a 3.47 ERA in 189 games over four seasons for San Francisco and Boston. His best season was 2014, when he was 7-1 for the Giants with a 2.58 ERA in 71 games.
He spent last season pitching in the minors, where he was a combined 4-3 with a 3.65 ERA in 48 games at Triple-A Iowa (Cubs) and Sacramento (Giants).
