The Tigers have announced a minor-league deal with lefty Hector Santiago. He’ll receive an invitation to participate in MLB Spring Training.

Santiago had some rather productive campaigns earlier in his career. But at 32 years of age, he has settled into the existence of a journeying southpaw swingman.

Over the past three years, Santiago has transitioned from membership in a 5-man rotation to long relief duties. He carries only a 5.20 ERA in the 206 innings he has thrown during that span. Santiago has struck out 8.5 batters per nine over that time but has also handed out excessive numbers of walks (4.9 per nine) and home runs (1.7).

It’s tough to imagine Santiago having much of a shot at the Detroit rotation in camp. But he could challenge for a bullpen role or otherwise slot into the Triple-A staff to provide depth.
