The Tigers announced Tuesday that they’d invited 17 non-roster players to spring training, which begins with the first workout for pitchers and catchers on Feb. 20.

That number includes seven pitchers, most of whom will be in contention for any remaining open spots in the bullpen.

The Tigers signed lefty Omar Duran (25) and righties Rafael Dolis (27), Tim Melville (25) and Alberto Cabrera (26) to minor-league deals this offseason, while Luke Putkonen and Joe Mantiply are former draft picks. Lottery ticket free agent Joel Hanrahan is back for one more try, after he was unable to return to the mound last season, continuing his recovery from Tommy John surgery.

It also includes infielders Jordan Lennerton and Aaron Westlake, both of whom could make the squad as first basemen, should Miguel Cabrera’s ankle not allow him on the Opening Day roster. Jefry Marte (23) is a third baseman and 33-year-old Josh Wilson is a utility inielder who could replace the role once filled by fellow Mt. Lebanon, Penn., graduate Don Kelly, now with the Marlins.

Outfielder Xavier Avery, a former second-round pick of the Orioles, joined the Tigers on a minor-league deal this offseason, while outfielder Jason Krizan, a lefty-hitting former eighth-round pick of the Tigers, hit .293 last year at Double-A Erie.

There were also four catchers invited. Tigers signed catcher Miguel Gonzalez to a minor-league deal out of the White Sox system, and picked up catcher Manny Pina midseason last year.

Austin Green, a Tigers 13th-round pick in 2013, has yet to play about high-A ball, while the Tigers have high hopes and expectations for Grayson Greiner, their third-round pick in last year’s draft.
