The full list of Mariners’ non-roster invitees

Veteran second baseman Adam Kennedy is the 15th player signed to a Minor League contract with an invitation to Spring Training by the Mariners, who usually bring in 15-20 candidates each year that way in the hope of adding depth and competition.

Last year’s group included infielder Josh Wilson and Chris Woodward, catchers Josh Bard, Guillermo Quiroz and Eliezer Alfonzo, relievers Chad Cordero and Chris Seddon and starter David Pauley, who all wound up playing various roles with the Major League club at some point.

In 2009, the non-roster invitee list yielded DH Mike Sweeney, reliever Chris Jakubauskas and catcher Jamie Burke, among others.

Of course, there are always a number of Minor League signees who don’t make it either. But it is a good way to find a few hidden — and inexpensive — gems and here is the list of non-roster signees landed so far this offseason by Jack Zduriencik and his crew.

Pitchers enny Bautista, Royce Ring, Charlie Haeger, Fabio Castro, Chris Smith, Justin Miller, Chris Seddon, Yusmeiro Petit

Catchers: Josh Bard, Chris Gimenez.

Infielders: Adam Kennedy, Luis Rodriguez, Sean Kazmar

Outfielders: Ryan Langerhans, Mike Wilson.

They’ll report with the rest of the Mariners next month in Peoria and it’s likely that a couple will wind up finding some role with the club this coming season.
