Veteran pitcher Jose Contreras was offered re-assignment to minor league camp, part of a flurry of roster moves the team made on Monday.
Contreras, 42, is weighing his options, which could include retiring.
Pitchers Nick Tepesch, Cory Burns and Miles Mikolas along with infielder Andy Parrino were optioned to Triple-A. Pitcher Daniel Bard, recovering from thoracic outlet syndrome surgery in January, was re-assigned to minor league camp along with outfielders Brad Snyder and Bryan Peterson, catchers Patrick Cantwell and Brett Nicholas and infielder Kensuke Tanaka.
The Rangers now have 30 players remaining in big-league camp.
