Arencibia was the Rangers Opening Day catcher, but eventually lost his job to Robinson Chirinos. He was sent to Triple-A on May 21 and brought back after the All-Star break, but primarily as a first baseman.
The Rangers also outrighted pitchers Pedro Figueroa and Wilmer Font, outfielder Engel Beltre and infielder Guilder Rodriguez to Round Rock. The moves leave the Rangers with 37 players on the 40-man roster.
Ortiz missed most of the season with a fractured left foot. He was 2-2 with a 4.23 ERA in 32 games for the Rangers in 2013 but did not pitch in the Majors this past season.
