RHP Mason Tobin assigned outright to Round Rock

Arlington, Texas - The Texas Rangers announced today that right-handed pitcher Mason Tobin has been assigned outright to Triple-A Round Rock of the Pacific Coast League.

Tobin opened the 2011 season with the Rangers and made four relief appearances in the first major league action of his career. He had no record and a 6.75 ERA (5.1 IP/5 H/5 R/4 ER/5 BB/0 SO). The right-hander made his major league debut on April 2 versus Boston and his final appearance on April 19 against the Los Angeles Angels.

Tobin was placed on the 60-day disabled list on April 20. He missed the remainder of the season while undergoing right elbow ligament reconstruction surgery, which was performed by Dr. James Andrews on June 1 in Birmingham, Alabama.

He had appeared in just 25 professional career games, all in the Angels organization, prior to 2011, missing all of 2010 after right elbow surgery. Tobin was selected by the Chicago Cubs in Major League Rule 5 Draft and then traded to Texas for cash considerations on December 9, 2010.

With today's transaction, Texas has 31 players on its Major League roster.

In addition, the club announced that the five players offered outright assignment on Wednesday, RHP Omar Beltre, INF Andres Blanco, INF Esteban German, RHP Eric Hurley, and RHP Merkin Valdez, have all been granted free agency.
