The Rangers will release Ryan Tucker to create 40-man roster space for Mark Hamburger, according to Anthony Andro of the Fort Worth Star-Telegram (on Twitter). Tucker, 24, had not been on the Rangers' active roster before they made the move.
Tucker appeared in five games for the Rangers this year, but spent most of his season at Triple-A Round Rock. The right-hander posted a 5.40 ERA with 8.4 K/9 and 4.1 BB/9 in 68 1/3 innings at Triple-A before getting released. The Rangers claimed Tucker, a first round pick in 2005, off of waivers from the Marlins last October.
