The Rangers have designated right-hander Dave Bush for assignment, according to Jeff Wilson of the Fort Worth Star-Telegram (via Twitter). The move will allow Texas to activate Tommy Hunter.
Bush, 31, made 14 relief appearances and three starts for the Rangers this season. In 2011, the right-hander posted a 5.79 ERA with 5.5 K/9 and 2.2 BB/9.
The Rangers signed Bush to a minor league deal with an invite to Spring Training in January. The veteran's deal ensured him a base of $1MM for making the team with up to $1MM in possible incentives.
