SEATTLE -- The Rangers have called up left-handed reliever Alex Claudio from Triple-A Round Rock and sent down right-hander Phil Klein.
Texas is still going with an eight-man bullpen.
Claudio had pitched two scoreless innings at Round Rock in his only appearance. He had a 2.87 ERA in 18 appearances with the Rangers last season. Klein, who is expected to start at Round Rock, had retired all nine batters he faced in two games with the Rangers.
