Rangers purchase contract of big righty Klein

The Rangers purchased the contract on Friday of towering right-hander Phil Klein from Triple-A Round Rock. In a corresponding move, the club designated left-hander Ryan Feierabend for assignment.

Klein, who checks in at 6-foot-7 and 260 pounds, has been dominating the Minor Leagues this season and for much of his professional career.

He's thrown 35 consecutive scoreless innings between Double-A Frisco and Round Rock and is 3-0 overall with a 0.52 ERA in 33 outings. Since his June 25 promotion to Round Rock, Klein has tossed 18 1/3 scoreless innings while racking up 28 strikeouts -- good for an average of 13.7 strikeouts per nine innings.

A 30th-round selection in the 2011 First-Year Player Draft, Klein has breezed through the opposition to this point in his career. Since making his professional debut in 2011, Klein has tallied a 16-3 record to go along with a 1.87 ERA over 121 appearances, all but two of which have come out of the bullpen.

As for Feierabend, the southpaw posted a 6.14 ERA over six appearances (7 1/3 innings) with the Rangers after his July 12 promotion.
