ST. LOUIS (KMOX) - The Cardinals have a new left-handed pitcher in their system.

The club announced Saturday that it landed John Gaub on a waiver claim from the Texas Rangers.

The 27-year-old will begin his Redbirds career at AAA Memphis.

Gaub became a member of the Rangers organization on May 24, after being waived by Tampa Bay.

The Rays had acquired him on April 5 from the Chicago Cubs.

Originally a 21st round pick (641st overall) by the Cleveland Indians in the 2006 June draft, Gaub was acquired by the Cubs, along with right-handed pitchers Chris Archer and Jeff Stevens, in exchange for infielder Mark DeRosa on Dec. 31, 2008.  He made his major league debut with the Cubs on Sept. 12 last season and went 0-0 with a 6.75 ERA (2 ER/2.2 IP) over 4 relief appearances in his only big league action to date.
