Corporan (thumb) refused his outright assignment Tuesday and instead opted for free agency, the Rangers' official site reports.

EDGE Analysis

Corporan was outrighted last Wednesday, but rather than stick with the Rangers, he'll test the open market. In 33 games with the big club this season, the catcher fell below the Mendoza Line, recording a .178/.244/.299 line with three homers in 107 at-bats.
