The Royals claimed Joaquin Arias off of waivers from the Mets. New York acquired Arias from the Rangers in the Jeff Francoeur trade after the Rangers designated the infielder for assignment in August.
The Rangers acquired Arias in the 2004 Alfonso Soriano–Alex Rodriguez trade. He did have a solid 2008 campaign as a reserve for the Rangers, but this year he hit just .258/.280/.320 between the Rangers and Mets. The 26-year-old is not yet arbitration eligible.
