Righty Gaby Hernandez was designated for assignment to make room for Ryan Garko, according to a Mariners press release.
Hernandez, 24 in May, posted a 6.0 K/9, 3.0 BB/9, and 5.23 ERA in 146.3 Triple A innings last year. He was acquired from the Marlins for Arthur Rhodes at the '08 trade deadline. The Marlins had acquired Hernandez from the Mets for Paul Lo Duca in December of '05. Baseball America ranked Hernandez 21st among Mariners prospects heading into the '09 season, but he didn't crack their top 30 in the brand new 2010 Handbook.
