The Mariners have designated minor leaguer Vinnie Catricala for assignment, according to Shannon Drayer of 710 ESPN (via Twitter). The move will allow Seattle to promote Jeremy Bonderman for today's game.
Catricala, 24, has a .253/.318/.351 slash line this season for the Mariners' Double-A affiliate. The Mariners made another minor move earlier today when they sent outfielder/third baseman Francisco Martinez back to the Tigers.
