The Mariners have designated Jose Yepez for assignment, tweets Shannon Drayer of MyNorthwest.com. The move clears a 40-man roster spot for Kyle Seager.
Yepez, 30, was hitting .276/.324/.347 in 105 plate appearances for Seattle Triple-A affiliate this year, his third at the level. He has never appeared in the big leagues. Seager, 23, hit .312/.381/.459 with their Double-A affiliate before making a quick stop with their Triple-A club. Baseball America ranked him as the Mariners' ninth best prospect before the season, noting that he "profiles best as a utility player."
