The Mariners announced that they have designated outfielder Johermyn Chavez for assignment. The move creates a 40-man roster spot for the team, which added Mike Carp, Luis Jimenez, Shawn Kelley, Alex Liddi, Hector Noesi, Carlos Triunfel and Casper Wells to the active MLB roster today.
Chavez spent most of the 2012 season with Seattle's Double-A Jackson affiliate. The 23-year-old posted a .232/.339/.386 batting line in 288 plate appearances at that level this year. The Mariners now have 10 days to trade, release or outright Chavez, who was dealt to Seattle with Brandon League for Brandon Morrow.
