The Athletics have designated catcher George Kottaras for assignment, according to a team press release. The move was made to free up 40-man roster space for the newly-acquired John Jaso, who will take Kottaras' spot as Oakland's primary left-handed hitting catching option.
Kottaras was acquired in July from the Brewers and hit .212/.280/.471 in 93 PAs as an Athletic, giving him a total slash line of .211/.351/.415 in 209 plate appearances for the 2012 season. Kottaras recently avoided arbitration by agreeing with the A's on a $1MM contract for 2013.
