The A's have designated third baseman Vinnie Catricala for assignment, according to Susan Slusser of the San Francisco Chronicle (Twitter link). The move will clear a 40-man roster space for Adam Rosales, who is rejoining the team after being designated for assignment and outrighted earlier this month.
The A's acquired Catricala, 24, from the Mariners in exchange for cash considerations after Seattle designated him for assignment earlier this season. After hitting .253/.318/.351 through 48 games for the Mariners' Double-A affiliate, Catricala's production worsened at Double-A Midland for the A's. He hit just .219/.292/.297 in 33 games.
Catricala ranked as the Mariners' No. 9 prospect prior to the 2012 season, according to Baseball America. However, he dropped to 26th on that list this season and has likely seen his stock fall further with a rough year at the plate.
