The Athletics designated infielder Adam Rosales for assignment today to open a roster spot for Grant Green, announced the team on Twitter. Susan Slusser of the San Francisco Chronicle first reported this scenario last night.
Rosales, 30, is hitting .200/.273/.331 in 147 plate appearances this year. He's mostly played shortstop, but also appeared at second base, third base, and left field. Rosales was drafted by the Reds in the 12th round in 2005, a round which also produced big leaguers Matt Joyce and Craig Stammen. The A's acquired Rosales and Willy Taveras from the A's for Aaron Miles and a player to be named later in February 2010; Rosales was the good part of a bad contract swap. He's earning $700K after being eligible for arbitration for the second time during the offseason.
Green, 25, was drafted 13th overall out of USC by the A's in 2009. Only one college player drafted that early has yet to appear in the Majors: catcher Tony Sanchez, drafted fourth by the Pirates. Green, a second baseman this year at Triple-A, was hitting .318/.374/.500 with 11 home runs in 388 plate appearances.
