Oakland announced its 17 non-roster invitees to Spring Training, and the list includes hot-shot pitching prospects such as Trevor Cahill, Brett Anderson and Vin Mazzaro.
Also slated to suit up with the big leaguers -- early in camp, at least -- are first baseman Chris Carter, who led the Minor Leagues with 75 extra-base hits and 288 total bases for Class A Stockton, and second baseman Jemile Weeks, Oakland's top pick in the 2008 First-Year Player Draft.
Nine of the other invitees are from the A's Minor League system: pitchers Drew Bailey, Andrew Carignan, Brett Hunter, Jared Lansford, Tyson Ross and James Simmons; catcher Josh Donaldson; and infielders Adrian Cardenas and Sean Doolittle.
The A's also agreed to terms with righty Jerome Williams on a Minor League contract and will invite two players from Mexican League teams: pitcher Arnold Leon from Saltillo and catcher Joel Galarraga from Minatitlan.
Anderson and Cahill are the A's No. 1 and No. 2 prospects according to Baseball America. Anderson, who was acquired from Arizona in the Dan Haren trade, combined to go 11-5 with a 3.69 ERA in 20 games (19 starts) for Stockton and Double-A Midland.
