The A's invited C Landon Powell, UTL Gregorio Petit, RF Javier Herrera, OF Matt Carson, 2B Corey Wimberly, 2B Jemile Weeks, 1B Sean Doolittle, 1B Chris C. Carter, 3B Joe Dillon, SS Adrian Cardenas, C Josh Donaldson, RP James J. Simmons, RP Tyson Ross, SP Vin Mazzaro, SP Jared Lansford, RP Brett Hunter, SP Andrew Carignan, SP Trevor Cahill, SP Brett Anderson and RP Drew Bailey.
Many of these guys are top A's prospects who just haven't yet had to be added to the 40-man roster. Cahill and Anderson are two of the best pitching prospects in baseball and are a pretty good bet to significantly impact all Fantasy leagues once they arrive -- perhaps out of spring training as a No. 5 starter, or more likely midseason. Carter, Weeks and Cardenas are elite prospects in their own right. All of these players figure to open the year in the minors, but they are certainly ones to watch. Track their progress in deeper AL-only and long-term keeper leagues.
