Casey Kelly, the two-way player widely regarded as the best prospect in the Red Sox' farm system, will play in the Arizona Fall League as a shortstop.
Kelly, a first-round draft pick in 2008, went 7-5 with a 2.08 ERA in Class A Greenville and Advanced A Salem in the season's first half, earning an invitation to play in the Futures Game. In the second half of the season, Kelly batted .222 in 40 games as a shortstop between the Gulf Coast League and Greenville.
Sox officials will convene with Kelly some time in December to discuss the next step in his unique career. Earlier this season, Sox director of player development Mike Hazen said the Sox are not yet comitted to choosing one position or the other.
Kelly completes the Sox' Arizona Fall League participants, all of whom will play for the Mesa Solar Sox. Their three pitchers and Randor Bierd, Dustin Richardson, and Chris Province. Their four position players are catcher Luis Exposito, outfielder Ryan Kalish, shortstop Jose Iglesias, and Kelly.
