Carter, 24, was 1-4 with 22 saves and had a 3.92 ERA and with 58 strikeouts in 57 1/3 innings with Birmingham. He tied for the Southern League lead in saves and was named to the Southern League midseason All-Star Game in his first season as a reliever. The 6-foot-3 pitcher, who pitched for USA Baseball at the 2010 Pan Am Games, could possibly fight for one of the last bullpen spots for the White Sox in 2011.
The 21-year-old Escobar combined to hit .277 with 11 triples, six home runs, 61 RBIs and 79 runs scored in 136 games between Class A Winston-Salem and Birmingham.
Escobar was named to the Carolina League mid and postseason All-Star teams and was named by Baseball American as the best defensive shortstop in the Carolina League.
Carter and Escobar were two of the White Sox prospects who took part in the Arizona Fall League, and both were selected to play in the AFL's Rising Stars Game. Carter posted a 3.60 ERA with three saves and 16 strikeouts in 10 relief appearances for the Peoria Saguaros. Escobar, a switch-hitter, batted .300 with four home runs and 15 RBIs in 28 games.
Jones, 24, was 11-6 with a 4.08 ERA and had 109 strikeouts in 28 starts for Winston-Salem in his first season working exclusively as a starter. Jones has gone 17-18 with a 4.48 ERA and 303 strikeouts in four Minor League seasons.
All three players are now protected from next month's Rule 5 Draft. If a non-protected player is selected in the Major League portion of the Draft on Dec. 9 in Orlando, Fla., he must stick with the Major League club that claims him -- either on the active roster or disabled list -- for the length of the 2011 season or else be offered back to the White Sox for $25,000, half the fee for selecting such a player.
Eligible players to be selected in the Rule 5 Draft are those who were signed at 19 or older and who have been in an organization for at least four years, or those signed at 18 or younger who have been in a system for at least five years and are not on the 40-man roster.
