Kansas City, KS (Sports Network) - Sporting Kansas City announced Thursday that it has signed midfielder Christian Duke and defender Mechack Jerome.

"We are very happy to add Jerome and Duke to the team," Sporting manager Peter Vermes said. "They both have a lot of potential and earned their roster spots in preseason. Duke is an academy player and Mechack is from Orlando City so it's great to see our academy system and our partnership with Orlando City both working so well."

Duke, 21, was selected in the first round of the 2013 MLS Supplemental Draft last month out of the University of San Diego. He is considered an off-budget player so his salary will not count against Sporting's cap.

Jerome, 22, played each of the last two seasons with Orlando City SC, Sporting Kansas City's USL Pro affiliate. He logged 20 appearances for the club in 2012, scoring one goal and adding three assists.
