Hernandez (abdomen) will start Saturday's game against the Pirates, Lynn Worthy of The Kansas City Star reports.
Hernandez has made two appearances in long relief this season and suffered a stomach contusion in his last outing. However, he'll be healthy enough to make his first major-league start Saturday as Matt Harvey will be demoted to a bullpen role. Hernandez has been effective over his limited major-league sample, recording a 1.42 ERA and 1.11 WHIP over 6.1 innings during his two appearances. It's unclear whether the right-hander will remain in the rotation to end the season or whether he'll return to a bullpen role following Saturday's start.
