White Sox pitching prospect Michael Kopech threw his first official bullpen session of spring training Wednesday with pitching coach Don Cooper standing right next to him, chirping comments and instructions as he threw.
Sox executives and coaches also were scattered around to watch the line of pitchers throw, though undoubtedly many eyes were on the right-hander who MLB.com ranked the No. 16 prospect in baseball.
Kopech, 20, joined the Sox in December from the Red Sox in the Chris Sale trade, and his triple-digit fastball already has fans buzzing.
