But it's two pitches he threw at a Chicago White Sox game that has gathered major-league attention for the Illinois State University commit.
Duncheon was at the May 9 White Sox game against the Mariners in Rate Field when he spotted a radar gun in a pitching booth set up for fans in the concourse.
Of course, he had to try it.
He fired a pitch that registered at 97 mph and was declared by the White Sox as a record for fastest pitch thrown by a fan there.
Duncheon wasn't done. Without his coaches knowing, he showed up at the pitching booth again and beat his own record, throwing a pitch 98 mph.
Actually, RJ was keeping this video from his coaches as he wasn’t supposed to go back and beat his record. Oh well, he threw a complete game Monday anyway. pic.twitter.com/3LVSm738Nk
