ARCADIA, Calif. – If he makes the Kentucky Derby, the even-tempered colt Journalism will not be intimidated by a crowd of more than 150,000. That is the opinion of jockey Umberto Rispoli, who worked Journalism an easy half-mile in 48.20 seconds last Sunday. The work was Journalism’s first since his highly rated win in the Grade 2 San Felipe Stakes on March 1 at Santa Anita.
