CHARLESTON — Pressure produces diamonds. And no one embraced the pressure at the Illinois High School Association Class 3A state track and field championships here Saturday better than Evanston junior Jaden Jean-Paul. With the state team title on the line, Jean-Paul rose to the occasion and captured the state high jump crown to deliver Evanston’s first boys track championship since 1979 in a dramatic finish to the two-day meet for the Wildkits on the blue oval track at Eastern Illinois University.
