The opportunity for a budding young racecaller to join Tapp was the stepping stone to Wrona's now long time of living and working in the United States.
He was hired as the voice of Santa Anita Park in March 2016,[2] replacing Trevor Denman, and remained there until he was succeeded by Frank Mirahmadi following the 2018 Autumn meet.
[7] On December 10, 1999, at Hollywood Park, Wrona called the race that saw Laffit Pincay Jr pass Bill Shoemaker for most career victories by a jockey.
Nearly seven years later, on December 1, 2006, Wrona was the announcer for the race at Bay Meadows in which Russell Baze passed Pincay for the same honors.
[7] On November 11, 2008, as one of five announcers invited to audition for the job at Churchill Downs, Wrona called all seven of Julien Leparoux's winners.
In 2012, Wrona called South America's biggest race, the Gran Premio Carlos Pellegrini, from the Hipodromo de San Isidro in Buenos Aires, Argentina for the HRTV network.
