Pennsauken junior Sianni Wynn raced to a South Jersey record and the 5th-fastest time in state hitory in the 400-meter dash Saturday on her home track at Pennsauken.
Competing in the Burlington County Scholastic League Liberty Division race, Wynn ran 52.80, breaking the South Jersey record of 52.91 set by Seneca’s Michelle Brown at 2009 Greensboro Nationals.
The only faster times in state history were run by Olympic gold medalists Sydney McLaughlin and Athing Mu as well as Olivia Baker and Mikele Barber.
Wynn’s previous 400 PR was a 53.45 when she won the state Group 4 race in Somerset last June. Wynn has already set state indoor records in the 60-meter dash [7.29] and 200-meter dash [23.31. She’s run 11.36 and 23.57 wind-legal outdoors.
Wynn broke the Camden County record of 53.16 set by Eastern’s Natalie Dumas when she won the Meet of Champions at Pennsauken last June. That performance broke Wynn’s county record of 53.45 from states a week earlier.
Wynn also broke the Liberty Division and overall meet records of 55.26 set in 2022 by Willingboro’s Okechi Ogbuokiri.
