From the Backstretch by Reuben Frank

Pennsauken sophomore Sianni Wynn smashed the South Jersey record in the 300-meter dash Sunday at the 116th annual Millrose Games in New York.

Wynn ran 38.66 over a lap and a half at the Armory, breaking the South Jersey mark of 39.16 set 18 years ago by Winslow Township’s Krystal Cantey at the Archbishop Malloy Stanner Games at the Armory Jan. 14, 2006.

Wynn’s time is No. 4 in state history, just behind Union Catholic’s Rhia Randolph, who ran 38.59 in the same race (but a different section).

The South Jersey record was Wynn’s second in seven days on the Armory track, and in both cases she broke a record held by Cantey. Wynn ran 24.12 for 200 meters on Monday, breaking Cantey’s South Jersey mark of 24.38 set in the prelims of 2006 Easterns at the Armory.

Wynn ran 39.17 at the Armory last year, which at the time was 6th-fastest in state history.

Wynn is the top seed in the 400 for Saturday’s state Group 3 meet with her 56.93 at sectionals. She’s the No. 3 seed in the 55 at 7.07, behind Timber Creek junior Ryan Jennings and Timber Creek senior Naylah Jones. All three have PRs of exactly 7.00.
