RIO — An Olympian from South Jersey was part of history at the Rio as three Americans swept the 100-meter hurdles on Wednesday.

Pleasantville's Nia Ali, 27, took silver in the women's 100-meter hurdles finals — with teammates Brianna Rollins and Kristi Castlin taking the gold and bronze. The trio was the first group from the same country to sweep the medals in the event.

"Whoa!" tweeted the 2006 graduate of Pleasantville High School after her accomplishment, witnessed by her 15-month-old son Titus, who sat with Ali's mother, Melita Johnson. Afterward, TItus and Ali took a victory lap.

Ali is originally from Philadelphia and moved to Pleasantville for her senior year according to the Press of Atlantic City.

According to the US Olympic Committee, Ali is one of 10 mothers on the U.S. Olympic team. Running is a family affair: Titus' father, Michael Tinsley will run Thursday in the 400-meter hurdles.

The sweep was part of a winning night for Team USA, which inspired Ali.  In a span of about 60 minutes Wednesday night, U.S. athletes hauled in a bevy of medals: Tianna Bartoletta and Brittney Reese went 1-2 in the long jump and Tori Bowie captured a bronze in the 200.

Ali watched Bowie, her suitemate in Rio and the rest of the team as they won four gold, six silver and six bronze medals.

"They smiled at me and were like, 'It's time. Do your part.' 'I need to go out there and do my part.' For Team USA, I knew it would be a great thing," Ali said.
