Downers Grove South stormed to the Peoria Central Invitational title with 69 points at Detweiller Park in Peoria on Saturday.
The Mustangs placed five runners in the top 21 in dominating the 43-team field.
Mundelein (162 points) took second followed by Prospect (172 points), Hoffman Estates (222 points), and Cary-Grove (240 points).
McHenry sophomore Lauren Opatrny won the individual title in 17:23, followed by Fenwick sophomore Olivia Ryan (17:28), Galesburg senior Stephanie Saey (17:30), and Prospect senior Lauren Poplawski (17:34).
Senior Katherine Strelau (17:47) and sophomore Amanda Thate (17:53) took 7th and 10th place to lead Downers Grove South.
Junior Haley Albers (18:06), junior Meaghan Bosman (18:15), and sophomore Abby Kargol (18:19) then secured 14th, 17th, and 21st place to pace the Mustangs attack.
Senior Ellie Palacios (17:59) finished 12th in pacing Mundelein to an impressive second place finish.
Poplawski set the tone for Prospect, helping the Knights get out to a fast start. Junior Katrina Leeney (18:35) also supported the Knights with a 28th place finish.
Prospect was without No. 1 runner senior Brooke Wolfe, and the Knights were unable to sustain their fast start, fading in the final two miles.
"We got out fast in the first mile," said Prospect coach Dave Wurster of his team's early performance. "Maybe a little too fast, and it may have cost us."
Sophomore Alondra Aguirre (18:14) and junior Solome Haile (18:17) paced Hoffman by taking 16th and 20th place.
"We're looking for more consistency," said Hoffman coach Kirk Macnider of his team that was coming off a tough triangular meet at Palatine on Thursday. "We have the ability to be very successful; we just have to put it together."
Sophomore Talia Duzey (17:58) continued her impressive season notching an 11th place finish leading Cary-Grove to fifth place.
Freshman Gabby Sanchez (19:36) took 84th place pacing Rolling Meadows to 24th place
