Barrington closed in style on Friday at the Mid-Suburban League girls track meet.
The Fillies capped things by taking first in the meet-ending 1,600-meter relay and to nail down their sixth MSL title with 140 points at Wheeling.
Palatine finished second with 137.5 points, just ahead of defending champion Prospect (136).
"I told the girls we had an opportunity, and they made the most of it," said Barrington coach Jody Gitelis. "The girls stepped up and did the job."
Sophomore Anne Cosio, freshman Kelsey Mclaurin, senior Stephanie Bergen and sophomore Sara-Kate Capel combined to lead the Fillies' 1,600 relay.
Capel was able to hold off Palatine sophomore Kelly O'Brien in the final lap.
"We knew what was on the line," said Capel. "But our coaches did a great job of putting us in position to win."
Barrington won the 400 relay (49.25) and 800 relay (1:45.62) and had a number of individuals fill the gaps -- including freshman Addi Coy, who took first in the 400 (58.86) and second in the 200. Coy also anchored the 400 relay.
"It feels amazing," said Coy of the conference title. "It still hasn't hit me yet. I knew we were capable, but to actually get it done is great."
Junior Nina Hodges gave the Fillies the victory in the 200, and also was part of the 400 and 800 relays.
Cossio gave the Fillies a lift with a third-place finish in the high jump (5-2) and a third-place finish in the 300 low hurdles (47.31). Capel added a second-place finish in the 300 lows (46.93).
Senior McCall Braun took third in the 100 high hurdles (15.83) and second in the long jump (18-1).
And freshman Kelsey McLaurin was part of the 400 relay, 800 relay, and 1,600 relay in aiding the Fillies' attack.
