Conant excelled in Saturday's boys swimming sectional meet hosted by Glenbrook North, finishing second in the team standings with 177 points, close behind the Spartans (185) and just ahead of Maine South (167).
The Cougars qualified both freestyle relays to the state meet and can look forward to two individuals swims each for senior Jonathan Burke and juniors Martin Pozniak and Alex Shozda.
Burke won the 200-yard freestyle (1:41.41) and 500 free (4:35.01), and Shozda won the 100 free (46.97) and placed second in the 100 back (53.02).
Pozniak was second in the 200 IM (1:57.55) and won the 100 fly (51.84).
Joining the Conant trio on the 200 free relay was senior Zon Wang; on the 400 relay senior Adrian Lisowski had a leg.
Maine West senior Brian Wasicak had terrific performances, winning the 200 IM in 1:55.63 and the 100 breast in 58.70 to earn a third straight trip to state.
Wheeling had a pair of individual qualifiers, as freshman Jake Noel won the 100 back in 52.76 and junior Bryce Maczko placed second in the 100 free in 47.61.
Prospect junior Nathanael Ginnodo placed second in the 100 breast in a state-qualifying 1:00.04.
Hersey's medley relay of Jamey Hill, Michael Buffa, Samuel Kim and Connor Reynolds earned a spot in the state meet by winning in 1:40.28.
In diving, Hersey's Mat Obstoj had the fourth-best score, 407.10, which will almost certainly earn him an at-large berth to state. Conant's Bartek Turek was seventh at 373.80, and Hersey's Jack Kintzle was eighth at 368.80.
