Jack Marlatt made his last home meet for the Pekin co-op boys swimming and diving team a memorable one.

The senior won the 50 freestyle at the Mid-Illini Invitational on Saturday in :21.43, breaking Noah Barnard’s school record by the slimmest of margins: .01 seconds.

Barnard swam :21.44 in 2016 at the Normal West Sectional.

Adam Peterson, another Pekin senior, finished second to Marlatt in :21.53.

Normally they don’t swim the event at the same time.

“I put Jack and Adam together in the 50 to see what they could do,” said Pekin coach Christine Dunn. “Jack had a great start and stayed ahead of Adam the entire race. Both beat the state meet cut time, but they have to do that at sectionals, of course, to get to state.”

Marlatt also won the 100 backstroke (:55.61) and Peterson won the 100 freestyle (:47.62) at the Mid-Illini meet as Pekin finished third in the five-team field.

Dunlap co-op (394) and Washington co-op (344) were in front of Pekin (340). Metamora co-op (186) and Canton (19) followed.

It’s Dunlap’s eighth consecutive Mid-Illini championship, but the Eagles finished 154 points in front of runner-up Washington last year.

“We were only two points behind Washington going into the last event (400 freestyle relay) Saturday, but we couldn’t overtake them,” Dunn said. “I’m proud of what our guys accomplished. Washington has twice as many guys on their team as we do, and we finished only four points behind them.”

Washington’s Leo Edwards, Dawson Dobbelaire, Christian Buck and Camden Schmidt combined to finish third in the 400 freestyle relay (3:36.44).

Pekin’s Isaac Watson, Matthew Peterson, Sam Dunn and Garrett Oliver were fourth (3:52.59).

The Dragons won the other two relays.

Marlatt, Adam Peterson, Alex Kula and Tyler Cummins won the 200 medley relay (1:41.59) and Marlatt, Cummins, Kula and Adam Peterson won the 200 freestyle relay in a season-best time (1:29.92).

Marlatt was a perfect 4-for-4 in the meet. He swam the maximum four events, and won them all.

Kula also was second in the 100 butterfly (:55.98) and third in the 200 freestyle (1:50.73). Both were personal-best times.

“Alex had stiff competition in the 200 freestyle,” Dunn said.

Other good Pekin swims noted by Dunn were Watson (2:29.45) and Sam Dunn (2:30.08) in the 200 IM and Dakota Schultz (6:07.83) in the 500 freestyle.

Pekin diver Jayson Presley did well, Dunn said, scoring 241.35 points and finishing seventh.

Dunlap’s and Washington’s depth in diving helped them. Each team had three divers, and they finished in front of Presley.

Zach Boley was Dunlap’s star.

He won the 100 butterfly (:53.47) and 500 freestyle (4:49.94) and was on the winning 400 freestyle relay team (3:26.20) along with Henry Yi, Zach Glover and Ben Owens.

The other individual wins for the Eagles came from Bryce Young in the 200 IM (2:08.95) and Taron Mackey in diving (329.80 points).

Metamora sophomore Justin Alderson was a two-time champ for the second straight year, winning the 100 breaststroke (:59.75) with an area-best time and the 200 freestyle (1:46.21).

FOUR FOR IRISH: Peoria Notre Dame made it 4-for-4 in the Big 12 Conference meet Saturday.

The Irish won their fourth straight Big 12 title since joining the conference in 2015, claiming nine of the 12 titles for a team total of 261 points at Central Park Pool in Peoria.

Normal Community edged Peoria Richwoods for second place by two points, 226.5 to 224.5.

“Normal Community was the team to beat coming in,” ND coach Shawn Ribordy said. “The big thing we did today was, I ran the point totals after seeing the heat sheet and decided it was so close, we really tried to spread our talent out.

“I spread out our talent among the three relays, and pulled in some of my younger guys to swim a leg in each of those relays.”

Two-time state champion Colton Paulson won the 200 freestyle (1:40.09) and 100 freestyle (:47.08), and anchored the winning 200 freestyle (1:30.13) and 400 freestyle relays (3:22.33) for the Irish.
