WINDSOR, Ont. – Canada went from high to low at the FINA World Swimming Championships (25m) Tuesday.

After Taylor Ruck captured a bronze medal in the women’s 200-m freestyle earlier in the night, Canada appeared to have added a silver in the women’s 4×100-m free relay. The team was disqualified, however, due to an administrative error that led to them swimming in an order different from that submitted. Sandrine Mainville, Alexia Zevnik, Michelle Williams and Penny Oleksiak were left confused and disappointed as their disqualification was announced.

“Obviously things like that are a huge disappointment, but you have to kind of look at it as something that was completely out of our control. The only thing we can do is move forward from that. It was Day 1, there’s five more days of racing to go and this will motivate us even more to just get back on the podium again,” said Williams, part of the bronze medal team from the Rio 2016 Olympic Games.

“We’re still second in the world and we know it.”

“We’re still second in the world and we know it.”

“We had a relay card mix-up tonight,” explained Swimming Canada High Performance Director John Atkinson. “We have an internal team process with certain checks and balances in place. Obviously that didn’t work tonight.

“This is by no means any fault of the athletes. The athletes swam in the order that they were instructed to swim in. That wasn’t the order that went in on the relay card.”

“We’ve already reviewed what happened and what broke down,” Atkinson said. “We have to take that on the chin. We’re sorry for the athletes that swam in the heat this morning and the final tonight.”

The relay would have given Ruck her second medal of the night, as she swam the morning heat to qualify Canada for the final. The 16-year-old Kelowna, B.C., native still left the WFCU Centre in Windsor, Ont., with individual bronze in the 200-m freestyle.

Ruck said her goal was to go under two minutes in the 200 free in the morning heats. By the end of the night she’d set a world junior and Canadian record of 1:52.50, good for a bronze medal.

“It feels amazing. I wasn’t even expecting to place in finals. I’ve been training hard,” said Ruck, who won two relay bronzes at the Rio 2016 Olympic Games, but had yet to swim an individual event for the senior national team.

“It definitely makes me happy just to be able to swim some individual events. In Rio I did some relays and we got bronze there too, it just makes me happy to have a small little win,” she said.

Katerine Savard of Pont-Rouge, Que., also went under the previous Canadian record, finishing sixth in 1:54.21.

Meanwhile, hometown girl Kylie Masse advanced to the final of the 100-m backstroke, the same event that saw her earn bronze in Rio. Masse posted the fastest semifinal time at 56.19 to earn Lane 4 for Wednesday evening’s final.

“I was a bit more nervous for this morning than I was tonight. It was nice to have the first race over with this morning, get my feet wet and get the jitters out. I just tried to focus on a few things from my prelims race to this race and I’m hoping to do the same going into tomorrow night,” said Masse, 20.

In other action, Rachel Nicol of Lethbridge, Alta., came 10^th in the women’s 50-m breaststroke with a personal best of 30.38. Javier Acevedo of Scarborough, Ont., shaved his moustache – and 0.16 off his personal best – but it wasn’t quite enough to advance to the 100-m backstroke final. Acevedo’s time of 51.16 earned him a 13^th-place finish.

The world short-course championships run through Sunday. The WFCU Centre, home to junior hockey’s Windsor Spitfires, has been converted to house a temporary pool where 933 athletes from 164 countries will compete for 46 gold medals. More than 35,000 spectators are expected to visit the WFCU Centre over the course of the six-day competition.

“It’s incredible. It definitely looks different from the last time I was here, which was for a hockey game. It’s super cool that this is even possible and I’m excited for the rest of the week,” Masse said.

Preliminary heats are at 9:30 a.m. each morning, with finals set for 6:30 p.m. each night. CBCSports.ca is streaming the championships beginning Tuesday at 9:30 a.m. ET at http://www.cbc.ca/sports/olympics/summer/aquatics/world-short-course-world-championships-1.3881730
