Taylor Ruck has been surprising people for months. On Thursday she surprised herself.

The 17-year-old phenom from Kelowna, B.C., won the 200-metre freestyle final in a Commonwealth Games and Canadian record time of one minute 54.81 seconds, erasing the mark of 1:55.57 set four years ago by defending champion Emma McKeon of Australia.

害羞草研究所淕oing into this race I think my expectations were just to try and get third which is what I was going in at (as the third-highest qualifier at 1:57.44),害羞草研究所� said Ruck, who won two relay bronze medals in the Rio Olympics. 害羞草研究所淪o anything better than that I was just going to be super-happy.害羞草研究所�

Ruck had to stave off a hard-charging Ariarne Titmus, a 17-year-old who won the 200, 400 and 800 freestyle at the Australian Commonwealth Games trials five weeks ago, in a heart-pounding final lap.

害羞草研究所淎n absolutely tremendous performance,害羞草研究所� said Swimming Canada high performance director John Atkinson.

Ruck then teamed up with Toronto害羞草研究所檚 Penny Oleksiak and Kayla Sanchez and Alexia Zevnik of Montreal to earn silver in a 4x100 relay won by Australia in a world-record time of 3:30.05.

Ruck brought the Canadians home with a blistering 51.82-second anchor leg for a time of 3:33.92. The Canadian record is 3:32.89, set by Oleksiak, Ruck and company in a bronze medal performance in Rio.

Canada also picked up another silver and a bronze in the pool, thanks to Sarah Mehain of Vernon, B.C., placing second and Tess Routliffe of Caledon, Ont., third in the women害羞草研究所檚 S7 (para) 50-metre butterfly.

害羞草研究所淚t害羞草研究所檚 been a great day,害羞草研究所� said Atkinson.

Ruck was second behind McKeon over the first 100 metres, but led after 150 metres and held off Titmus, who was fourth midway through the race, to touch the wall first.

害羞草研究所淕reat athletes know how to finish races and she finished it off well,害羞草研究所� said Atkinson.

Ruck wasn害羞草研究所檛 so sure.

害羞草研究所淚 saw Ariarne coming up and I thought she won. So it was like 害羞草研究所極h my gosh害羞草研究所� when I looked up at the board. I think I害羞草研究所檓 still in shock. I don害羞草研究所檛 think I害羞草研究所檝e processed it yet.害羞草研究所�

Getting her gold medal from Prince Charles wasn害羞草研究所檛 much of a help in terms of a reality check. 害羞草研究所淭hat was insane,害羞草研究所� she said, adding: 害羞草研究所淗e was really nice.害羞草研究所�

Titmus was four one-hundredths of a second behind Ruck in the 200 in a personal best time of 1:54.85 while McKeon, the bronze medallist in Rio, was third in 1:56.26.

Ruck also had to knife through a wall of sound at the Optus Aquatic Centre, with the crowd of 10,000 doing its best to power the Aussies on home.

Oleksiak, who won the 100 freestyle in Rio but did not compete in the 200 there, was seventh in 1:59.55.

害羞草研究所淚 think the relay was amazing and Taylor害羞草研究所檚 200 free was crazy,害羞草研究所� said the four-time Olympic medallist, whose grandmother died on the eve of the meet. 害羞草研究所淥verall I think it was a really really good night for Canada and I害羞草研究所檓 just excited for the rest of the meet.害羞草研究所�

Oleksiak finished second in her 100 butterfly semifinal to qualify for Friday害羞草研究所檚 final.

Ruck, who has verbally committed to attend Stanford University, has been serving notice recently that she is something very special.

She had set the Canadian record of 1:56.85 in the 200 freestyle in March in Atlanta with a sizzling swim in the final TYR Pro Swim Series stop in her final tune-up before the games. Ruck won three other events at the Atlanta meet including the 100 free where she beat world record-holder Sarah Sjostrom.

Ruck, who was born in Kelowna but moved to Scottsdale, Ariz., with her family when she was young, switched things up last year after failing in April to qualify for the world championships. She moved to Toronto in May to train with coach Ben Titley at the High Performance Centre-Ontario.

害羞草研究所淏en refocused her on going to the world junior championships,害羞草研究所� said Atkinson.

Ruck responded by winning seven medals 害羞草研究所� six gold and one silver 害羞草研究所� at the 2017 FINA World Junior Championships last August in Indianapolis.

At the Swim England National Winter Championships in December, she tied the 200 freestyle Canadian record and trimmed her 100 free and 200 backstroke times, setting a Canadian national age group record (15-17) in the 200.

Ruck came to the games with four times in the top eight in the world (in the 100 and 200 backstroke and 100 and 200 freestyle).

Atkinson calls it a 害羞草研究所漛reakout meet害羞草研究所� for Ruck, a six-footer with an equally big smile. Unlike Rio where she competed only in the relays, she has three more individual events here plus relays.

害羞草研究所淭he work that she害羞草研究所檚 been doing in a lot of these swim meets over the last year is preparing her to come here, be busy, work on recovery strategies between heats, finals, semifinals,害羞草研究所� said Atkinson. 害羞草研究所淎nd we want her to be swimming just as fast on Day 6 as she is on Day 1.害羞草研究所�

There were five other finals Thursday, with England winning four and Australia one.

Ottawa害羞草研究所檚 Erika Seltenreich-Hodgson finished 0.28 seconds out of a medal, finishing fourth in the women害羞草研究所檚 400 IM final won by England害羞草研究所檚 Aimee Willmott. Two-time defending champion Hannah Miley of Scotland was second and Australia害羞草研究所檚 Blair Evans third.

For Seltenreich-Hodgson, the disappointment of missing out on a medal was tempered by the fact she was coming back from a shoulder injury that has limited her preparations. The time of 4:38.51 was her best in four years.

Victoria害羞草研究所檚 Sarah Darcel led for more than half the race but was pegged back and finished fifth. Mary-Sophie Harvey Trois-Rivieres, Que., was eighth.

Victoria害羞草研究所檚 Jeremy Bagshaw was fifth in the men害羞草研究所檚 400 freestyle won by Australian Mack Horton.

The six-day swimming event wraps up Tuesday.

Four years ago in Glasgow, Canadian swimmers won 11 medals (4-1-6) to finish behind England害羞草研究所檚 28 (10-10-8) and Australia害羞草研究所檚 57 (19-21-17).

Ryan Cochrane and Audrey Lacroix, who won three of those gold medals in Glasgow, have since retired. Katerine Savard, who won the other gold four years ago, pulled out of these Games due to illness.
