Having to settle for three second-place finishes on Saturday, Alia Atkinson came out Sunday with a vengeance winning the 100m breaststroke in a time just shy of her world record.

The 31-year-old Olympian won the swim in 1:02.66, just out her world record of 1:02.36 in the semi-finals of the International Swimming League. It was the only time under 1:03 this year and is her fourth fastest time ever in the event.

As the London Roar make the push for the final, Atkinson stepped to meet the occasion winning by a clear 0.89s over Bennedetta Pilato (1:03.55) of reigning champions Energy Standard and Emily Escobedo of New York Breakers (1:04.31).

She was also a member of the Roar’s 4x100m medley relay team that clocked 3:46.59 to finish second to Energy Standard’s 3:45.58.

The win earned Atkinson and her team a valuable 15 points, which she added to the 12.5 points she won on Saturday.

It was another day of standout performances from the 31-year-old Jamaican who was second to Pilato (28.86) in the 50m breaststroke, touching in a quick 29.30.

Also on Saturday, Atkinson was seventh in 100m butterfly in a new national record of 57.13, breaking the record of 57.21 set on November 9.

When Alia Atkinson won the 50m breaststroke for the London Roar on Friday, it extended her win-streak to 12 dating back four years. The last time she lost a race in the 50m breaststroke was at the 2016 Short Course Championships where she won silver.

She followed up on Saturday, winning the 100m breaststroke in 1:03.75 ahead of teammate Annie Lazor (1:04.45) in a 1-2 finish that gave the Roar a 35-point lead. In between, she was a member of the London Roar’s winning 4x100m medley relay team and she also won her Skins races in 29.61 and 29.89, respectively that earned her and her team triple points.

The performances have meant that she was third in the MVP list for the meet.

But even as she continues to rack up victories for her new ISL team, the 2018 World Championship double-gold medalist believes her best performances are still to come.

“The plan is to build and get better each meet,” the 50m world-record holder said while speaking with Sportsmax.TV.

“This meet I did what I needed to secure the win for my team, but on a personal note, I would have liked to feel more ‘sprinty’ and strong in the races.  I need a bit more time to feel like my faster self. I am still 1.5 seconds away in the 100 and a second a way in the 50.”

Regarding her 50m win streak, she said there was no mystery as to why she has not lost a race in four years.

“It’s not a secret. I actually don't think about the streak and treat every race like it's the first,” she said.

At the end of action on Saturday, the London Roar hold a slim lead over the LA Current. The Roar have amassed 499 points with the Current on 478.5 points. Tokyo Frog Kings are on 446.5 points.
