Canada’s Gabe Mastromatteo lowered his own Canadian age group record below 1:01 in the 100 breast during semifinals of the 100 breast at World Juniors this evening.

Mastromatteo, who turned 17 in April, went 1:00.76 to qualify third overall out of semifinals. That bettered his old age record (for 15-17 year olds) of 1:01.24 from April. Mastromatteo hit that time at Canadian Trials on April 4 in Toronto.

The rising Canadian was faster on both of his 50 splits tonight compared to his April swim, though most of his improvement came over the front half. His 28.5 split in semifinals was three tenths faster than his opening leg at Canadian Trials. On the other hand, his 32.2 closing speed was the 4th-best final split of anyone in tonight’s semifinal field.

Splits comparison:

Canadian Trials (April)
World Juniors (August)
1st 50: 28.85 28.56
2nd 50: 32.39 32.20
Final time: 1:01.24 1:00.76

Per our research, that swim moves Mastromatteo to #5 all-time among Canadian men of any age. The Canadian record remains at 59.85 from the 2012 Olympics. Scott Dickens holds that record. We could only find two Canadian men in history to break a minute: Dickens, and Richard Funkwho went 59.89 back in 2017. Here are the top Canadian men in history, per world rankings:

Top Canadian Men All-Time, 100m Breaststroke

  1. Scott Dickens (2012) – 59.85
  2. Richard Funk (2017) – 59.89
  3. Mathieu Bois (2009) – 1:00.23
  4. Jason Block (2016) – 1:00.59
  5. Gabe Mastromatteo (2019) – 1:00.76

Mastromatteo will have a shot to move up that list in tomorrow’s final.

Tremendous improvement. Would like to see both Funk and Gabe both get under Fina A next April. We would be able to argue who should swim on medley relay in Tokyo. This hasn’t happened with Canadian men in a while.


I think you are missing Paul Kornfeld’s swim from 2009 at the Canadian World Champ trials for #5 at 1:00.65 actually (
