Keep your eyes on the top seeds in this morning’s events. We could see some fantastic swims out of this group, particularly in the finals session tonight. Bulgaria’s Petar Mitsin, who burst onto the scene this year, comes in as the top seed in the boys 400 free. The Bulgarian Record holder in the event, Mitsin popped a 3:44.31 at the European Junior Championships back in July. He enters the meet this morning as the top seed by nearly 3 full seconds.
Similarly, American Leah Hayes comes in as the top seed in the girls 400 IM. Hayes is entered at 4:38.45, making her the only swimmer in the field entered under 4:40.
Another American, Daniel Diehl, comes in as the top seed by a huge margin in the boys 100 back. Diehl is entered at 53.07, marking the fastest seed time in the event by more than a second.
Estonia’s Eneli Jefimova comes in as the top seed in the girls 50 breast this morning. Jefimova was notably a finalist in the women’s 50 breast at the World Championships in Fukuoka a little over a month ago. She enters as the top seed by roughly half-a-second.

TOP 8 QUALIFIERS:

Prelims of the boys 400 free marked the first event of the 2023 World Junior Championships, and it turned into a tight one. 1st through 8th were separated by just 1.81 seconds this morning, setting up what ought be a great race in tonight’s final.
That being said, Bulgaria’s Petar Mitsin was the top performer of the morning, clocking a 3:50.52. While the field looks tight right now, Mitsin holds the top time in terms of personal bests in this field by a wide margin. His World Junior Record of 3:44.31, which he set earlier this summer, stood as one of the top times in the world this year for a while. Mitsin was controlled this morning, only splitting 1:53.64 on the opening 200m of the race. We can reasonably expect he’ll be somewhere around 2 seconds faster on the front half of the race in finals tonight.
Italian Alessandro Ragaini was just off Mitsin’s time this morning, touching with the second overall swim in 3:50.65. Just having turned 17 years old a month ago, Ragaini could’ve beaten Mitsin’s time this morning, if not for a 29.90 on the 6th 50 of the race, which sticks out as his slowest 50 split of the morning by a considerable margin.
Canadian Lorne Wigginton also posted a 3:50-point this morning, coming in 3rd overall at 3:50.72. Winnington was out the slowest of the top 3 this morning, however, he put up a speedy last 100m, splitting 57.51, which was quite a bit faster than both Mitsin and Ragaini. If that tells us anything it’s that we should keep an eye on him towards the end of the race tonight in the final.

It didn’t take long for us to see the first Championship Record performance of the meet. Estonia’s Eneli Jefimova was dominant in the girls 50 breast this morning, throwing down a 30.19 to lead the field by well over half a second. Not only did Jefimova blow away the field this morning, she shattered the Championship Record of 30.60, which Benedetta Pilato set in 2019.
Jefimova is capping off a successful summer. At the World Championships in Fukuoka a little over a month ago, the youngster qualified for the final of the women’s 50 breast. She holds the Estonian Record at 30.08 from the 2022 World Champs last summer.
Impressively, the top 6 swimmers this morning were all under the time it took to win gold in the event last year (31.55). Canadian Alexanne Lepage was the only other swimmer in the field to dip under 31 seconds, swimming a 30.82 for the 2nd overall time. Though Lepage was the only other 30-point in the field, New Zealand’s Monique Wieruszowski was right behind, swimming a 31.06.

He was out quick this morning, posting a 26.13 on the opening 50m, which put him in the lead by a significant margin going into and out of the turn.
Ukrainian Oleksandr Zheltiakov wasn’t too far off Knedla’s time this morning, clocking the 2nd overall time with a 54.46. He swam the race quite differently from Knedla, however, as Zheltiakov was out slower than Knedla, but posted the top split in the field this morning on the 2nd 50 (27.68).
Italian Christian Bacico was also under 55 seconds this morning, swimming a 54.57 for 3rd overall.
American Daniel Diehl, the top seed coming into the morning, came in 6th with a 55.21. Don’t let that swim fool you, Diehl has the fastest personal best in this field by a very wide margin. We’ll be looking for him to be considerably faster tonight in semifinals.
Also of note, host country Israel had its first swimmer of the meet advance past prelims, as Aukan Goldin came in 16th this morning with a 56.23.

The United States and Canada shone in prelims of the girls 400 IM this morning. Coming into the meet as the top seed in the event, American Leah Hayes clocked the top time of the morning, speeding to a 4:41.49. It was a very solid prelims swim for Hayes, who has a personal best of 4:38.45, which she swam at the U.S. World Champs Trials back at the end of June. Hayes, who in many ways is a pure IM’er, swam a well-rounded race this morning. She was out in 1:02.05 on fly, then split 1:11.44 on back, 1:21.20 on breast, and 1:06.90 on free.
Hayes heads into tonight’s final as the top seed by a comfortable margin. Canadian Ella Jansen was 2nd this morning in 4;44.26. Jansen was within a second of Hayes’ time on the first 200m this morning, however, she really fell behind on breaststroke, where she split 1:23.00 to Hayes’ 1:21.20. Breaststroke will be critical tonight in the final. There is a case to be made it’s Hayes’ best stroke, so it will be incumbent on the other swimmers to mitigate her ability to pull ahead on that 100.
Coming in 3rd this morning was American Lilla Bognar, who swam a 4:44.90. Bognar, a great backstroker, had the fastest back split in the field this morning, clocking a 1:11.21.
Canadian Julie Brousseau was 4th this morning in 4:45.66. She was particularly strong on breaststroke, where she split 1:22.60.
