He went on to win silver in the 800 free and bronze in the 1500 free at that meet. However, Short has largely struggled since; he fell to fourth place in the event at the Olympics, missing the podium by 14-hundredths.<\/p>\n<p>Meanwhile, Germany&#8217;s\u00a0<strong>Lukas Martens<\/strong> has since emerged as the world&#8217;s dominant 400 freestyler. Martens won Olympic gold last year in Paris, and earlier this year, he finally knocked the legendary world record of\u00a0<strong>Paul Biedermann<\/strong> from the books. Martens clocked 3:39.96, clipping the 3:40.07 that had stood since the supersuit era. But Short has responded in fine form since then, going 3:41.09 at Australian Trials in June, and the two will face off for the world title Sunday evening.<\/p>\n<p>Short dominated heat four in prelims, coming within a second of world-record pace for much of the race before pulling off the pace down the stretch. He finished in 3:42.07, a second off his time from June but a half-second quicker than he went in the Olympic final. Martens followed that up by winning his heat comfortably in 3:43.81.<\/p>\n<p>There was a gap behind the two top seeds, but the rest of the field was fairly tightly packed. Korea&#8217;s\u00a0<strong>Kim Woo-min<\/strong> qualified third in 3:44.99 as he seeks to repeat the gold medal he won at last February&#8217;s Worlds in Doha. Fourth went to Bulgaria&#8217;s\u00a0<strong>Petar Mitsin<\/strong>, who went 3:45.01 before the seeded heats. It took a time under 3:46 to reach the final as China&#8217;s <strong>Zhang<\/strong><strong>\u00a0Zhanshuo<\/strong> (3:45.26), Sweden&#8217;s\u00a0<strong>Victor Johansson<\/strong> (3:45.72), Germany&#8217;s <strong>Oliver Klemet<\/strong> (3:45.72) and, Italy&#8217;s <strong>Marco de Tullio<\/strong> (3:45.88) reached the final.<\/p>\n<p>The swimmers that missed the final included Australia&#8217;s\u00a0<strong>Elijah Winnington<\/strong>, the 2022 world champion and last year&#8217;s Olympic winner, and the United States&#8217;\u00a0<strong>Rex Maurer<\/strong>. Winnington clocked 3:46.37 for 10th place while Maurer, whose time of 3:43.33 from last month&#8217;s U.S. Nationals, ended up 11th in 3:46.38. The other American,\u00a0<strong>Luka Mijatovic<\/strong>, struggled mightily in his first World Championships swim, ending up 16th and almost 14 seconds off his runnerup effort from Nationals in 3:59.68.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"618066\" data-permalink=\"https:\/\/www.swimmingworldmagazine.com\/news\/world-championships-day-1-mens-prelims-sam-short-lukas-martens-set-up-400-free-title-clash\/screenshot-2025-07-26-234401\/\" data-orig-file=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401.png\" data-orig-size=\"1110,504\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Screenshot 2025-07-26 234401\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-700x500.png\" data-large-file=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-1024x465.png\" class=\"aligncenter size-full wp-image-618066\" src=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401.png\" alt=\"\" width=\"1110\" height=\"504\" srcset=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401.png 1110w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-1024x465.png 1024w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-280x127.png 280w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-300x136.png 300w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-450x204.png 450w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2025\/07\/Screenshot-2025-07-26-234401-533x242.png 533w\" sizes=\"auto, (max-width: 1110px) 100vw, 1110px\" \/><\/p>\n<h2>Men&#8217;s 50 Butterfly<\/h2>\n<p>The first big swim of the prelims came from France&#8217;s\u00a0<strong>Maxime Grousset<\/strong>, who blasted a time of 22.74 in the first seeded heat. He was just four hundredths off his season-best mark of 22.70 that ranks second in the world this year. Grousset previously won bronze in the event at the 2023 Worlds in Fukuoka. Two heats later, Switzerland&#8217;s\u00a0<strong>No\u00e8 Ponti\u00a0<\/strong>equaled that time. Ponti won gold in the 50 and 100 fly at the Short Course World Championships in December after lowering the world record on multiple occasions in the fall.<\/p>\n<p>In between those two performances, <strong>Ilya Kharun<\/strong> put forth a mark of 22.85.

Like nearly all Russian swimmers, Prigoda was absent from international competition for several years, but he made a strong return with six medals at the Short Course World Championships in December, including three relay golds.<\/p>\n<p>Now, Prigoda is in position for another medal performance after he blasted the top time in the world in the 100 breast prelims. Prigoda put forth a time of 58.53, surpassing the 58.61 posted by China&#8217;s\u00a0<strong>Qin Haiyang<\/strong> earlier this year. Prigoda was one of three swimmers to crack 59 in the first of three circle-seeded heats, with Germany&#8217;s\u00a0<strong>Lucas Matzerath<\/strong> (58.75) and Italy&#8217;s\u00a0<strong>Nicolo Martinenghi<\/strong> (58.84) following him to the wall. Martinenghi is the reigning Olympic champion in the event.<\/p>\n<p>Fourth place in that heat was <strong>Caspar Corbeau<\/strong> (59.03), and no one else surpassed that time.

But the Americans remain favorites in the 400 free relay, with a top-seeded performance in prelims cementing that status as high-profile swimmers prepare to join the squad in the evening.<\/p>\n<p>The leadoff swimmer was <strong>Shaine Casas<\/strong>, competing in a freestyle relay for the first time at a long course World Championships. He faded down the stretch on the way to a time of 48.58, but his teammates were dynamite. <strong>Jonny Kulow <\/strong>split 47.51 to put the Americans in the mix before<strong> Destin Lasco<\/strong> moved into the lead with his 47.60.\u00a0<strong>Patrick Sammon<\/strong> finished it off with a 47.48 split that was tied for third-quickest in the entire field.

Alexy clocked a time of 46.99 at last month&#8217;s U.S. Nationals, making him one of only three swimmers at the meet to have ever been so quick.<\/p>\n<p>Australia came in second at 3:11.29, only 0.12 back of the U.S. team, but the Aussies used their top-four finishers from last month&#8217;s selection meet.\u00a0<strong>Flynn Southam<\/strong>,\u00a0<strong>Kai Taylor<\/strong> and\u00a0<strong>Max Giuliani<\/strong> handled the first three legs before\u00a0<strong>Kyle<\/strong> <strong>Chalmers<\/strong>, a three-time Olympic medalist in the 100 free, came home in 47.54.
