With the Indianapolis Pro Series kicking off tomorrow, it’s time to take a look at some of the underlying storylines to keep an eye on as the action unfolds throughout the rest of the week.

Team USA’s Chance to Respond to the Rest of the World

This Indianapolis Pro Series will be an opportunity for a large portion of the US Pan Pacs team to make a statement of their own after recent international meets that saw some very impactful swims, especially in the world rankings. With the US team not having any trials meet heading into the loaded back end of the summer season, this meet could have a trials-meet feel, where several swimmers set to race in Irvine later this summer at Pan Pacs can make their presence felt.

37 of the 52 swimmers on the American Pan Pac roster will compete in Indianapolis, including some of the team’s biggest names, such as Katie Ledecky, Gretchen Walsh, Jack Alexy, and Kate Douglass. In just the last week alone, we saw big-time performances from Egor Kornev and Kliment Kolesnikov in Russia, Sam Short, Lani Pallister, Cam McEvoy, and Kaylee McKeown in Australia. The time to respond could be now, with the intent to show that the US is the team to beat on home soil.

With Pan Pacs being in Irvine, the weight of travel should not sit too heavily on the US team, which also makes every meet and racing opportunity more important as we inch closer to the end of the summer.

Not only is this a response opportunity from swims within the last week, but it also offers a chance to potentially regain the top spot or rise in the world rankings this season. Among those who are in that position is newly minted American Record holder in the 100 freestyle Anna Moesch, whose 51.94 from the AP Race in London only stood as the fastest time in the world for two days before Dutch sensation Marrit Steenbergen halted her parade with a 51.86 at the Mare Nostrum meet in Monaco.

Could Indianapolis Be Home to More Mathias Magic?

The fastest 100 breaststroke in the world this season will be back in action, as former Indiana Hoosier Van Mathias is entered to race in Indianapolis, and with that, could potentially be a new American Record in the 100 breast.

Earlier this season, at the Bergen Swim Festival in Norway, Mathias blasted a 58.19 in the 100 breast, making him the fastest performer in the world this season. Nobody has been able to top that performance, with the next-fastest swimmer this season still sitting nearly half a second off that time, that being Shin Ohashi at 58.67.

His time from the Bergen Swim Festival ranks as the 2nd-fastest American time ever, only behind Michael Andrew‘s 58.14 record. Mathias also leapfrogged up to the #5 performer all time. If he manages to dip under 58 seconds, he would become just the 4th swimmer ever to accomplish that milestone.

That was the same meet that Mathias lowered Nic Fink‘s 50 breast American record in 26.39, a time that still sits atop the world rankings this season.

The last time that Mathias raced was at the Indy Spring Cup in early May, where he clocked a lifetime best in the 50 free in 21.76 and swam a 59.30 in the 100 breast.

No Bowman Swimmers, No Problem

Among the big names missing from this meet in Indianapolis are the names from the all-star assembled training group from Bob Bowman’s training group down in Texas. Some of the biggest absences include Regan Smith, Chris Guiliano, Luke Hobson, Simone Manuel, and Campbell McKean.

Despite all of those major names passing on this meet, the rest of the field makes up for it, especially on the men’s side, where there is a larger number of key American swimmers missing. The meet will still feature Sprint aces Quintin McCarty, Patrick Sammon, and Michael Andrew, while also having solid mid-distance and distance freestylers in Aaron Shackell, Henry McFadden, and Olympic Champion and World Record holder Bobby Finke.

On the women’s side, the only Pan Pac swimmers who will not be in attendance are Jillian Cox, Manuel, McKenzie Siroky, Smith, and Claire Weinstein. But the overall talent and depth on the women’s side pick up any slack left behind.

Some of the other big names in attendance at this meet will be the red-hot backstroker Isabelle Stadden, Claire Curzan, Ryan Murphy, who is making his own comeback after last competing at the Sacramento Pro Series, and the likely headliners of Katie Ledecky and Gretchen Walsh.

Are any American Records in Jeopardy?

We already mentioned that one of the swimmers to watch would be Van Mathias in the 100 breast, as he looks to hunt down that 58.14 American Record, which got us thinking: are there any other marks that may be in danger of falling?

An obvious thought would be Gretchen Walsh in the 100 fly, as she has already broken the World Record in the event this season at the Ft Lauderdale Open in 54.33, that meet was not a championship, though it has been a hot spot for her and world records. Another spot where she has seen some World Record-level success is Indianapolis. In this city, she clocked the fastest-ever 100 fly in 2024 at the US Olympic Swim Trials inside Lucas Oil Stadium. Though this meet will not be held inside a football stadium, Walsh has a knack for the theatrics and for replicating success in places where she has already seen it. It may be a long shot, but if Walsh is on, records could fall.

We already briefly mentioned Isabelle Stadden, who has had a meteoric rise this season. She is entered to race all three backstroke races and is the top seed in both the 100 and 200 back. What could propel her to a potential American Record time could be the competition around her, including Katharine Berkoff, Claire Curzan, Leah Shackley, and Phoebe Bacon, to name a few. But the absence of Regan Smith will be heavily felt here, and if Stadden were to flirt with an American Record, she would also be in the hunt for a potential World Record as well.

Katie Ledecky is back, and in good form. Ledecky’s surprise 800 free World Record last season in Fort Lauderdale was a major sign that she is not yet done dominating. That was also a Pro Series Stop, which this is as well. Ledecky taking down any record here seems to be a bit out there, but the fact of the matter is that she has broken a World Record in Indianapolis before, and broken world records at Pro Series as well. The stage does not need to be the Olympics or World Championships for Ledecky to throw down the fastest-ever time in an event; she needs a lane, and she will have plenty in Indianapolis.
