PHOENIX, Arizona, July 2. WE saw an American record and four US Open records fall at the IU Natatorium, as 50 swimmers were picked to represent the United States at the world championships. Rachel Boostma set the lone American record with a 27.68 in the 50 backstroke to get a place on the world championship team. Bootsma had been chasing that record for more than a year, and with the 50s of butterfly, backstroke and breaststroke contested at nationals for the first time, the opportunity presented itself in a big way for Bootsma.

Missy Franklin broke the US Open record in the 100 back with a 58.67, taking down her own record from the 2012 Olympic Trials in a very fast heat that had four swimmers under 1:00. Three men broke US Open records at the meet, with Kevin Steel's 27.26 in the 50 breast getting the biggest reaction. Steel, a relatively unknown before the meet, beat out Tucson Ford teammate Kevin Cordes for the win and his first senior national international roster spot. David Plummer had a great meet, first breaking the US Open record in the 50 back with a 24.52 then beating a star-studded field in the 100 back to return to worlds in that event. Connor Jaeger wrapped up his stellar meet with a close race in the 800 free, beating Michael McBroom with a 7:46.78, with both of them breaking Chad La Tourett's US Open record.

Across the pond in Great Britain, 27 swimmers were named to that country's world championship team. Jazz Carlin eased Great Britain's worry about who would replace the great Rebecca Adlington with lifetime bests in the 400, 800 and 1500 freestyles. Her time in the mile was a national record.

The biggest surprise in the roster was that Liam Tancock will not get the chance to defend his world title in the 50 backstroke. Since he did not make the team in the 100 backstroke, Tancock was unable to qualify for the 50 back despite beating the qualifying time in the shorter distance.

Michael Jamieson will be the big leader on the men's side after his 2:07.78 in the 200 breast, just ahead of Andrew Willis' 2:08.59. Both were in the Olympic final in the event and could find themselves in the world championship final as well.

Today is the deadline for countries to submit official entries for the swimming events at the world championships, and a few other countries held last-minute trials to try and add more swimmers. The Hungarians held their nationals over the weekend, and Katinka Hosszu was once again the shining star. She won eight events at the meet, though she didn't need to compete there, as she was already qualified for worlds in multiple events. Laszlo Cseh will be one to watch at worlds in the individual medley events, and his 1:58.60 in the 200 IM was a standout for him in Debrecen.

The competition pool at the Palau Sant Jordi is under construction in Barcelona, and these photos provided by the organizing committee show the progress of construction. As you can see, the layout of the pool is very similar to what we saw in Omaha at the Olympic Trials, with some rows of seating removed to make way for the 10-foot deep pool as well as the filtration system underneath it. The skin of the pool, as it is called, is being installed, with the deck around it next on the agenda. The pool will see competition in synchronized swimming in about 19 days, with swimming set to start in 27 days.

Back here in US collegiate news, Indiana University got a big hire to its coaching staff today, as Olympian Jeff Kostoff was hired as assistant coach. Kostoff is most known as the former national high school record holder in the 500-yard freestyle, a record that was broken last February. Kostoff swam for Stanford in the 1980s and at the Olympics in 1984 and 1988. Indiana hired a few others in staff restructuring, and you can read about it on swimmingworld.com.
